Earth Sciences PAPER  II

1.  GEOLOGY  :

i. Geomorphology  :  Landforms – their types and development; weathering, transport; landforms in relation to rock type, structure and tecionics.  Soils – their development and types.  Geomorphic processes and their impact on various landforms and associated dynamics – slope, channel, coastline, glacial and aaolian; evolution of major geomorphological features of the Indian sub-continent; geomorphometric analysis and modeling.

ii. Sedimentology  :  Classification of sedimentary rocks; petrography of rocks of clastic, chemical and biochemical origin.  Sedimentary textures and structures.  Diagenesis; marine, non-marine and mixed depositional environments.  Facies basin analysis; Reconstruction of palaoenvironments using readioactive and stable isotopes.

iii. Palaeontology  :  Origin and evolution of life; fossils and their uses; species concept; functional morphology, classification and evolution of important invertebrate, vertebrate and piant fossils, biomineralisation and trace fossils; types of microfossils and their applications, palaeobiogeography and palaeoecology; evolution of man.  Oxygen and carbon isotopic studias on fossils; analysis of palaeontological record for tracing plate tectonics processes.

iv. Stratigraphy  :  Recent developments in stratigraphic classification;  Litho bio- and chrono stratigraphic units and their interrelationships; modern methods of stratigraphic correlationl setps in stratigraphic studies; approaches to palaeogeography; Earth’s climatic history.  Rocks of Phanerozoic Eon in India – their intercontinental correlations with special refernce to type localities; boundary problems in stratigraphy; geodynamic evolution of the Indian subcontinent through the Phanerozoic

v. Structural Geology and Geotectonics  :  Concepts of stress and strain; strain analysis using deformed objects; geometric classification of folds; mechanics of folding; folding in shear zones; geometry of superposed folding; structural analysis in terrains with multiple deformation; foliation and lineation; geometry and mechanics of shear zones; brittle-ductile and ductile structures in shear zones; geometry of thrust sheets.  Classification of unfonformities; map patterns and their uses in the determination of large-scale structures.  Isostasy; seismicity; sea-floor spreading and plate tectonics; orogenesis; orogenic baits of India; Evolution of the Himalaya and Himalayan tectonics.
