This unique book provides a concise account of Indian Paleogene and presents a unified view of the Paleogene sequences of India. The Paleogene, comprising the early part of the Cenozoic Era, was the most dynamic period in the Earth’s history with profound changes in the biosphere and geosphere. The period spans ~42 million years, beginning from post- K/T mass extinction event at ~65 Ma and ending at ~23 Ma, when the first Antarctic ice sheet appeared in the Southern Hemisphere. The early Paleogene (Paleocene–Eocene) has been considered a globally warm period, superimposed on which were several transient hyperthermal events of extreme warmth. Of these, the Palaeocene Eocene Thermal Maxima (PETM) boundary interval is the most prominent extreme warming episode, lasting 200 Ka. PETM is characterized by 2–6‰ global negative carbon isotope excursion. The event coincided with the Benthic Extinction Event (BEE) in deep sea and Larger Foraminifera Turnover (LFT) in shallow seas. Rapid ~60–80 warming of high latitudinal regions led to major faunal and floral turnovers in continental, shallow-marine and deep-marine areas. The emergence and dispersal of mammals with modern characteristics, including Artiodactyls, Perissodactyls and Primates (APP), and the evolution and expansion of tropical vegetation are some of the significant features of the Paleogene warm world. In the Indian subcontinent, the beginning and end of the Paleogene was marked by various events that shaped the various physiographic features of the Indian subcontinent. The subcontinent lay within the equatorial zone during the earliest part of the Paleogene. Carbonaceous shale, coal and lignite deposits of early Eocene age (~55.5–52 Ma) on the western and north-eastern margins of the Indian subcontinent are rich in fossils and provide information on climate as well as the evolution and paleobiogeography of tropical biota. Indian Paleogene deposits in the India–Asia collision zone also provide information pertaining to the paleogeography and timing of collision. Indian Paleogene rocks are exposed in the Himalayan and Arakan mountains; Assam and the shelf basins of Kutch–Saurashtra, Western Rajasthan; Tiruchirappalli–Pondicherry and Andaman and, though aerially limited, these rocks bear geological evidence of immense importance.

Seznam literature o paleogenskih velikih foraminiferah, ki ga je v glavnem sestavil Johannes S. Pignatti, je zelo izčrpen seznam referenc o stratigrafiji, paleoekologiji, morfologiji in taksonomiji paleogenskih velikih foraminifer. Tovrstna literatura seže prav na začetek geološke znanosti in je mnogokrat raztresena v težko dostopnih in manj znanih publikacijah. Sedaj je ta velika količina podatkov, ki bi sicer ostali znani samo redkim specialistom, postala dostopna širši javnosti. Predstavlja nepogrešljivo orodje za vsakogar, ki se ukvarja s katerimkoli področjem geologije in paleontologije paleogena. Kamnine s paleogenskimi velikimi foraminiferami tvorijo marsikje pomembne kolektorje za nafto ali pa so v njih nahajališča drugih gospodarsko pomembnih surovin. Pričujoči seznam bo tako dobrodošel ne le akademskim raziskovalcem, temveč tudi tistim, ki se v praksi ukvarjajo z izkoriščanjem naravnih bogastev.

The book reviews and summarizes the Indian Mesozoic geological evolution in an innovative alternative perspective of sequence stratigraphy. It mainly focuses on the Jurassic interval, but also concisely discusses the preceding Triassic and Cretaceous geological records. The key to the study is primarily held in the recently developed ammonoid based high resolution scales in the Triassic and Jurassic period. The Indian Jurassic record is thus elevated to a high resolution pedestal. The large intra-Jurassic stratigraphic gap in Kachchh, with increase in duration from margin to basin, has been précised in different sections, along with radical revision of its long held interpretation from sub-aerial to sub-marine all over from Arabia to Australia. Other significant gaps are also differentiated into sub-aerial and sub-marine. The Indian Late Precambrian – Neogene record is organized into five mega-sequences. Among these, the fourth – also the most important one – includes the intra-Permian to Early Eocene interval from the origin to the closure of the Neotethys. Based on multidisciplinary integration of the Indian Mesozoic geological record and comparison with hydrocarbon producing basins on east and west of India, a highly positive scenario of the hydrocarbon source/reservoir sediment perspective is outlined in the book in sequence stratigraphic backdrop as an edifice for future elaborate evaluation.

This book addresses time-bound geotectonic evolution of the various geological terrains of the Indian continent, on the basis of integrated geophysical studies, like seismic, seismological, gravity, magnetic, magnetotelluric and heat flow, carried out over the past five decades. Further, it discusses elastic and petrophysical properties of the Earth’s crust relevant to geological investigations. The book also shares latest findings on the geodynamic development of the Indian shield and nearby continental margins, including Arabian Sea.

Obdobje 20 milijonov let, ki je sledilo opustošenju po kredno-terciarni meji in izumrtju dinozavrov, ima posebno mesto v zgodovini Zemlje. V tem času se je postopoma obnavljalo življenje z vso pestrostjo svojih oblik. Podrobno proučevanje tega obnavljanja nam daje ključ za razumevanje vzrokov, zakaj in kako je vzniknila in napredovala raznovrstnost življenja. Pričujoči zvezek je zbir zgodovinskih dokumentov, ki ilustrirajo nekatere od mnogih podob obnove.

"This volume covers new developments and research on mass extinctions, volcanism, and impacts. It addresses the following topics: the Central Iapetus magmatic province; thermogenic degassing in large igneous provinces; global mercury enrichment in Valanginian sediments; Guerrero-Morelos carbonate platform response to the Caribbean-Colombian Cretaceous large igneous province; implications for the Cretaceous-Paleocene boundary event in shallow platform environments and correlation to the deep sea; environmental effects of Deccan volcanism on biotic transformations and attendant Cretaceous/Paleogene boundary mass extinction in the Indian subcontinent; Deccan red boles; and factors leading to the collapse of producers during the Chicxulub impact and Deccan Traps eruptions"--

This book highlights various aspects of geochemical and geological processes. In brief, it facilitates to understand the geochemical behavior of major, trace and rare earth elements in rocks to identify the magmatic processes involved in present-day magma generation and their relation to global tectonic regimes as well as geothermal studies. Therefore, the book provides a comprehensive view of the generation of magma types (mafic to felsic in composition) and their role in the petrogenesis. The book also covers the development of new geosoftware to effectively process the geochemical data before its interpretation.
