Memoir 36 – The Geological Record of Neoproterozoic Glaciations
In recent years, interest in Neoproterozoic glaciations has grown as their pivotal role in Earth system evolution has become increasingly clear. One of the main goals of the IGCP Project number 512 was to produce a synthesis of newly available information on Neoproterozoic successions worldwide similar in format to Hambrey & Harlands (1981) Earths pre Pleistocene Glacial Record. This Memoir therefore consists of a series of overview chapters followed by site-specific chapters. The overview chapters cover key topics including the history of research on Neoproterozoic glaciations, identification of glacial deposits, chemostratigraphic techniques and datasets, palaeomagnetism, biostratigraphy, geochronology and climate modelling. The site specific chapters for 60 successions worldwide include reviews of the history of research on these rocks and up-to-date syntheses of the structural framework, tectonic setting, palaeomagnetic and geochronological constraints, physical, biological, and chemical stratigraphy, and descriptions of the glaciogenic and associated strata, including economic deposits.

Fossil Mammals of Asia: Neogene Biostratigraphy and Chronology

Fossil Mammals of Asia: Neogene Biostratigraphy and Chronology by Xiaoming Wang, Lawrence J. Flynn, Mikael Fortelius
2013 | ISBN: 0231150121 | English | 752 pages | PDF | 20 MB
Fossil Mammals of Asia, edited by and with contributions from world-renowned scholars, is the first major work devoted to the late Cenozoic (Neogene) mammalian biostratigraphy and geochronology of Asia. This volume employs cutting-edge biostratigraphic and geochemical dating methods to map the emergence of mammals across the continent. Written by specialists working in a variety of Asian regions, it uses data from many basins with spectacular fossil records to establish a groundbreaking geochronological framework for the evolution of land mammals.

Asia's violent tectonic history has resulted in some of the world's most varied topography, and its high mountain ranges and intense monsoon climates have spawned widely diverse environments over time. These geologic conditions profoundly influenced the evolution of Asian mammals and their migration into Europe, Africa, and North America. Focusing on amazing new fossil finds that have redefined Asia's role in mammalian evolution, this volume synthesizes information from a range of field studies on Asian mammals and biostratigraphy, helping to trace the histories and movements of extinct and extant mammals from various major groups and all northern continents, and providing geologists with a richer understanding of a variety of Asian terrains.
