Download or read book Large Igneous Provinces and their Plumbing Systems written by R. K. Srivastava and published by Geological Society of London. This book was released on 2022-03-15 with total page 598 pages. Available in PDF, EPUB and Kindle. Book excerpt: Identification of large-volume, short-duration mafic magmatic events of intraplate affinity in both continental and oceanic settings on the Earth and other planets provides invaluable clues for understanding several vital geological issues of current concern. Of particular importance is understanding the assembly and dispersal of supercontinents through Earth’s history, dramatic climate change events including mass extinctions, and processes that have produced a wide range of large igneous province (LIP)-related resources, such as Ni–Cu–PGE, Au, U, base metals and petroleum. This volume comprises 21 contributions on the latest developments and new information on LIPs and their plumbing systems and presents methodical studies on different components of LIP plumbing systems. These articles are especially helpful in understanding continental break-up events, regional domal uplift and a variety of metallogenic systems, as well as the temporal and spatial distribution of LIPs, their origin and their likely links to mantle plumes/superplumes.

Book excerpt: Barbara, Meader, and Pifher townships lie on the eastern side of Lake Nipigon and cover an area of 240 sq km. Field work was carried out during the summer of 1986 and consisted of mapping the Precambrian bedrock and mineral deposits. A large number of rock samples were collected, of which 94 were submitted for assays, principally gold and silver, 95 for thin sectioning and 54 for whole rock analysis. This report describes the geology, mineral deposits and exploration history of the area, as well as specific mines.

Available in PDF, EPUB and Kindle. Book excerpt: This report describes the geology, mineral deposits and exploration history of the northern Long Lake area, which includes Houck, Oakes, Croll and Abrey townships; the northern half of Coltham Township; the McBean Lake area, and Long Lake Indian Reserves No. 58 and Ginoogaming First Nation. The area is situated immediately east of the Geraldton gold camp and hosts several gold occurrences, which are being re-evaluated by various companies. The report describes the general geology of the area, then details regional sedimentology, structural geology, metamorphism, the correlation between geology and aeromagnetic data, geochronology, and economic geology, including descriptions of specific and already established properties.

Book excerpt: The map area is located east of Long Lake and comprises Daley Township and the eastern part of Ginoogaming First Nation Indian Reserve, formerly Long Lake Indian Reserve 77. Field work was carried out in summer 1988 and consisted of mapping the Precambrian bedrock and its mineral deposits. Rock samples were collected in the field, with 50 samples submitted for gold and silver assays, 40 for whole-rock geochemistry, and 88 for thin sectioning. This report describes the general geology, rock geochemistry, structural geology, metamorphism and alteration, geochronology, and economic geology of the area, including descriptions of existing properties, and the possibilities for gold, silver, base metals, iron, corundum, stone, and sand and gravel.

Available in PDF, EPUB and Kindle. Book excerpt: The Eye-Dashwa pluton is among the youngest major intrusions in the Atikokan area and is compositionally zoned from a quartz monzodiorite rim to a granite core. This report provides the regional geological setting of the Eye-Dashwa pluton by defining geological boundaries as well as mineralogical, petrological, and geochemical characteristics of the pluton and neighbouring lithological units. Major structural fractures and metamorphic conditions are discussed, and using isotopic age data, the geological events affecting the Archean crust in the area is examined. Certain unresolved problems in Archean geology of the area are identified.
Download or read book Precambrian Geology Vista Lake Area written by P. Mark Smith and published by . This book was released on 1993 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Vista Lake area is approximately 300 sq km, with its centre about 75 km south-southwest of Dryden and 55 km north-northeast of Fort Frances. Mapping was conducted from May-August 1988. Many of the concepts, faults, and lineaments were interpreted fusing geophysical data in addition to field data. Five-five unaltered samples of major volcanic rock types were selected for whole rock, trace element, and rare earth element geochemical analysis. Eight mineralized and later specimens collected were analyzed for selected trace elements. This report describes the general and economic geology of the area, including a description of gold properties.

Book excerpt: The Melgund Lake area includes all of Avery, MacFie and McAree townships in the District of Kenora. The map area is underlain by a diverse assemblage of Archean supracrustal lithologies intruded by Archean felsic granitoid stocks and batholiths. The area had not previously been subjected to detailed geological mapping and the project was undertaken to identify the economic potential of this portion of the Wabigoon subprovince. The economic geology potential of the area includes descriptions of the various properties by township.
