内容説明
This handy pocket-sized guide shows how to achieve successful fieldwork on sedimentary rocks, paying particular detail to the precision and accuracy of recording detail. Various sedimentary rock-types, textures and all the basic field techniques required are clearly described. Thoroughly revised to incorporate up-to-date information, this 3rd edition will be of use to all students and professionals with a geological background. Features include: New sections on safety in the field, the use of GPS in sedimentary studies, core description, fossils as depth indicators and facies models. Improved illustrations and a new updated layout.
