Available in PDF, EPUB and Kindle. Book excerpt: This report describes the geology of tie Contention mine area, a small portion of the Twin Buttes district locatle. in Piria County, 26 miles south-southwest of Tucson, Arizona. The sedimentary rocks exposed in the area are the Bela quartzite and Abrigo limestone of Cambrian age, the Martin limestone of Devonian age, the Escabrosa linestme of Mississippian age, the Naco formation of Pennsylvanian age, and a quartzite of questionable Cretaceous age. The sedimntary rocks are intruded by a biotite granite of probable Tertiary age. Dikes of granite, rhyolite porphyry, and quartz diorite have intruded both the Tertiary granite and the sedimentary rocks. The formations were intensely faulted presumably during the Laramide revolution. Faulting took place in three stages: before the Tertiary intrusion, after the intrusion but before mineralization, and after mineralization. The ore deposits are of the contact metamorphic type with replacement of favorable limestone beds. The mineralizing solutions were apparently derived from the Tertiary magma. Localization of the deposits was mainly influenced by pre-mineral faults. The development of contact silicate minerals has been extensive, and the metamorphism of the sedinentary rocks, intense. Metal production has come from two mines, the Minnie and the Contention. At the Minnie mine the ore mineral was mainly chalcopyrite, whereas at the Contention it was predominantly sphalerite with little chalcopyrite. A search for ore might locate small deposits, especially along the Morgan or Contention faults.

Download or read book Surface Mining Second Edition written by Bruce A. Kennedy and published by SME. This book was released on 1990 with total page 1214 pages. Available in PDF, EPUB and Kindle. Book excerpt: This SME classic is both a reference book for the working engineer and a textbook for the mining student. This hardcover edition gives a brief history of surface mining and a general overview of the state of surface mining today--topics range from production and productivity to technological developments and trends in equipment. This extremely useful text takes the approach that exploration and mining geologists must be expert in a number of fields, including basic finance and economics, logistics, and pragmatic prospecting. Readers will find material on all these topics and more. The book's nine chapters include: Introduction, Exploration and Geology Techniques, Ore Reserve Estimation, Feasibility Studies and Project Financing, Planning and Design of Surface Mines, Mine Operations, Mine Capital and Operating Costs, Management and Organization, and Case Studies. The book is fully indexed.

Available in PDF, EPUB and Kindle. Book excerpt: Long awaited by professional geologists and amateur rockhounds alike, the new Mineralogy of Arizona is a completely revised and greatly expanded edition of a book first published in 1977 and updated in 1982. New material covers 232 minerals discovered in Arizona since the first edition, including 28 first identified in the state. Also new is a section on the history of Arizona mining and mineralogy, which provides context for understanding the significance of mineral discoveries and production since prehistoric times. For nearly 20 years, Mineralogy of Arizona has been respected as the definitive reference on Arizona minerals. Now completely revised and greatly expanded with breathtaking new color photographs, the third edition covers 232 minerals discovered in Arizona since the first edition, including 28 first identified in the state.
