Indian Shield: Precambrian Evolution and Phanerozoic Reconstitution highlights unique evolutionary trends covering a period of over 3,500 million years, from the oldest crust to the most recent geological activity of the Indian Subcontinent. The book discusses regional terrain geology in terms of the evolutionary history of the crust, describing how the Precambrian Shield evolved from a stable continental region to a tectonically unstable zone marked by frequent high-intensity earthquakes in a Plate-interior setting. It is a complete and readable account of the history of growth and evolution of the Indian Subcontinent, including Bangladesh, Bhutan, India, Nepal and Pakistan.
The book is intended for graduate students, researchers, and teachers in the geosciences, especially geophysics, geomorphology and geology. The book also serves as an important resource for tectonics and petrology researchers, as well as those involved in exploration of mineral resources.
- Features comprehensive geological information on the evolution of the Indian Subcontinent, from the growth of early crust to the present day in a single volume
- Discusses different processes of post-Precambrian reconstitution of the Indian Shield that ultimately produced the present-day geomorphology as well as the tectonic character of the region
- Assesses the impacts and effects of the ongoing post-Himalayan tectonism on the Indian Subcontinent
