This document discusses geological ground prospecting methods and indications. It describes prospecting as the search for outcrops or fragments of ore deposits on the ground. Key stages of prospecting include analyzing sediments, examining mechanical aureoles of fragments, and locating deposit outcrops. Indicator minerals and features like gossans directly show the presence of mineralization. Prospecting methods employ studying natural features to search for deposits. The document outlines prospecting criteria to determine where to look and various prospecting techniques like analyzing colluvium and alluvium or tracing erratic boulders to determine how to look for deposits.

CLASSIFICATION OF ORE DEPOSITS
The Mixture of ore minerals are gangue minerals form an Ore deposit. The ore
deposits are generally found enclosed within the country rocks. The ore deposits
are formed in many different ways. Depending upon the process that may
operate to produce them, the ore deposits may be classified as follow:
Magmatic ore deposits.
Sublimation ore deposits.
Pegmatitic ore deposits.
Contact metasomatic ore deposits.
Hydrothermal ore deposits
Cavity filling deposits.
Replacement deposits.
Sedimentation ore deposits.
Evaporation ore deposits.
Residual and mechanical concentration deposits
Metamorphic ore deposits.
MAGMATIC ORE DEPOSITS:
The magmatic ore deposits are the magmatic products which crystallize from
magmas. The magmatic ore deposits are classified as follows:
o Early magmatic deposits
o Late magmatic deposits
Early magmatic deposits:
Early magmatic deposits are formed during the
early stage of the magmatic period. In this case the
ore minerals crystallize earlier than the rock
silicates. The Minerals of Nickel, Chromium, and
Platinum are usually found as early magmatic
deposits. The early magmatic deposits can be sub
divided into two groups:
o Dissemination deposits
o Segregation deposits
Dissemination deposits:
When magma crystallizes
conditions, a granular igneous rock is formed. In
such a rock early formed crystals of
may occur in dissemination.
Segregation deposits:
Magmatic segregation deposits are
formed as a result of gravitative
crystallization differentiation. In
case, the ore mineral which crystallize
early, get ocean-trated on a particular
part of igneous part. The ore deposits
thus formed are known as “Segregation
deposits”.

ore minerals
such
Late Magmatic Deposits:
The ore deposits which are formed to
called late magmatic deposits. The late magmatic deposits contain those ore
minerals which have crystallized at rather low temperature from the residual
magma. The magma which is left after crystallization of early for
is called residual magma. This magma frequently contains many ore minerals. The
late magmatic deposits include most of the magmatic deposits of iron and
titanium ores, these deposits are almost always associated with mafic igneous
rocks.
SUBLIMATION DEPOSITS:
Sublimation is a very minor process of formation of ore deposits. Sublimation
deposits contain only those minerals which have been volatilized by hear and
subsequently redeposit in the same form at low temperature and pressure. The
sublimation deposits are found associated with Volcanoes and Fumaroles. Sulfur
of this origin has been mined in Japan, Italy, and Mexico.

DEFINITION AND CLASSIFICATION
Proper understanding of origin of mineral deposits and their classification requires the knowledge of formation-temperatures of these deposits. Certain minerals, present over there, give information’s with regard to temperatures of their formations and of the enclosing deposits and they are known as geological thermometers. These geological thermometers may be classed chiefly into the following groups based on their preciseness:
1. The thermometers that record fairly accurately the specific temperature condition of formation of deposits.
2. The thermometers that provide an upper or a lower temperature, above or below which the deposits do not form
3. The thermometers that provide a range of temperature within which the deposits form; and
4. The thermometers that serve as rough indications of temperatures of formation of mineral deposits.
The presence of two or more of less precise geological thermometers in a deposit narrows the range of temperature of formation for the deposits

A Petrographical Approach to Study Mineral Phases Paragenesis of Gold Bearing...Premier Publishers
India hosts several world class gold prospects like Kolar Gold Fields (KGF), Hutti Gold Fields (HGF) and Gadag Gold Fields (GGF). Karnataka is the prime state for gold production since all of these gold deposits are located within. Apart from these world class gold deposits, several other gold prospects in India were identified and exploration activities are under progress. The present study aims to characterize the mineral assemblage and paragenetic phases of gold bearing Precambrian rocks around Hosur village in Gadag Schist Belt through detailed examination by Ore Microscopy. Gadag Schist Belt (GSB) is known by its significance of gold deposits for centuries. Gold mineralization in GSB is associated with tholeiitic meta-andesite, quartz porphyries and argillite greywacke assemblage. The Gadag Gold Field (GGF) constitutes one of the most important auriferous zones of the Archaean Greenstone terrains in Southern India. All known mineralization is in the form of structurally controlled vein systems. The occurrence of the gold is intimately associated with arsenopyrite. Representative samples were studied under polarizing reflected-light microscope to identify and to characterize the mineral phases of gold occurrences and its textural relationships. It has been observed that there are five phases of mineralization only in the third phase gold has formed along with arsenopyrite. Surface morphology of gold and sulphide mineralization was examined under SEM; whereas the elemental analysis of selected sample was carried out using EDS.The present work reveals the clear perception of gold occurrence and mineral phases paragenesis using ore microscopic approach.
Plate tectonics, like crustal evolution, provides a basis for understanding the distribution and origin of mineral and energy deposits. Different types of ores are characterized by distinct geological environment and tectonic settings.
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

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.

3. Geological ground prospecting methods and indications
• “Geological ground Prospecting” is defined as the search for
outcrops of ore deposits or ore fragments on the ground. It covers
geological fieldwork plus the laboratory studies directed to the
discovery of workable mineral concentrations.
• Indicator mineral are mineral species that directly show the
presence of a specific type of mineralisation
• Eg: Indicator minerals as guides to base metal sulphide
mineralisation in Betul Belt, central India.
Presence of gahnite (ZnAl2O4) in the sediments is an important
indicator for the proximity to zinc mineralization.
• Geological prospecting methods employ study of natural features in
the search for mineral deposits.
4. • Prospecting criteria determine the location of the prospecting
work, it answers “where to look” for mineral deposits.
• While prospecting method determine how prospecting is to be
carried out, it answers “how to look” for mineral deposits.

analysis stage
5. Stages in ground prospecting:
1.The ore mineral in the alluvium or colluvium is
sought.
2.Mechanical aureole of ore fragment is examined.
3. Finally the outcrop of the ore deposit is located.
6. Prospecting for deposit outcrop:
Resistant veins form long elevated ridges and form a positive
relief.eg:quartz vein which may host sulphide mineralization.
Eg: In Hutti Belt,Karnataka.
In Bundelkhand granitoid , India.
Tabur hill, Kuala Lumpur-world’s longest quartz ridge(16km) also called dragon’s backbone.
7. Low-resistant veins form depressions and
result in a negative relief.eg:graphite
Eg: In Palamu,Jharkhand.
Karst features also exhibit negative
relief.
Eg: Mawsmai cave in Meghalaya.
8. An outcropping ore deposit undergoes certain physical and chemical
changes.
Eg:Coal at surface=high ash,water and low carbon content.
Coal at depth=low ash,water and high carbon content.
Coal at surface
Coal at depth
9. Migration capacity of elements
Enrichment of mineral in gossan:
• Gossan indicates polymetallic deposits underneath.
• In the oxidation zone, some minerals are not altered
while some are significantly leached and still some
others oxidised.
1. Very mobile Eg: K, Ca, Na, Mg
2. Mobile Eg: Cu, Ni, Co, Zn
3. Poorly mobile Eg: Fe, Al, Pt, Au
10. Unaltered
mineral=limonite,corundum
Leached mineral=Zn,Cu
Oxidised mineral=Pb
Eg: St.Anthony deposit of Pb in
U.S.A.
Submicroscopic gold
precipitates in quartz and barite
in concentrations that are 50-
100 times higher than the
primary ore.
eg: gossan in Chitradurga Schist
belt, Karnataka.

12. Prospecting for mechanical aureole of ore fragments.
• Aureole is a zone of altered country rock around an igneous
intrusion or metamorphic body.
• When the resistant vein occur along a slope their fragments
move slowly downward by gravity or solifluction.
Fig: Downward movement of rock under gravity.
13. SOLIFLUCTION
• Solifluction is the flowage of water-saturated soil down a steep slope or slope
permafrost is impermeable to water, Soil
and rock debris gets lubricated by water and flow easily over the underlying
frozen subsoil.
• It is related to freeze-thaw activity. Soil flows occur when the surface layers of
frozen ground thaw in spring.
• Eg: in Jammu and Kashmir.
14. •On finding ore fragments on the surface of a slope prospecting should
proceed upslope and below the surface.
•As deposit outcrop is approached the fragments will occur deeper
below the ground surface and the surface fan will become narrower.
• The form of Aureole depend on the course of the vein and slope
morphology. It may be: 1.areal
2.fan-shaped
Accumulations may be:
• continuous or discontinuous= In gorges. Eg: Palmer gorge.
• Discontinuous= in mountain slopes. Eg:lower parts of the Himalayas.
15. Prospecting based on erratic ore boulders:
Erratic ore boulders are the
fragments of ore minerals
transported by glacier and
deposited in moraine .
Eg: Cu deposit,Finland.
Eg: Erratic granite boulder in
Kangra,India.
• Deposition of erratic boulder is
usuallly in the form of a triangle upto
a distance of 20km and further away
its shape becomes indistinct.
Madison boulder-largest in the U.S.
16. Striations
Primary ore deposit
can be found by tracing
the route of erratic
boulders indicated by
striations on the bed
rock.
During prospecting it
is most promising to
follow the basal moraine.
In scandinavia important
mineral deposit have
been found using this
method.
Eg: Baltoro glacier in
Jammu & Kashmir has
carved striations on the
surrounding country
rock.
17. Prospecting in colluvium
Colluvium is defined as the sediment that has moved downhill under gravity.
Eg: In keralapura, Karnataka.
In Delwara, Rajasthan.
Fig:Unsorted sharp angular
fragments.
18. Prospecting in alluvium
Alluvium is the sediment that has been transported by water.
Useful in prospecting: When Diamond is found in alluvium then
we can trace its source i.e. Kimberlite.
Eg: Platinum mineral in Devangere & Uttar Kannada,Karnataka
Heavy minerals in quartz beach sand,Chennai.
Fig: rounded fragments.
19. Conclusion
Geological ground Prospecting is defined as the
search for outcrops of ore deposits or ore fragments
on the ground.
Indications directly shows of the presence of ore.
Ground prospecting methods employ natural
features in the search for mineral deposits.
There are 3 stages of prospecting i.e. prospecting
for: deposit outcrops ,aureoles and erratic boulders.
