This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract : Hydrothermal native copper deposits are hosted by Mesoproterozoic Midcontinent Rift-filling volcanic and sedimentary rocks in Michigan's Keweenaw Peninsula. The genesis of the native copper deposits has been a point of interest since their discovery. Native copper and associated mineral assemblages vary temporally and spatially. A refined mineral paragenesis is presented and used as the basis to spatially compare mineral assemblages as it is essential that spatial comparison involve only minerals that are temporally/genetically, related to each other. The main-stage minerals associated with precipitation of native copper are spatially zoned. The higher-grade zones correspond to the area of native copper deposits and cross-cut stratigraphy. Late-stage minerals are superimposed on main-stage minerals and are not spatially zoned. The mineral assemblages can be equated to temperature of precipitation through previously published experimental metamorphic petrology, mineral chemistry, and stable isotope pairs. Synthesis of previously published and new light stable isotopic data on hydrothermal minerals are used to draw inferences about the sources of the hydrothermal fluids. The equated temperatures of precipitation with isotopic fractionation equations are used to calculate the isotopic composition of the hydrothermal fluids. The oxygen isotopic composition of main-stage hydrothermal fluids based on isotopic composition of calcite, quartz, and chlorite, when combined with limited hydrogen isotope data for chlorite, epidote, and pumpellyite infer that the fluids were generated by metamorphogenic processes. These copper-bearing hydrothermal/metamorphogenic fluids rose from the deep source zone and mixed with meteoric waters in the zone of precipitation of native copper and associated minerals. Prior to mixing, the relatively shallow meteoric waters may have evolved in the rift-filling clastic sedimentary rocks overlying rift-filling basalts. Main-stage calcite can be distinguished from late-stage calcite by oxygen and carbon isotopes suggesting a different source of the late-stage hydrothermal fluids. The late-stage hydrothermal fluids are primarily meteoric waters although the meteoric waters may also have evolved in the rift-filling sedimentary rocks. Mixing of late-stage fluids with metamorphogenic fluids cannot be precluded. This study confirms the long-held hypothesis that the native copper precipitating hydrothermal fluids were generated by burial metamorphism. The hypothesis that fluid mixing was a mechanism promoting precipitation of native copper is supported by this study. In contrast, post-native copper late-stage fluids are dominantly meteoric water.

Available in PDF, EPUB and Kindle. Book excerpt: As the importance and dependence of specific mineral commodities increase, so does concern about their supply. The United States is currently 100 percent reliant on foreign sources for 20 mineral commodities and imports the majority of its supply of more than 50 mineral commodities. Mineral commodities that have important uses and face potential supply disruption are critical to American economic and national security. However, a mineral commodity's importance and the nature of its supply chain can change with time; a mineral commodity that may not have been considered critical 25 years ago may be critical today, and one considered critical today may not be so in the future. The U.S. Geological Survey has produced this volume to describe a select group of mineral commodities currently critical to our economy and security. For each mineral commodity covered, the authors provide a comprehensive look at (1) the commodity's use; (2) the geology and global distribution of the mineral deposit types that account for the present and possible future supply of the commodity; (3) the current status of production, reserves, and resources in the United States and globally; and (4) environmental considerations related to the commodity's production from different types of mineral deposits. The volume describes U.S. critical mineral resources in a global context, for no country can be self-sufficient for all its mineral commodity needs, and the United States will always rely on global mineral commodity supply chains. This volume provides the scientific understanding of critical mineral resources required for informed decisionmaking by those responsible for ensuring that the United States has a secure and sustainable supply of mineral commodities.

Available in PDF, EPUB and Kindle. Book excerpt: Students of a phenomenon as common but complex as andesite genesis often are overwhelmed by, or overlook, the volume and diversity of relevant information. Thus there is need for periodic overview even in the absence of a dramatic breakthrough which "solves the andesite problem" and even though new ideas and data keep the issues in a state of flux. Thus I have summarized the subject through mid·1980 from my perspective to help clarify the long-standing problem and to identify profitable areas for future research. Overviews are more easily justified than achieved and there are fundamental differences of opinion concerning how to go about them. It is professionally dangerous and therefore uncom mon for single authors, especially those under 35 such as I, to summarize a broad, active field of science in book-length thor oughness. Review articles in journals, multi-authored books, or symposia proceedings appear instead. The single-authored approach is intimidating in scale and can result in loss of thoroughness or authority on individual topics. The alternatives lack scope or integration or both.
