Reihe: The Geological Field Guide Series

This fourth edition builds on the success of previous editions andfor the first time is produced in full colour throughout withimproved photos and diagrams. It retains its popular pocket sizeand is an essential buy for all students working in the field.
The text shows how sedimentary rocks are tackled in the fieldand has been written for all those with a geological background. Itdescribes how the features of sedimentary rocks can be recorded inthe field particularly through the construction of graphic logs. Insucceeding chapters the various sedimentary rock types, texturesand structures are discussed and shown how they can be describedand measured in the field. There are expanded sections on tracefossils and volcaniclastics along with updated reference list.Finally a concluding section deals briefly with faciesidentification and points the ways towards facies interpretations,and the identification of sequences and cycles.
Key Features:
* Full colour throughout with improved photos, figures anddiagrams in a modern layout.
* Complete revision and update of best selling textbook which ispart of the highly successful Field Guide series.
* Expanded sections on trace fossils and volcaniclastics alongwith updated reference list.
* Handy pocket size with laminated cover.
* Includes supplementary website with downloadable logging sheetsfor fieldwork activities.
