Course Title: Principles of Stratigraphy and Precambrian Stratigraphy of India

(L-P-Tu): 5-0-1

Credit: 6

Practical/Theory: Theory

Course Objective: Principle of Stratigraphy imparts the basic knowledge about the concept of stratigraphy, the basic stratigraphic sub-divisions and geological time scale.

Learning Outcome: students will gather knowledge about regional examples of stratigraphic horizons, as well as earliest timeline of formation of peninsular India in the geological history of earth.

Theory:

Unit I: Principles of stratigraphy

1. Fundamentals of lithostratigraphy, biostratigraphy and chronostratigraphy.

2. Introduction to concepts of dynamic stratigraphy (chemostratigraphy, seismic stratigraphy, Magneto-stratigraphy, sequence stratigraphy).

3. Relevance of Type section. Concepts of Stratotypes. Global Stratotype Section and Point (GSSP)

4. Principles of stratigraphic correlation.

Unit II: Code of stratigraphic nomenclature

1. International Stratigraphic Code – development of a standardized stratigraphic nomenclature with Indian examples

Unit III: Principles of stratigraphic analysis Facies concept in stratigraphy

1. Walther’s Law of Facies.

2. Concept of paleogeographic reconstruction

Unit IV: Stratigraphic boundaries in India

1. Archaean-Proterozoic boundary.

2. Precambrian-Cambrian boundary and their status in global perspective.

Unit V: Physiographic and tectonic subdivisions of India

1. Brief introduction to the physiographic and tectonic subdivisions of India

2. Introduction to Indian Shield, Craton

3. Introduction to Indian Precambrian belts.

4. Introduction to Proterozoic basins of India

Unit VI: Geologic evolution Important Precambrian terrains

1. Geologic evolution with emphasis on sedimetation, lithology, magmatism, structure, metamorphism and geochronology of: Singhbhum, Dharwar, Rajasthan, Central India and Eastern Ghats.

2. Vindhyan and Cudappah basins of India.

3. Peninsula and of Extra-peninsula (Lesser Himalaya)
