Tectonic Processes and Metallogeny along the Tethyan Mountain Ranges of the M...MYO AUNG Myanmar

The genesis of mineral deposits has been widely linked to speci c tectonic settings, but has less frequently been linked to tectonic processes. Understanding processes of oceanic and continental collision tectonics is crucial to understanding key factors leading to the genesis of magmatic-, metamorphic-, hydrothermal-, and sedimentary-related mineral deposits. Geologic studies of most ore deposits typically focus on the nal stages of concentration and emplacement. The ultimate source (mantle, lower crust, upper crust) of mineral deposits in many cases remains more cryptic. Uniquely, along the Tethyan collision zones of Asia, every stage of the conver- gence process can be studied from the initial oceanic settings where ophiolite complexes were formed, through subduction zone and island-arc settings with ultrahigh- to high-pressure metamorphism, to the continental col- lision settings of the Himalaya, and advanced, long-lived collisional settings such as Afghanistan, the Karakoram Ranges, and the Tibetan plateau. The India-Asia collision closed the intervening Neotethys ocean at ~50 Ma and resulted in the formation of the Himalayan mountain ranges, and increased crustal thickening, metamor- phism, deformation, and uplift of the Karakoram-Hindu Kush ranges, Tibetan plateau, and older collision zones across central Asia. Metallogenesis in oceanic crust (hydrothermal Cu-Au; Fe, Mn nodules) and mantle (Cr, Ni, Pt) can be deduced from ophiolite complexes preserved around the Arabia/India-Asia collision (Oman, Ladakh, South Tibet, Myanmar, Andaman Islands). Tectonic-metallogenic processes in island arcs and ancient subduc- tion complexes (VMS Cu-Zn-Pb) can be deduced from studies in the Dras-Kohistan arc (Pakistan) and the various arc complexes along the Myanmar-Andaman segment of the collision zone. Metallogenesis of Andean- type margins (Cu-Au-Mo porphyry; epithermal Au-Ag) can be seen along the Jurassic-Eocene Transhimalayan ranges of Pakistan, Ladakh, South Tibet, and Myanmar. Large porphyry Cu deposits in Tibet are related to both precollisional calc-alkaline granites and postcollisional alkaline adakite-like intrusions. Metallogenesis of continent-continent collision zones is prominent along the Myanmar-Thailand-Malaysia Sn-W granite belts, but less common along the Himalaya. The Mogok metamorphic belt of Myanmar is known for its gemstones associated with regional high-temperature metamorphism (ruby, spinel, sapphire, etc). In Myanmar it is likely that extensive alkaline magmatism has contributed extra heat during the formation of high-temperature meta- morphism. This paper attempts to link metallogeny of the Himalaya-Karakoram-Tibet and Myanmar collision zone to tectonic processes derived from multidisciplinary geologic studies.
This report details the geological observations and interpretations made during a field investigation of the Kaptai Rangamati road-cut section, located in southeastern Bangladesh. The purpose of this report is to document the exposed rock units, their characteristics, and the geological structures present within the road cut.

Geological Field Report On Sitakund Anticline Chittagong, BangladeshShacinChandraSaha
This field report is based on all the scientific facts and data found during the brief field
survey on Sitakund Anticline between Choto Darogar Hat to Barabkund Section. This field
report deals with the physiographic, structural, stratigraphic, sedimentological, and
geomorphic Characteristics of Sitakund Anticline along with their practical and economic
aspects.
The Sitakund Anticline is situated in southern east part of Bangladesh under Chittagong
district. It is about 75 km long and 10 km wide and is one of the westernmost structures of
Chittagong and Chittagong Hill Tracts. The Sitakund range act as water divide between
Halda valley and Swandwip Channel.
Structurally Sitakund Anticline is one of the prominent structures of the eastern folded belt
of Bengal basin. The Sitakund anticline is trending in NNW-SSE direction. It is an
asymmetric fold and the western Flank of the anticline is faulted regionally, the alignment
of which runs parallel to the NNW-SSE trending regional strike.
The Sitakund Anticline is completely composed of sedimentary rock which was deposited
during tertiary age in marginal marine environment. The sedimentary beds are mainly
composed of sandstone and shale but at some places mudstone and siltstone is also found.
So the overall lithology of the area can be described as the alteration of sandstone and shale
with minor presence of mudstone and siltstone at different sites.
In our investigation we got some geomorphic features such as stream, pool, riffle, rapid,
waterfall, slump and pothole etc.
The report gives us the study of rock samples collected from four consecutive sections such
as Sahsradhara Section, Barabkund Section and Chandra Nath Temple Section.5
There are some economical aspects and importance of this area. It is anticipated that there
is reservoir of gas and petroleum in this area. Several gas seepage that we have found in
our investigation are provides a strong evidence of it. Besides many hard rock are supplied
from this area for industrial and construction projects. These areas also have an importance
of religious view.

The research findings showed that coal contains a significant amount of mineral
matter that is mainly composed of clay and quartz, which can be easily seen through
petrographic analysis. The study also identified that the predominant minerals in
Sekoko coal are clay, pyrite, quartz, and carbonate minerals. Organic petrology
revealed that inertinite is the most dominant maceral group, followed by vitrinite and
liptinite. The vitrinite reflectance value ranged from 0.6 to 0.7. Coal from Sekoko coal
mine is enriched in Fe2O3 while host rocks depleted in Fe2O3. X-ray fluorescence
microscopy shows Fe2O3 mean concentration of 1.18 Wt% in coal and Fe2O3 mean
concentration of 0.45 Wt% in host rocks.
In conclusion, coal was of medium rank bituminous C. Significant amounts of pyrite
are present in coal, mostly towards the south of seam 10 as opposed to the west.
The host rocks of the Sekoko coal mine showed no signs of pyrite mineralization.
The study recommended screening and washing of coal prior utilization to help
improve coal quality by reducing the amount of sulfur content in coal.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

ABSTRACT
Department of Earth and Environmental science Bahria university Islamabad had arranged a
four-day field trip to Dir to study its geological and tectonically features. The trip was planed
from 5th to 8th December 2019. The purpose of the field was to let the inexperienced student
to become more comfortable with the diverse geological field strategies and prepare to work
in the field and learn about how it all works. We departed for the field on 5th of December and
10:30 am. During our field we stayed at Shelton hotel Timargara. Our study area was a part of
KIA, that was situated in the northern area of Pakistan. KIA which is sandwiched between
MMT and MKT. The area is highly deformed and showed complex and diverse tectonic feature
along with different minerals and rock unit. The are of KIA was composed of different groups
named as Dir group, Utror volcanic, kamila amphibolite, Yasin group, Gilgit complex and
chilas complex respectively. Diversity of the area is because of thrusting. The area contains
metamorphic and igneous rocks of different origin and types.

CHAPTER # 1
INTRODUCTION
1.1 Location and Accessibility:
Dir which is a small town in District of upper Dir, Khyber-Pakhtunkhwa region, Pakistan
at a rise of 1420 m. It is some of the time known as Dir Khas to recognize it from the area. It
lies at the foot of the Lowarai Pass, the fundamental engine street to Chitral, on the Dir River,
a tributary of the Panjkora River.
Dir was established in the seventeenth century. It was the capital of the previous royal
territory of Dir, until its cancelation in 1969. The previous regal castle is on a slope over the
town. Dir was then the capital of Dir District, however, was supplanted as capital by Timergara,
before the area was partitioned in 1996.
The area of study covers about 900 Sq. Km and is situated between latitude 34° 47 N
to 35° N and longitude 71° 34 E to 71° 55 E in Dir district, northern Pakistan. It covers most
parts of the lower and the upper Dir and Timergara. Timergara is the area and is located about
190 Km north of Peshawar and 85 Km southwest of Dir. The main access to the area is along
Peshawar- Chitral, and Peshawar -Bajaur roads. Several metalled and unmetalled roads connect
various localities of the Timargara area.

CHAPTER # 2
GEOLOGY AND TECTONICS OF DIR
2.1 Geology and Tectonics of Kohistan arc terrane:
The Kohistan arc terrane of northern Pakistan occupies an area of about 36000 Km^2
between the higher Himalayas in the south and Karakoram-Hindukush in the north. It is a part
of the Kohistan-Ladakh island arc, which represents a cross-section through an intra-oceanic
island arc sequence which developed as a part of the northward subduction of Neotethyan
oceanic lithosphere during late Jurassic and Cretaceous times (Honegger et al., 1982;
Tahirkheli and Jan 1979; Searle et al., 1987). This arc mainly comprises a diverse suite of
volcanic, plutonic, and subordinate sedimentary rocks which are variably deformed and
metamorphosed. The Kohistan arc is separated from the Ladakh arc by the N-S trending Nanga
Parbat Haramosh dome (Zeitler, 1985). The Kohistan island arc is bounded by major fault
structures from all sides; it is separated from the Karakoram plate in the north by Northern or
Shyoke suture or Main Karakoram Thrust (MKT), from Indian plate in the south by the Indus
suture or Main Mantle Thrust (MMT) and from the Nanga Parbat- massif in the east by the
Ranikot fault.The Karakoram plate consists of Palaeozoic and subordinate Mesozoic sediments
into which the Khunjarab- Wakhan- Tirichmir granodiorites of the Jurassic to Cretaceous and
the Karakoram batholiths of Cretaceous to Tertiary age are emplaced (Debon et al., 1987). The
Indian plate is made up of Precambrian to Cambrian basement and Palaeozoic to Mesozoic and
Tertiary cover. Several episodes of plutonic activity ranging from Precambrian to Perm-
Triassic and even Himalayan age have been recorded in the Indian plate margin in northern
Pakistan (for detail see Chamberlain et al., 1991; Jan and Karim, 1990; LeFort et al., 1980;
Shams, 1983).
The Kohistan arc contains complete island arc crust including rocks from the top
sedimentary cover to those at the Moho (Tahirkheli et al., 1979; Jan 1980; Bard et al., 1980;
Coward et al., 1985; Miller and Cristenson, 1994). Broad aspects of the tectonic evolution of
the terrane are now reasonably well constrained as a result of reconnaissance mapping,
structural analyses and radiometric dating in the last decade or so. Recent tectonic models for
the development of north-western Himalayas suggest that the initial separation of the Indian
plate from the Gondwanian continent occur at about 120 Ma ago in Early Cretaceous (Powell,
1979). Its rapid movement relative to Australia/Antarctica, with the average rate of 15 cm/year,
took place within 80 Ma to approximately 53 Ma (Powell, 1979) until it collided with Eurasia
11. 4
during the Early Tertiary (LeFort, 1975; Molnar and Tapponnier, 1977; Powell, 1979;
Klootwijk et al., 1992;).
The Indus-Zangpo Suture (ISZ) which represent the collisional boundary in the
southern Tibet, bifurcate further west into MKT (Northern or Shyoke suture) and MMT (Indus
suture) in the Pakistan domain.
These two sutures have been regarded to enclose the Kohistan island arc. This arc
became a continental Andean type margin in front of the Asiatic plate after the closure of a
small back-arc basin along the Northern suture or MKT in the period between 100 and 73 Ma.
Further northward subduction of the Tethyan lithosphere resulted in the final closure of the
Tethys ocean and under thrusting of the Indo-Pakistan plate beneath the Asiatic plate during
50 to 40 Ma along the MMT on the southern side of the Kohistan-Ladakh arc (Powell, 1979;
Searle, 1983; Tahirkheli, 1983; Searle et al., 1987; Petterson and Windley, 1985; Pudsey, 1986;
Pudsey et al., 1985; Coward et al., 1986; Treloar, 1989; Klootwijk et al., 1992). Both the sutures
are characterized by discontinuous outcrops of ophiolites and melanges and in the case of
MMT, blueschist and high-pressure granulite’s (Jan and Howie, 1982; Jan 1991).
In a north-south section, between MKT and MMT, across the Kohistan arc terrane, the
following major lithologies are reported.
2.2 Kohistan-Ladakh granitic belt (Kohistan Batholith):
The presence of Major belt of granitic rocks in the northern part of Kohistan terrane
was identified by Tahirkheli and Jan 1979 and Jan et al. (1981) which was later termed as the
Kohistan batholith by Petterson and Windley (1985) and Coward et al. (1986). This belt
comprises undeformed or mildly deformed intermediate to felsic plutonic rocks.
2.3 Chilas Complex:
Chilas complex is a larger mafic to ultramafic body occupying the middle pail of the
Kohistan terrane for about 300 Km between Dir in the west and Nanga Parbat in the east (Jan
et al., 1984; Khan et al., 1989). The body is internally coherent and attains a maximum width
of about 40 Km in the central parts of the terrane. More than 85% of the Chilas complex is
made up of gabbro-norites, with some hypersthene quartz diorites, gabbro and troctolites (Jan
et al., 1984; Khan et al 1989; 1993)) In the Chilas area the pyroxene quartz-diorite are the
dominant rock types intruding the amphibolites in the north and south of

and quartzite is that phyllite is foliated and non foliated. Rocks of Siluro-Devonian age were
found here.
14. 7
Carbonate Rocks
Carbonate rocks were found of yellowish pink in colour. It shows queering
phenomenon. Fossil record cannot be found due to dolomitization. These were low scattered
hills. Khandarphyllite is of oldest unit, it is pre-Silurian due to its unconformable contact.
Therefore, its age is doubtful.
Economic Importance
It can be used in calcinations process.
Coral Reefs
Its environment of deposition is shallow marine. Reefs were started from bottom. The
reef was a product of organism that precipitates. Bind or retain carbonate and shows upward
growth potential towards the surface of sea.
Economic Importance
Calcium Carbonate can be as cement. Limestone is used for road aggregates. Reef
Breccia was found in angular parts. The term coral means lines in form of colonies.
Fossils
Cephalopods, Brachiopods, Trilobites and Forums were found. All these fossils were
trace fossils means that there remains were not preserved. Its shows butcher chop weathering
in dolomite.
Dip Direction
It is dipping towards north-west direction. It shows the direction of main tectonic force
which is from south to north.

3.3 Jalala Lake Deposits
3.3.1 Latitude: 34°19'53'' N
3.3.2 Longitude: 71°54'30'' E
3.3.3 Observation:
It has horizontal layering. It has very fine-grained silt and clay deposits. Ripple marks
were observed. Graded bedding was found. Sedimentary dikes were following the law of cross
cutting relationship. As we move forward, we see structures showing the difference between
silt and clay. After few steps we saw calcite deposits which were angular, loose and non
cemented, this type of lamination is called varve lamination. Age of the rocks found here was
Siluro-Devonian. Caliche was of due to running water and lake action.

Kamila Amphibolite Unit crops out along the south-eastern periphery of Kohistan
Island arc, bounded between Main Mantle Thrust and Chilas complex, in south and north,
respectively. Kamila Amphibolite unit is further subdivided into four linear belts: Babusar
amphibolites, Niat amphibolites, Jal amphibolites and Sumal amphibolites confined within
Niat and Jal amphibolites. In this sequence of Kamila amphibolites we can also observe weakly
metamorphosed rocks these are non foliated; salt and pepper textures are present. Dark
pyroxene, amphibole and double silicate. Quartz veins are also present, and the shearing
phenomenon is also occurring. Mylonite is also present where shearing is present, abundant
intrusion in the form of dykes related to mafic and ultramafic origin. Granodiorite and granite
are also common.

Baraul Banda in Dir is the type section of the pelitic sequence of Dir Group. Other
accessible sections where Baraul Banda Slates are extensively exposed are north of Kalam on
the western bank of Gabral river in upper Swat and another upstream of Shringal-Panjkora
confluence along Dir road. These two sections run across the strike of slates. Shringal and
Baraul Banda streams running in east-west direction expose the lower contact of the slates with
the Shou Quartzites. Baraul Banda Slates are light grey to greenish grey, thin- bedded, fine
textured and occasionally silty. Light grey, thin- bedded limestone occurs as thin bands in the
24. 17
slates, which are sparingly fossiliferous. The level of metamorphism in the slate’s ranges to
chlorite and sericite grade.

LOWARI ROAD SECTION
DAY 3
5.1 Introduction:
5.1.1 Latitude: 35°04'34''N
5.1.2 Longitude: 71°59'34''E
Epidote has low metamorphic grade and it is often associated with amphiboles,
feldspar. It occurs as a replacement of mineral grains. Weather colour is yellowish green to
green and fresh colour is brownish green to black. We saw perched aquifer in granodiorite
rocks and its recharging phenomenon was controlled by snow. Gabbro and Basalt cannot
transmit and store water. Best igneous reservoir rock is granite due to large size of crystals,
but rock must be in fracture form.

CONCLUSION:
From Nowshera reef complex to Lowari tunnel, we observed different kinds of igneous
and metamorphic structures and rocks. Our knowledge regarding mineralogy was tested
throughout the field because of abundant amount of minerals observed during the field. It really
enables us to easily differentiate between different minerals. Our area of study has shown
complex structures because of the thrusting. It was an outstanding journey of examining and
understanding the geology and tectonic of the area between MMT and MKT mainly Kohistan
island arc.
