Hello Swapnajit

Yes you can score good rank in IIT JAM geology by studying in 2 months.

Below is the plan for preparing Topic wise weekly

Week1: The Planet Earth: Origin of the Solar System and the Earth, Geosphere and the Composition of the Earth, Shape and Size of the Earth, Earth-Moon System, Formation of Continents and Oceans, Dating Rocks and Age of the Earth, Volcanism and Volcanic Landforms, Interior of Earth, Earthquakes, Earth’s Magnetism and Gravity, Isostasy, Elements of Plate Tectonics, Orogenic Cycles.

Week2:Geomorphology: Weathering and Erosion, Transportation and Deposition Due to Wind, Ice, River, Sea, and Resulting Landforms, Structurally Controlled Landforms.

Week3:  Structural Geology: Concept of Stratum, Contour, Outcrop Patterns, Maps and Cross Sections, Dip and Strike, Classification and Origin of Folds, Faults, Joints, Unconformities, Foliations and Lineation’s, Shear Zones, Stereographic and Equal Area Projections of Planes and Lines, Computation of True Thickness of Beds from Outcrops and Bore-Holes

Week4:Paleontology: Major Steps in the Evolution of Life Forms, Fossils, Their Mode of Preservation and Utility, Morphological Characters, Major Evolutionary Trends and Ages of Important Groups of Animals – Brachiopod, Mollusca, Trilobite, Graptolitoidea, Anthozoa, Echinodermata, Gondwana Plant Fossils, Elementary Idea of Vertebrate Fossils in India.

Week5:Stratigraphy: Principles of Stratigraphy, Litho-, Chrono- and Biostratigraphy Classification, Distribution and Classification of the Stratigraphic Horizons of India from Archaean to Recent.

Week6:Mineralogy: Symmetry and Forms in Common Crystal Classes, Physical Properties of Minerals, Isomorphism and Polymorphism, Classification of Minerals, Structure of Silicates, Mineralogy of Common Rock-Forming Minerals, Mode of Occurrence of Minerals in Rocks. Transmitted Polarized Light Microscopy and Optical Properties of Uniaxial and Biaxial Minerals.

Week7:Petrology: Definition and Classification of Rocks, Igneous Rocks-Forms of Igneous Bodies, Crystallization from Magma, Classification, Association and Genesis of Igneous Rocks, Sedimentary Rocks – Classification, Texture and Structure, Size and Shape of Sedimentary Bodies. Metamorphic Rocks – Classification, Facies, Zones and Texture. Characteristic Mineral Assemblages of Perlites in the Burrovian Zones and Mafic Rocks in Common Facies.

Week8:Economic Geology: Properties of Common Economic Minerals, General Processes of Formation of Mineral Deposits, Physical Characters, Mode of Occurrence and Distribution in India Both of Metallic and Nonmetallic Mineral Deposits, Coal and Petroleum Occurrences in India.

Make sure that you shoud read atleast 4 to 5 hours daily as you have less time for preparation.

Well I must say you that yes it is possible but not for all possible some for someone but not for all because it depends on your excuses your ability to cross the concept and how fast you can learn the things and how much you can remember so this is skills are different for different people depending upon know you are you may be able to get good score or notyes it is possible but not for all possible sum for someone but not for all because it depends on your skills your ability to cross the concept and how fast you can learn the things and how much you can remember so this is skills are different for different people depending upon know you are you may be able to get good score or not
