Opis

A sound understanding of the global carbon cycle requires an appreciation of the various physico-chemical and biological processes that determine the production, distribution, deposition and diagenesis of organic matter in the natural environment. This book is a comprehensive interdisciplinary synthesis of this information, coupled with an organic facies approach based on data from both microscopy and bulk organic geochemistry.

Recenzje

...'Encyclopedic'...As the author states in the preface, this work aims to fulfil the need for a synthesis of our current state of knowledge regarding 'the origin, early diagenesis, character, distribution and bulk geochemical composition of sedimentary organic matter' The aim has been acheived admirably...a timely addition for all those involved in the fields of palynological, sedimentological and environmental analyses and hydrocarbon exploration, and should successfully appeal to a wider audience of geological and environmental scientists, especially incoming research students. Sedimentary Organic Matter is surely destined to become a standard reference text for many years to come - Geoscientistn; ...certainly worth purchasing... - Geological Magazine
