DOWNLOAD EBOOK →Whether you are a geologist, history buff, or rockhound, this booklet will be a helpful guide to Utah?s mining districts. The booklet is divided up into three parts: the first part provides general information on what a mining district is, how many mining districts are in Utah, types of mineral deposits found at these districts, and landownership issues. The second part includes individual mining-district discussions containing information on location, production, history, geology, mineralogy, and current/future operations. The third part includes a glossary of geologic terms and other useful resources in the appendices, such as a descriptive list of minerals found in the districts, geologic time scale, and a list of mineral resources of the mining districts.

This publication begins with an introduction on skarn terminology and the problems of skarn identification. It then reviews a genetic model of skarn formation and presents descriptive profiles of eight types of skarn deposits; describes the database of at least 735 skarn occurrences in the province, and the number and distribution of skarns in British Columbia according to their associations, class, age, and distribution; and notes the ages of British Columbia skarns and the total production of various metals extracted from British Columbia skarns. Subsequent sections provide information on assays and metal ratios of mineralized skarns, skarn mineralogy, skarn mineral chemistry, chemistry of skarn-related intrusions, and the mapping and evaluation of skarns. The appendix contains a listing of 735 skarn occurrences in British Columbia, giving deposit name, MINFILE number, latitude/longitude, elements and minerals present, and associated rocks and their ages.

DOWNLOAD EBOOK →Mineral deposits have supplied useful or valuable material for human consumption long before they became objects of scientific curiosity or commercial exploitation. In fact, the earliest human interest in rocks was probably because of the easily accessible, useful (e. g. , red pigment in the form of earthy hematite) or valuable (e. g. , native gold and gemstones) materials they contained at places. In modem times, the study of mineral deposits has evolved into an applied science employing detailed field observations, sophisticated laboratory techniques for additional information, and computer modeling to build complex hypotheses. Understanding concepts that would someday help geologists to find new mineral deposits or exploit the known ones more efficiently have always been, and will continue to be, at the core of any course on mineral deposits, but it is a fascinating subject in its own right, even for students who do not intend to be professional economic geologists. I believe that a course on mineral deposits should be designed as a "capstone course" that illustrates a comprehensive application of concepts from many other disciplines in geology (mineralogy, stratigraphy and sedimentation, structure and tectonics, petrology, geochemistry, paleontology, geomorphology, etc. ). This book is intended as a text for such an introductory course in economic geology, primarily for senior undergraduate and graduate students in colleges and universities. It should also serve as a useful information resource for professional economic geologists.
