This illustrated report is published annually to furnish estimates covering nonfuel mineral industry data. Data sheets contain information on the domestic industry structure, Government programs, tariffs, and 5-year salient statistics for more than 90 individual minerals and materials. Each chapter includes information on events, trends, and issues for each mineral commodity, as well as discussions and tabular presentations on domestic industry structure. Maps, charts, presentations, tables, and graphs are included throughout this text. Geoscientists, petroleum engineers, global community traders, construction industry engineering executives soil scientists, miners, economists, trade brokers specializing in mineral commodities and imports/exports, mineral manufacturers, statistical professionals, and American citizens may be interested in this updated historical reference. Students pursuing coursework for a Bachelor of Science or advanced degree in environmental science, geosciences, or geology may be interested in this volume for research. It is highly recommended that academic libraries with geology and mining engineering programs, special libraries within these fields, and public libraries place an updated annual copy of this primary source work in their business/economic and reference collections.

3C seismic applications provide enhanced rock property characterization of the reservoir that can complement P-wave methods. Continued interest in converted P- to S-waves (PS-waves) and vertical seismic profiles (VSPs) has resulted in the steady development of advanced vector wavefield techniques. PS-wave images along with VSP data can be used to help P-wave interpretation of structure in gas obscured zones, of elastic and fluid properties for lithology discrimination from S-wave impedance and density inversion in unconventional reservoirs, and of fracture characterization and stress monitoring from S-wave birefringence (splitting) analysis. The book, which accompanies the 2016 SEG Distinguished Instructor Short Course, presents an overview of 3C seismic theory and practical application: from fundamentals of PS-waves and VSPs, through to acquisition and processing including interpretation techniques. The emphasis is on unique aspects of vector wavefields, anisotropy, and the important relationships that unify S-waves and P-waves. Various applications and case studies demonstrate image benefits from PS-waves, elastic properties and fluid discrimination from joint inversion of amplitude variations with offset/angle (AVO/A), and VSP methods for anisotropic velocity model building and improved reservoir imaging. The book will be of interest to geophysicists, geologists, and engineers, especially those involved with or considering the use of AVO/A inversion, fracture/stress characterization analyses, or interpretation in gas-obscured reservoirs.
