Sedimentary structures and their relation to bedforms and flow conditions / Осадочные структуры и их связь с подстилающими комплексами и условиями потока

Sedimentary structures that show up in outcrops and cores tell us about physical, biological and sometimes also chemical conditions at the time they were formed. Varying hydraulic or aerodynamic conditions result in assemblages of structures that often bear diagnostic features of sedimentary environments. Therefore an understanding of the origin of sedimentary structures and their assemblages is a prerequisite for sedimentologists and petroleum geologists involved in core description and interpretation. The main objective of this book is to bring together the present basic knowledge on the relation between sedimentary structures, bedforms and hydraulic conditions. The book is part of post-graduate Short Courses in Advanced Sedimentology and Stratigraphy for the petroleum industry offered by ENRES International. In these courses much attention is given to the recognition of sedimentary environments from diagnostic features of sedimentary structures and assemblages of structures. For this purpose practicals are given using a selection of lacquer peels and cores representing typical fluvial to estuarine, coastal and eolian environments. This material including its interpretation is published as a regularly updated stand-alone document that can be obtained from ENRES. <...>
