Infos

The earlier editions of this book have been used by successive
generations of students for more than 20 years, and it is the
standard text on the subject in most British universities and many
others throughout the world.



The study of sediments and sedimentary rocks continues to be a
core topic in the Earth Sciences and this book aims to provide a
concise account of their composition, mineralogy, textures,
structures, diagenesis and depositional environments.

This latest edition is noteworthy for the inclusion of 16 plates
with 54 colour photomicrographs of sedimentary rocks in
thin-section. These bring sediments to life and show their beauty
and colorful appearance down the microscope; they will aid the
student enormously in laboratory petrographic work. The text has
been revised where necessary and the reference and further reading
lists brought up-to-date. New tables have been included to help
undergraduates with rock and thin-section description and
interpretation.

* New 16-page colour section will mean students do not need to
buy Longman Atlas

* All illustrations redrawn to higher standard

* Complete revision of text - new material on sedimentary
geochemistry, etc

Autor

Maurice Edwin Tucker is a leading British sedimentologist, specialising in the field of carbonate sedimentology, more commonly known as limestones. From 1993 to 2011 he held the position of Professor of Geological Sciences at the University of Durham, and from 1998 to 2011 was Master of University College, Durham.
