This book was released on 1996 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dispersion and solubility of Au and other elements in the regolith, and the nature and distribution of regolith materials has been studied at and around the Golden Delicious deposit near Laverton, Western Australia. The deposit has a resource of 6.1 Mt ~ 1.3 g/t Au hosted by a suite of Archaean granitoids that intrude mafic volcanic and volcaniclastic greenschist host rocks in the southern part of the Laverton tectonic zone. The mineralised and country rocks are deeply weathered, and subsequently partly eroded to the clay zone and upper saprolite. They are now covered by up to 20 m of colluvium - alluvium derived from eroding mafic regolith several km to the ESE. Late-stage hematite mega-mottling has overprinted the upper residual horizons. The entire regolith is saturated with saline, weakly alkaline groundwater below approximately 10 m. Much of the regolith, including the transported overburden, has been extensive modified during arid conditions.se across the deposit have been examined in detail to determine element distributions, their relationship to regolith evolution and their significance in exploration. Elements associated with Au mineralisation were W, Sb, K and REE, though none displayed a very direct correlation with Au. Only Au showed evidence of significant remobilization, the other elements approximating their distribution in the Archaean prior to weathering.

This book was released on 2001 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: The distribution and solubility of Au and the distribution of other elements in the upper regolith and the nature and distribution of regolith materials has been studied at and around the Safari deposit, 200 km NE of Kalgoorlie, Western Australia. The deposit has a resource of 1.08 Mt @ 3.3 g/t Au associated with quartz veins within sheared metavolcanic rocks (mainly quartz-chlorite-sericite schists) in the southern extension of the Laverton Tectonic Zone. The mineralised and country rocks are deeply weathered, and subsequently eroded to the lower saprolite and, in places, fresh rock. They are now covered by up to 9 m of colluvium/alluvium derived from eroding greenstone and granite regolith several km to the ENE. Groundwater at the deposit is approximately 40 m below surface. Much of the regolith, and particularly the upper few metres, shows evidence of widespread and intensive modification associated with arid conditions (namely calcification from approximately 0.5-4.0 m below surface).

Download or read book Regolith Science written by Keith Scott and published by CSIRO PUBLISHING. This book was released on 2009-08-18 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive reference on the fundamentals of regolith geoscience describes how regolith is developed from parental rocks and emphasises the importance of chemical, physical, water and biological processes in regolith formation. It provides details for mapping regolith landforms, as well as objective information on applications in mineral exploration and natural resource management. Regolith Science also provides a concise history of weathering through time in Australia. It includes previously unpublished information on elemental abundances in regolith materials along with detailed information on soil degradation processes such as acid sulfate soils. Written by experts in the field, Regolith Science summarises research carried out over a 13-year period within the Cooperative Research Centre for Landscape Environments and Mineral Exploration. This book will be a valuable resource for scientists and graduate/postgraduate students in geology, geography and soil science, professionals in the exploration industry and natural resources management. This paperback edition is a reprint of the original hardback published in October 2008.

This book was released on 1992 with total page 654 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hardbound. The use of exploration geochemistry has increased enormously in the last decade. The present volume specifically addresses those geochemical exploration practices appropriate for tropical, sub-tropical and adjacent areas - in environments ranging from rainforest to desert. Practical recommendations are made for the optimization of sampling, and analytical and interpretational procedures for exploration according to the particular nature of tropically weathered terrains. The underlying theme is the recognition that regions between 35N and 35S in particular have a common history of deep chemical weathering and lateritization during the late Mesozoic and early Tertiary. This has had a profound and lasting effect, so that the surface geochemical expressions of mineralization throughout these regions have many similar features, with local modification due to more recent weathering under changed climates.The volume discusses the da
