Lower Indus Basin and Upper Indus Basin. The Upper Indus
Basin is further divided by Sargodha high way into two parts.
Towards the east of the Sargodha highway in Potwar Plateau
and towards the west is Kohat Plateau. The region of the
North Punjab called as Potwar Plateau is bound in the South
by Salt range and in North by MBT as shown below.
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.

Multi-source connectivity as the driver of solar wind variability in the heli...Sérgio Sacani
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.
Richard's entangled aventures in wonderlandRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.

Introduction:
RNA interference (RNAi) or Post-Transcriptional Gene Silencing (PTGS) is an important biological process for modulating eukaryotic gene expression.
It is highly conserved process of posttranscriptional gene silencing by which double stranded RNA (dsRNA) causes sequence-specific degradation of mRNA sequences.
dsRNA-induced gene silencing (RNAi) is reported in a wide range of eukaryotes ranging from worms, insects, mammals and plants.
This process mediates resistance to both endogenous parasitic and exogenous pathogenic nucleic acids, and regulates the expression of protein-coding genes.
What are small ncRNAs?
micro RNA (miRNA)
short interfering RNA (siRNA)
Properties of small non-coding RNA:
Involved in silencing mRNA transcripts.
Called “small” because they are usually only about 21-24 nucleotides long.
Synthesized by first cutting up longer precursor sequences (like the 61nt one that Lee discovered).
Silence an mRNA by base pairing with some sequence on the mRNA.
Discovery of siRNA?
The first small RNA:
In 1993 Rosalind Lee (Victor Ambros lab) was studying a non- coding gene in C. elegans, lin-4, that was involved in silencing of another gene, lin-14, at the appropriate time in the
development of the worm C. elegans.
Two small transcripts of lin-4 (22nt and 61nt) were found to be complementary to a sequence in the 3' UTR of lin-14.
Because lin-4 encoded no protein, she deduced that it must be these transcripts that are causing the silencing by RNA-RNA interactions.
Types of RNAi ( non coding RNA)
MiRNA
Length (23-25 nt)
Trans acting
Binds with target MRNA in mismatch
Translation inhibition
Si RNA
Length 21 nt.
Cis acting
Bind with target Mrna in perfect complementary sequence
Piwi-RNA
Length ; 25 to 36 nt.
Expressed in Germ Cells
Regulates trnasposomes activity
MECHANISM OF RNAI:
First the double-stranded RNA teams up with a protein complex named Dicer, which cuts the long RNA into short pieces.
Then another protein complex called RISC (RNA-induced silencing complex) discards one of the two RNA strands.
The RISC-docked, single-stranded RNA then pairs with the homologous mRNA and destroys it.
THE RISC COMPLEX:
RISC is large(>500kD) RNA multi- protein Binding complex which triggers MRNA degradation in response to MRNA
Unwinding of double stranded Si RNA by ATP independent Helicase
Active component of RISC is Ago proteins( ENDONUCLEASE) which cleave target MRNA.
DICER: endonuclease (RNase Family III)
Argonaute: Central Component of the RNA-Induced Silencing Complex (RISC)
One strand of the dsRNA produced by Dicer is retained in the RISC complex in association with Argonaute
ARGONAUTE PROTEIN :
1.PAZ(PIWI/Argonaute/ Zwille)- Recognition of target MRNA
2.PIWI (p-element induced wimpy Testis)- breaks Phosphodiester bond of mRNA.)RNAse H activity.
MiRNA:
The Double-stranded RNAs are naturally produced in eukaryotic cells during development, and they have a key role in regulating gene expression .
Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.

1. SOURCE AND RESERVOIR
ROCKS OF PAKISTAN
Muhammad Zahir Kakar EIP-78
Ahtisham Ul Haq EIP-107
Rafiullah Khan EIP-108
2. Introduction Of Source Rock
Source rock refers to rocks from which hydrocarbons have been generated or
capable of being generated.
They are organic-rich sediments that may have been deposited in a variety
of environments including deep water marine, lacustrine and deltaic.
Typical source rocks, usually shales contain about 1% organic matter
Rocks of marine origin tend to be oil-prone, whereas terrestrial source rocks
(such as coal) tend to be gas-prone.
Under the right conditions, source rocks may also be reservoir rocks, as in the
case of shale gas reservoirs.
A source rock is formed by the:
Sedimentation in areas of high organic productivity.
Preservation of organic matter in sediment.
3. Introduction Of Reservoir Rocks
A fundamental property of a reservoir rock is its porosity.
However, for it to be an effective reservoir rock, the fundamental property is
permeability.
Both porosity and permeability are geometric properties of a rock and both
are the result of its lithological (composition) character.
The physical composition of a rock and the textural properties (geometric
properties such as the sizes and shapes of the constituent grains, the manner
of their packing) are what is important when discussing reservoir rocks and
not so much the age of the rock.
4. Sedimentary Basin
Basin is region of the earth of long-term subsidence creating accommodation
space for infilling by sediments.
Pakistan comprises three sedimentary basins.
Indus Basin: (1) Upper Indus Basin (2) Central Indus Basin
(3) Lower Indus Basin
Balochistan Basin
Pishin or kakar khorasan Basin
The Upper Indus Basin (UIB)is the area covering Potwar-Kohat plateau in Punjab
and Khyber-Pathtunkhawa provinces in Northern Pakistan (districts, Jhelum,
Chakwal, Rawalpindi, Islamabad, Attock,Kohat, Karak area).
5. The central indus basin is separated from upper indus basin by the Sargodha
high and pezu uplift in the north.
It is bounded by indian shield in the east, marginal zone of Indian Plate in the
west, and Sukker Riftin the south.
The south indus basin is bounded by the indian shield to the east and the
marginal zone of Inian plate to the west.
Pishin basin is also called kakar khorasan basin.
Kakar khorasan basin is located between Chaman fault in the north and
northwest and obducted ophiolitic margin of Indian Plate in the south.
In the east Balochistan basin is separated from Indus basin by chaman fault,
whereas the western part extend into Iran.
7. Source Rock Of Upper Indus Basin
The Paleocene Patala Formation appears to be the primary source of
hydrocarbons.
There are several potential source rocks in the Kohat-Potwar geologic
province. These include the Late Proterozoic–Lower Cambrian Salt Range;
Permian Wargal, Sardhai, and Chhidru; Paleocene Lockhart; and Eocene
Patala Formations (OGDC, 1996; Quadri and Quadri, 1996).
Chichali and Lumshiwal Formations may be the youngest mature rocks with
source potential throughout most of the Kohat Plateau.
8. Reservoir Rock Of Upper Indus basin
On the Upper Indus basin, oil or gas has been produced
from the following formations:
Cambrian Kherwa, Kussak, and Jutana;
Permian Tobra, Amb, and Wargal;
Jurassic Datta;
Cretaceous Lumshiwal;
Paleocene Khairabad, Lockhart, Patala, and Nammal;
Eocene Bhadrar, Chorgali, and Margala Hill Limestone;
Miocene Murree (Khan and others, 1986; Petroconsultants, 1996).

10. Oil and Gas Field
The Potwar thrust belt has been known for oil production since 1915 when
Khaur field was discovered in district Attock about 100 miles south of
Rawalpindi.
The oldest reservoir for oil, gas and condensate is Khewra formation’s
sandstone of Early Cambrian age in Adhi field near Gujar Khan district
Rawalpindi in Potwar Basin.
The carbonates of Chorgali-Sakesar Formation of Eocene age are the biggest
reservoir in Potwar Basin. The major fields where Eocene fractured
carbonates are reservoirs, Dhulian, Meyal, Pindori, Pariwali, Dhurnal, Dakhni,
Balkassar, Chak naurang, Adhi, Bhangali and Fim Kasser.
Missa Kiswal and Rajian field are also producing oil from Khewra sandstone;
both located not far away from Adhi field.
Late Permain carbonates of Wargal Formation is the reservoir in Dhurnal field.
This reservoir is natural fractured. Dhurnal field is also located in Potwar
Basin near Khaur field.

12.
13. Source Rock Of Lower Indus basin
Total area of lower indus basin is 169,000 ml2.
Sember (Cretaceous) and Ranikot (Paleocene) are main source rock.
Environment of deposition of Sember and ranikot is marine environment.
But there are units with Lower Goru, Ranikot and Ghazij Formation to be
source rock as well.
There are other known and potential source rocks.
Permian Dandot and Tredian Formations,
Triassic Jurassic Datta Formation,
Eocene Ghazij Formation,
lower Miocene shales.
14. Reservoir Rock Of Lower Indus basin
In Kirthar Range mostly Pab sandstone is the reservoir.
Lower Goru Sands (Lower Cretaceous) are the main reservoir for oil and gas.
Habib Rahi limestone (Eocene ) is the gas reservoir in the giant Mari Field.
These fields produce from Sui Main Limestone (SML, Eocene), Ranikot sands,
Dungan limestone (Paleocene) and the Pab sandstone ( Late Cretaceous).
15.
16. Oil and Gas Field
Lower Goru Formation Upper sands and Basal sands are oil bearing in more
than 50 fields in the Badin area in the districts Mirpurkhas, Hyderabad, Badin
and Sanghar in Sindh Province. (Khaskheli, matli, Tando Adam, Turk, Duphri,
Kato, Lashari, Bhatti fields, etc)
Source is Sembar, Reservoir is Sui Main Limestone (Sui, Kandhkot, Loti,
Kandra, Bhadra fields).
Habib Rahi limestone (Mari gas field).
Along Kirthar Range (Mazarani, Mehar, Zamzama, Bhit, Badhra gas fields) Pab
is the reservoir for gas.
