Book excerpt: The Gospel-Hump Wilderness lies in central Idaho. A mineral survey of the 206,500 acre area in Idaho County was conducted by the U.S. Geological Survey and the U.S. Bureau of Mines during 1980 to 1983. The study consisted of new geologic mapping, geochemical sampling of the wilderness and vicinity, geophysical surveying, and investigation of claim blocks in or near the wilderness. Fractures in the roof zone of plutons of the Idaho batholith host gold and silver deposits in mining districts that are contiguous with and included in the Gospel- Hump Wilderness. Subeconomic gold and silver resources are indicated and inferred at the War Eagle and Blue Jay mines (southeastern part of the area). Parts of the eastern half of the wilderness area, which are included in mining districts and which are along the trends of known mineralized fractures, have a high potential for gold and silver resources and moderate potential for copper, lead, zinc, and molybdenum resources in quartz fissure-veins. Other parts of the wilderness that have the same geologic setting have a moderate potential for gold and silver resources in undiscovered quartz veins that lie along the trend of or are parallel to known veins. The western third of the wilderness has a moderate potential for tungsten, silver, lead, copper, nickel, and possibly gold resources in skarn or metasomatic replacement deposits along thrust faults adjacent to carbonate units.

Download or read book The Paxton Group of Southeastern New England written by Patrick James Barosh and published by . This book was released on 1988 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Paxton Schist of Perry and Emerson (1903), referred to as the "Paxton Quartz Schist" by Emerson (1917), consists of medium-gray, thin- to medium-bedded, fine to coarse-grained schistose granulite, which weathers the same color or slightly darker with a brownish cast. It is pre- Ordovician and probably late Proterozoic in age. The Paxton is herein elevated to group status. The Paxton as revised excludes strata now assigned to the overlying Brimfield Group (Peper and others, 1975). The lower, fine-grained part of the Paxton is herein named the Dudley Formation, and the upper, interbedded, fine to coarse-grained part is referred to as the Southbridge Formation (Pease, 1972). An excellent reference section for the Paxton is present along the north- east side of the Quinebaug River southeast of Southbridge, Mass. The approximate thickness of exposed mapped width of the Paxton is 4,700 meters (m), of which the Dudley forms 1 ,000 m and the Southbridge 3,700 m. The Paxton conformably overlies the Oakdale Formation and underlies the Brimfield Group in its type area in central Massachusetts. It forms a northeast-trending belt extending from east-central Connecticut into southern Maine and probably into the central Maine coast. It is correlative with the Hebron Formation in eastern Connecticut, the upper part of the Berwick Formation in southern Maine, and the Rye Formation on the New Hampshire coast. A slight coarsening of the unit toward the northwest suggests a source in that direction.

Download or read book Regional Trends in the Geology of the Appalachian Caledonian Hercynian Mauritanide Orogen written by P.E. Schenk and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: The classical Appalachian, Caledonian, Hercynian, and Mauritanide orogens are now only segments of a once-continuous Paleozoic mountain belt which has been fragmented during Mesozoic-Cenozoic formation of the North Atlantic Ocean. These segments are major parts of the countries surrounding the North Atlantic - most of which are members of NATO. The aim of this NATO conference was to evaluate these fragments in terms of their pre-Mesozoic positions, and to attempt a synthesis of their geologic evolution on an international and orogen-wide scale. Geologists who have studied these scattered remnants have been separated by both geography and discipline. Orogen-wide syntheses have beeen attempted in the past by individuals who are specialists not only in discipline but also in geography; therefore, these attempts have not been satisfactory to everyone. This conference brought together the foremost specialists in different disciplines from each country. They attempted to teach other specialists, not only in their own fields, but in other disciplines, about regional variations and particular problems. The resulting international cross-fertilization, both within and between speciaLties, enriched individual workers and helped to provide a multi-disciplinary overview of the orogen.
