DOWNLOAD EBOOKModern civilizations dependence upon an increasing volume and diversity of minerals makes the search for new ore deposits ever more difficult. Now available from Waveland Press, Guilbert & Parks text presents ideas, principles, and data fundamental for beginning economic geologists to understand the genesis and localization of ore deposits and of the minerals associated with them. The authors comprehensively describe the physical and chemical characteristics of ore deposits and correlate them with environments and conditions of deposition, since ore deposits are best interpreted as extensions of the environments responsible for their enclosing rocks. Examples and illustrations emphasize structural, chemical, and temporal controls and encourage the three-dimensional thinking used by productive explorationists as they face unsolved problems. This upper-level undergraduate text is fully illustrated and meticulously indexed. Its reliable, authoritative coverage assumes an upper-level command of chemistry and physics, as well as mineralogy, petrology, and structural geology. Outstanding features . . . develops and combines the abilities of the explorationist and of the researcher of ore-forming processes structures the geologic descriptions into groupings recognized by researchers and explorers alike builds confidence, revitalizes curiosity, and encourages expanded thinking emphasizes that the days of easy discovery of outcropping ores are not over includes revised, expanded, and updated descriptions of districts

DOWNLOAD EBOOKHandbook of Strata-Bound and Stratiform Ore Deposits, Volume 9: Regional and Specific Deposits focuses on the processes, methodologies, principles, and approaches involved in the identification of regional and specific ore deposits. The selection first elaborates on the timing of mineralization in stratiform copper deposits, oolitic iron formations, and metalliferous deep-sea sediments. Discussions focus on marine distribution and nature of surface and near-surface deposits, structural setting and associated deposits, principal types of deep-sea metal-enriched sediments, chronological development of oolitic-inland-sea iron formation, and complementary sources and transport mechanisms. The text then tackles heavy-metal accumulation in limnic sediments, trace metals in fresh waters, nature and origin of Archaean strata-bound volcanic associated nickel-iron-copper sulphide deposits, and the significance of pyritic black shales in the genesis of Archean nickel sulphide deposits. Topics include lithological associations, oxidation and supergene alteration of ores, temporal and tectonic setting, dissolved metal concentrations in large freshwater systems, and transport phases of heavy metals in river water. The publication examines strata-bound tin deposits, geology of the Pine Point lead-zinc district, and genesis of the Rammelsberg ore deposit near Goslar/Upper Harz in the Federal Republic of Germany. The selection is a valuable reference for researchers wanting to explore ore deposits.

DOWNLOAD EBOOKA model of hte porphyry-metal system characteristic of the consanguineous Cretaceous and Tertiary igneous rocks and associated ores of the southern Rocky Mountains is constructed from the bits and pieces exposed in the Colorado mineral belt and the San Juan volcanic field. Hydrothermally altered rocks in a part of the areas of mineralized rock associated with the Platoro caldera are matched against the model, to locate and to characterize latent mineral deposits for optimal prospecting and exploration. The latent deposits are two stockwork molybdenite deposits (porphyry-molybdenum) and one or two copper-gold-silver chimney deposits.
