Gondwana, comprising more than 64% of the present day continental mass, is home to 33% of large igneous provinces (LIPs) and key to understanding the lithosphere–atmosphere system and related tectonics that influenced global climate and sediment production on Earth. Gondwana has many of the largest LIPs, with areas of 200 000 to 2 000 000 km2. Several Gondwana LIPs erupted near active continental margins as well as within continents. The rifting of continents continued even after LIP emplacement or was aborted by a coeval compression and did not open into an ocean. Important contemporary frontiers include understanding significant amounts of synchronous silicic volcanic rocks in mafic LIPs, bringing better stratigraphic constraints supported by precise age dating and volume estimation of LIPs, the possible link between LIP emplacement and biotic crisis, refinement of the existing petrogenetic models and assessing large eruptions and associated societal risk. This volume covers topics on magma emplacements, petrology and geochemistry, source characteristics, flood basalt–carbonatite linkage, tectonics and geochronology of LIPs distributed in Gondwana continents.

Economic Mineralization - the volume sets out to present various aspects of a very broad details of a narrow field of economic mineralization at a time when the competitively growing global economy and the pressing needs of the society are compelling economic geology to grow and pile of data is accumulating and opinions changing very rapidly. The volume incorporates papers, a resultant of information explosion and electrifying conceptual revolution in economic geology, describing the new and exciting results and timely reviews integrating and immense amount of knowledge in the field of geology, exploration, mining, environment, economics, geophysics and geochemistry that has bearing on economic mineralization. The book imbibes sections on crustal evolution and economic mineralization, economic mineralization of igneous application, economic mineralization of sedimentary affiliation, prospecting and exploration and mining, economics and environments. In all the five sections current concepts, problems and probable trends of future research are highlighted. This book will be an invaluable everlasting reference for both industry and academia specializing in economic mineralization and for those who need updated information and current research in the field. It will be equally useful for advance level geology and mining students and research scholars throughout the world.

The print edition is published as 2 hardback volumes, parts A and B, and sold as a set. The Carboniferous was the time of the assembly of Pangaea by the collision of the Gondwanan and Larussian supercontinents, and the principal interval of the late Paleozoic ice ages. These tectonic and climatic events caused dramatic sea-level fluctuations and climate changes and produced a Carboniferous world that was diverse topographically and climatologically, perhaps only rivalled in that diversity by the late Cenozoic world. Furthermore, the Carboniferous was a time of the accumulation of vast coal deposits of great economic and societal significance. The temporal ordering of geological and biotic events during Carboniferous time thus is critical to the interpretation of some unique and pivotal events in Earth history. This temporal ordering is based on the Carboniferous timescale, which has been developed and refined for nearly two centuries. This book reviews the history of the development of the Carboniferous chronostratigraphic scale and includes comprehensive analyses of Carboniferous radioisotopic ages, magnetostratigraphy, isotope-based correlations, cyclostratigraphy and timescale-relevant marine and non-marine biostratigraphy and biochronology.

Over Australia's 2019-20 Black Summer bushfire season, scientists estimate that more than three billion native animals were killed or displaced. Many species - koalas, the regent honeyeater, glossy black cockatoo, the platypus - are inching towards extinction at the hands of mega-blazes and the changing climate behind them. In Flames of Extinction, award-winning science writer John Pickrell investigates the effects of the 2019-2020 bushfires on Australian wildlife and ecosystems. Journeying across the firegrounds, Pickrell explores the stories of creatures that escaped the flames, the wildlife workers who rescued them, and the conservationists, land managers, Aboriginal rangers, ecologists and firefighters on the front line of the climate catastrophe. He also reveals the radical new conservation methods being trialled to save as many species as possible from the very precipice of extinction.
