Download or read book Precambrian Continental Crust and its Economic Resources written by S.M. Naqvi and published by Elsevier. This book was released on 1990-09-06 with total page 687 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since 1964, the time when the Upper Mantle Project was started, the Precambrian continental crust has been studied in considerable detail in many areas. Multidisciplinary studies, using modern tools and techniques have resulted in increasing levels of accuracy. The Precambrian continental crust has been subjected to several thermal events and multiple episodes of deformation. These events have obliterated the scenario produced by early events and present-day efforts are directed towards evaluating the cause-effect processes of each event. How far back the known geological processes of the Phanerozoic can be extended into the Precambrian is one of the main questions. The present volume provides data and interpretations which will help in formulating the answer to some of these questions.The book contains 30 contributions resulting from researches on almost all the important Precambrian terranes.

Download or read book Archean Rare Metal Pegmatites in Zimbabwe and Western Australia written by Thomas Dittrich and published by Springer. This book was released on 2019-02-13 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lithium-cesium-tantalum (LCT) pegmatites are important resources for rare metals. For Cs, only the LCT pegmatites with the zeolite group mineral pollucite at Bikita (Zimbabwe Craton) and Tanco (Superior Province Craton) are of commercial importance. Common characteristics of world-class LCT pegmatite deposits include their Meso- to Neoarchean age and geological setting within greenstone belt lithologies on Archean Cratons. This study presents the first coherent and comparative scientific investigation of five major LCT pegmatite systems from the Yilgarn, Pilbara and Zimbabwe Craton. For the evaluation of their Cs potential and of the genetic concepts of pollucite formation, the pegmatites from Wodgina, Londonderry, Mount Deans and Cattlin Creek were compared to the Bikita pollucite mineralization. The integration of the new data (e.g., geochronological and radiogenic isotope data) into the complex geological framework: 1) enhances our knowledge of the formation of LCT pegmatite systems, and 2) will contribute to the further exploration of additional world-class LCT pegmatite deposits, which 3) may host massive pollucite mineralisations.

Download or read book Landmark Papers written by John D. Clemens and published by Mineralogical Society. This book was released on 2012 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: A compilation of landmark papers on granite petrogenesis is overdue. This volume is organized into a number of sections that represent what the editors regard as the main research fields in which progress has been made in understanding granites and their genesis. The origin of granitic magmas is part of the cycle that unites tectonic processes with the generation of mantle magma, crustal growth, the transfer of mantle heat to the crust, high-grade regional metamorphism, crustal melting and crustal differentiation. The extended subject area is far too wide to deal with in a single volume and therefore the selection has been limited to papers dealing with the formation, physical behaviour and chemical evolution of granitic magmas, and just touching on the matter of associated ore deposits. John (JC) Clemens and Fernando Bea are world experts on the subject of granite petrogenesis. Clemens' most important work has been on the origin and evolution of granites and silicic volcanic magmas, experimental studies and modelling of partial melting and the ascent and chemical evolution of granitic magmas, and these continue to be his main interests. Bea's research interests have been in the petrology and geochemistry of granite rocks and the mechanisms of generation of granite magmas, having studied in detail the role of heat-producing elements.
