The geoscience handbook

"One of the best-kept secrets in geology is this handy compilation of geological information. The essential reference for geoscientists in the field, office, or lab, The Geoscience Handbook provides quick reference for the key metrics and concepts, as well as short tutorials on subjects that may not be familiar to all geoscientists. The Handbook covers diverse subjects, from geophysics to geologic map symbols to GPS usage, and everything in between! The Handbook uses color photos when possible to better illustrate geology in the real world. New to this printing is the revised 2009 Geologic Timescale published by the Geological Society of America. Each book comes with a handy fieldwork ruler and a grain-size scale, both supplied courtesy of the Society for Sedimentary Geology."--Publisher's description
