This book describes the microbiota of the intertrappean beds in the Chhindwara District, Madhya Pradesh, India. In this work, special emphasis is placed on the microbiota from the Late Cretaceous-Early Palaeocene transition of the central Narmada River region. Recently, the intertrappean beds of the Eastern Deccan Volcanic Province (one of the subprovinces of the Deccan Volcanic Province) have received considerable attention, which resulted in the addition of some significant biotic assemblages to the existing record from the Dindori-Chhindwara area of the province. The biotic assemblages include charophytes, ostracods, foraminiferans, fishes, frogs, lizards, turtles, crocodiles, and mammals. In spite of the recent discoveries, the known fossil record of the Late Cretaceous-Early Palaeocene biota of India is not sufficient and thus does not permit us to speculate on the possible impact of environmental changes triggered by the Deccan volcanic lava flows on the contemporary biota and to precisely document their palaeoecologic, palaeoenvironmental and palaeobiogeographic implications. The recent biotic reports from the intertrappean beds exposed in the Chhindwara region of the Eastern Deccan Volcanic Province clearly indicate that these beds have a vast potential in terms of fossil content, which could reveal new and dissimilar biotic remains when compared to the Western Deccan Volcanic Province. The record of diverse accumulations of freshwater charophytes, brackish to freshwater ostracods, and planktic foraminiferal and fish assemblages from the intertrappean beds of Jhilmili and adjacent areas of Early Danian (P1a) age and lying just north of Chhindwara town and in the heart of peninsular India has intriguing implications for defining the age limits of the basaltic flows. The occurrence of non-marine taxa, for example, algae, molluscs, and vertebrates, associated with brackish water ostracods in the nearby Singpur and Mohgaon Kalan localities of the Chhindwara region, has also raised concerns about the sedimentary environments of these intertrappean beds. The new finds (presented in this book) prove useful for the better understanding of the palaeoecology and palaeoenvironment of the biota and also throw light on various paleobiogeographic models proposed for the northward drifting Indian plate. The microbiotic assemblages of the intertrappean beds of the eastern Deccan volcanic province at District Chhindwara, Madhya Pradesh are documented in this book. The microbiota of the central Narmada River region, the charophytes, ostracods, planktic foraminifera, and fishes, receive special attention in this study.

This unique book presents hundreds of spectacular photographs of large-scale to small-scale field geological features of flood basalt volcanism from around the world. Major flood basalt provinces covered in this book include the British Palaeogene, Central Atlantic Magmatic Province, Columbia River, Deccan, East Greenland, Emeishan, Ethiopian, Ferrar-Karoo-Tasmania, Iceland, Indo-Madagascar, Paraná, Siberian, West Greenland, and others. Intermediate- to small-sized flood basalts (such as Saudi Arabia and South Caucasus) are also included. Different chapters of the book illustrate varied features of flood basalts, including landscapes, lava flow morphology and stacking, structures formed during lava flow transport, inflation and degassing, structures produced during lava solidification, subaqueous volcanism and volcanosedimentary associations, explosive volcanism, intrusions, igneous processes and magmatic diversity, tectonic deformation, secondary mineralization, and weathering and erosion. This book will be valuable for a large audience: specialists studying flood basalt volcanology, petrology, geochemistry, geochronology, geophysics, and environmental impact and mass extinction links; nonspecialists who want to know more about flood basalts; field geologists (such as those working in geological surveys); students of volcanology and igneous petrology, and even people employed in the industry, such as those working on flood basalt-hosted groundwater or petroleum reservoirs.
