Historical Geology of India


Book Description

‘Historical Geology of India’ is a text book for graduate and post-graduate students of geology, geophysics and other earth sciences for Indian Universities. It also caters to the universities of USA, UK, Australia, New Zealand and Canada as one or two credit courses on regional studies are included in the curriculum. Besides it can be useful to professional geologists and geophysicists working on various projects in India. The book has been specially designed to cover the course content of major Indian Universities and the approved syllabi of the University Grants Commission. This book has not been written in the classical style of what is where and when was it formed; instead there has been an attempt to base the entire history on the time control as available from latest data on high resolution stratigraphy through fossil content, radiometric dating and palaeomagnetic studies. There is a special focus on the tectonic history of the entire subcontinent through time from Precambrian times to present day.







A to Z Geology of India (Stratigraphy and Fossils) (A Bedside Book)


Book Description

The book is in the form of a ready reference. The subject matter of stratigraphy is full of names of formations, groups, etc. At times when we need to know about a certain formation for which we do not know the exact stratigraphic position, then we have to search the entire book, page by page, which becomes quite irritating and time consuming. To overcome this problem, the idea of arranging the different formations in an alphabetic order occurred to the author. During this process it was seen that many small formations, which are otherwise important, do not get their due representation, because they lie in company or association with much larger formations. Otherwise also stratigraphy is nothing but an orderly and chronological arrangement of different formations. In other words, we can say that stratigraphy is a language by itself, where different formations are its words. Same is the case with large number of fossils occurring in different formations. In the usual literature on the subject, it is practically impossible to find in what formation or formations a particular fossil occurs and to which fossil group it belongs. Alphabetical arrangement of fossils as shown in the list of fossils will help students and scholars to persue their task in an easier and quicker way. To arrange such a large number of fossils in an alphabetical order and to find their fossil groups was really a tough job. Still the author does not claim that all the formations and fossils occurring in the Indian stratigraphy are included in this book, and it cannot be the last word on the subject. This is more true in case of fossils, where unlimited literature is available.







Inscriptions of Nature


Book Description

Learn how the deep history of nature became a dominant paradigm of historical thinking, through a study of landscapes of India. Winner of the BSHS Pickstone Prize by the British Society for the History of Science, Shortlisted for the Pfizer Award for an Outstanding Book in the History of Science by the History of Science Society In the nineteenth century, teams of men began digging the earth like never before. Sometimes this digging—often for sewage, transport, or minerals—revealed human remains. Other times, archaeological excavation of ancient cities unearthed prehistoric fossils, while excavations for irrigation canals revealed buried cities. Concurrently, geologists, ethnologists, archaeologists, and missionaries were also digging into ancient texts and genealogies and delving into the lives and bodies of indigenous populations, their myths, legends, and pasts. One pursuit was intertwined with another in this encounter with the earth and its inhabitants—past, present, and future. In Inscriptions of Nature, Pratik Chakrabarti argues that, in both the real and the metaphorical digging of the earth, the deep history of nature, landscape, and people became indelibly inscribed in the study and imagination of antiquity. The first book to situate deep history as an expression of political, economic, and cultural power, this volume shows that it is complicit in the European and colonial appropriation of global nature, commodities, temporalities, and myths. The book also provides a new interpretation of the relationship between nature and history. Arguing that the deep history of the earth became pervasive within historical imaginations of monuments, communities, and territories in the nineteenth century, Chakrabarti studies these processes in the Indian subcontinent, from the banks of the Yamuna and Ganga rivers to the Himalayas to the deep ravines and forests of central India. He also examines associated themes of Hindu antiquarianism, sacred geographies, and tribal aboriginality. Based on extensive archival research, the book provides insights into state formation, mining of natural resources, and the creation of national topographies. Driven by the geological imagination of India as well as its landscape, people, past, and destiny, Inscriptions of Nature reveals how human evolution, myths, aboriginality, and colonial state formation fundamentally defined Indian antiquity.







Mesozoic Stratigraphy of India


Book Description

This book envisages a multi-proxy approach using stable isotopes, geochemical proxies, magnetic susceptibility and associated biotic events for paleoclimatic and paleoenvironmental interpretations of the Mesozoic sedimentary record of India. Mesozoic rocks of India record abnormal sea level rise, greenhouse climate, intensified volcanism, hypoxia in seawater, extensive black shale deposition, and hydrocarbon occurrence. The Mesozoic has also witnessed mass extinction events, evolution of dinosaurs, and breakdown of the supercontinent Pangea and the formation of Gondwana. Although the Mesozoic geology of India has witnessed significant progress in the last century, literature survey reveals a huge gap in knowledge regarding sequence stratigraphy, chemostratigraphy and key geological events. A synthesis of sedimentological, paleontological and chemical data is included to presenting a comprehensive understanding of the Indian Mesozoic record to students, researchers and professionals.




Indian Shield


Book Description

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




Tectonics and Structural Geology: Indian Context


Book Description

This book presents a compilation of findings, review and original works, on the tectonic evolution and structural detail of several terrains in India. It captures the tectonic diversity of the Indian terrain, including tectonics of India's coastal areas, the tectonic evolution of Gondwana and Proterozoic (Purana) basins. It also describes the research results of the Indian craton's geo-history, Tertiary Bengal basin, and also the Himalayan collisional zone. Thus the book covers the deformation history of Indian terrain involving strike slip, compressional and extensional tectonics, and ductile and brittle shear deformations.




Precambrian Basins of India


Book Description

This Memoir provides a comprehensive review of the Precambrian basins of the four Archaean nuclei of India (Dharwar, Bastar, Singhbhum and Aravalli-Bundelkhand), encompassing descriptions of the time-space distribution of sedimentary-volcanic successions, the interrelationship between tectonics and sedimentation, and basin histories. Studies of 22 basins within the framework of an international basin classification scheme deepen an understanding of the basin architecture especially for cratonic basins. Most Indian sedimentary successions formed as cratonic to extensional-margin rift and thermal-sag basins, some reflecting mantle plume movement, subcrustal heating or far-field stress. This Memoir shows that Phanerozoic plate-tectonic and sequence stratigraphic principles can be applied to the Precambrian basins of large Archaean provinces. The differences between the stratigraphic architecture of the Indian Precambrian and examples of Phanerozoic basin-fill successions elsewhere are ascribed to variable rates and intensities of the controls on accommodation and sediment supply, and changes inherent in the evolution of the hydrosphere-atmosphere and biosphere systems.
