Sedimentary rock forms through the deposition and lithification of sediment. It is categorized based on its composition and origin into clastic, chemical, and organic types. Clastic sedimentary rock like sandstone and shale form from cemented rock fragments. Chemical sedimentary rock like halite forms from crystallized mineral deposits. Organic sedimentary rock like coal forms from the remains of plants and animals. Sedimentary rock exhibits layers and other structures that indicate its formation history, such as ripple marks, mud cracks, and raindrop impressions preserved in the strata.
Sedimentary texture can be useful in interpreting the mechanisms and environment of deposition. It also has major control over the porosity and permeability of sediment.

Structural and Geological Study of a part of the Chitradurga Schist BeltSai Bhaskar Reddy Nakka
Indian plate consists of several microplates, in the plate tectonic process they merged and disintegrated. The stable part of India i.e., Southern India, consists of several microplates, including the Eastern Dharwad and Western Dharwad in between lies the Chitradurga Schist belt. It has even the primordial rocks and rich in minerals. It was a pleasure to see the oldest rocks and understand all the structural changes happened in the history. This structural and geological study gives a glimpse into one of the oldest parts on earth. I am thankful to Prof. K. V. Subba Rao, a very well known Geologist of India for introducing me to this field area.

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”.

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.
All Igneous rock textures with examples in easy and simple way to understand and increase microscopic studies skills and the way to easily identify igneous rocks under polarized microscope.
ALL ABOUT WEATHERING AND EROSION .. Weathering causes the disintegration of rock near the surface of the earth. Plant and animal life, atmosphere and water are the major causes of weathering. Weathering breaks down and loosens the surface minerals of rock so they can be transported away by agents of erosion such as water, wind and ice. There are two types of weathering: mechanical and chemical.

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.

2. Objectives: Describe the origin of sedimentary rock. Describethe three main categories of sedimentary rock. Describe three types of sedimentary structure.
3. Origins of Sedimentary Rock Wind, water, ice, sunlight, and gravity all cause rock to physically weather into fragments Through erosion, these rock and mineral fragments, called sediment, are moved from one place to another. The sediment is deposited in layers, and eventually newer layers cover the older layers.
4.
5. The most noticeable feature of sedimentary rock is its layers, or strata. A single, horizontal layer of rock is sometimes visible for many miles.
6. Composition of Sedimentary rock Sedimentary rock is classified by the way it forms. Clastic sedimentary rock made of fragments of rocks cemented together by a mineral such as calcite or quartz. can have coarse-grained, medium-grained, or fine-grained textures. Sandstone Siltstone Conglomerate Shale Fine – grained Course – grained
7. Chemical sedimentary rockforms from solutions of dissolved mineral and water. As rainwater slowly makes its way to the ocean, it dissolves some of the rock material it passes through Some of this dissolved material eventually crystallized and forms the mineral that make up chemical sedimentary rock. Halite
8. Organic sedimentary rock made up of the skeletons and shells of sea animals These remains collect on the ocean floor and eventually become cemented together Coal is a type of organic sedimentary rock that is formed when decomposed plant material is buried beneath sediment and is changed by increasing heat and pressure. Chalk Coal
9. Sedimentary Rock Structures Many features indicate the way sedimentary rock is formed Most important feature is stratification the process in which sedimentary rocks are arranged in layers Strata differ from one another depending on Kind Size Color
10.
11. Ripple marks Features in which sedimentary rocks sometimes record the motion of wind and water waves on lakes, oceans, rivers, and sand dunes Mud cracks Structures that form when fine-grained sediments at the bottom of a shallow body of water are exposed to the air and dry out. Even raindrop impressions can be preserved in fine-grained sediments, as small pits with raised rims.
