Download or read book Precambrian Geology Slate Islands written by R. P. Sage and published by . This book was released on 1991 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Slate Islands are located in the northeast corner of Lake Superior within the Wawa subprovince of the Superior Province. The islands were field mapped between May 23 and August 15, 1974 and all quartz veins were sampled and checked for their gold content. All sulphide showings were sampled and submitted for emission spectrographic analysis. Sediment samples were obtained from all streams flowing into the lake or encountered on traversing and checked for their heavy metal content. This report describes the general geology, metamorphism and petrochemistry, structural geology, and mineral exploration and deposits of asbestos, copper, iron, sulphides and gold.

Book excerpt: Mednarodna delavnica je obravnavala geološke in biološke posledice katastrofalnih trkov z meteoriti v zgodovini Zemlje od paleozoika do danes. Posebna pozornost je bila posvečena dogodkom na kredno-terciarni meji. Zbornik je razdeljen na tri dele. V prvem delu je 52 povzetkov predavanj in prostorov. Drugi del prinaša pet preglednih člankov o geološki zgradbi zahodne Slovenije in Tržaškega Krasa ter seznam geoloških publikacij in geoloških kart Slovenije, Hrvaške in italijanskega Krasa. Tretji del je vodnik po ekskurzijah. Opisanih je šest profilov, na katerih so odkrite zgornjekredne in najstarejše terciarne plasti.

Download or read book Precambrian Geology written by Alan M. Goodwin and published by Elsevier. This book was released on 2016-02-06 with total page 681 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main goal of this book is to provide a modern comprehensive statement on the Earth's Precambrian crust. It uses geographic and tectonic location, lithostratigraphy, geochronology, and petrogenesis as a basis for considering Precambrian coastal evolution--including the role of plate tectonics. Detailed consideration is given to the endogenic and exogenic processes which formed the continental crust and also to its subsequent secular evolution across Precambrian time**An essential reference volume for every Precambrian geologist.

This book was released on 1984 with total page 622 pages. Available in PDF, EPUB and Kindle. Book excerpt: The lack of a comprehensive treatise on Sudbury geology has beenevident to many geoscientists who have worked or are working inthe Sudbury area. Geoscientists presently working in the Sudburyarea were invited to contribute to a volume on Sudbury geology tocommemorate the bicentenary of Ontario and the centenary ofSudbury. The purpose of this multidisciplinary approach was todocument the geological and geophysical features of the SudburyStructure.

Book excerpt: The conference was held in Snowbird, Utah, October 1988, as a sequel to the Conference on Large Body Impacts held in 1981, also in Snowbird. This volume contains 58 peer-reviewed papers, arranged into sections that cover the major themes of the conference: catastrophic impacts, volcanism, and mass mortality; geological signatures of impacts; environmental effects of impacts; patterns of mass mortality; volcanism and its effects; case histories of mass mortalities; and events and extinctions at the K/T boundary.

Available in PDF, EPUB and Kindle. Book excerpt: The present volume is the result of activities within the scientific programme "Response of the Earth System to Impact Processes" (IMP ACT) of the European Science Foundation (ESF). The ESF is an association of 67 national member organisations devoted to scientific research in 24 European countries. The IMPACT programme is aimed at understanding meteorite impact processes and their effects on the Earth System. Launched in 1998 for a duration of 5 years, the programme is now supported by 15 ESF membership countries. The programme of meteorite impact research and operates through deals with all aspects workshops, exchange programs, and short courses. The 4th IMPACT programme workshop "Meteorite Impacts in Precambrian Shields" took place on May 24-28, 2000, in Lappajarvi, western Finland. A total of 84 scientists from 19 countries from Europe, North America, and Africa participated in the workshop. During the workshop, 43 oral, 31 poster, and several video presentations were made. An exhibition of impactite rocks from Finnish craters and two excursions were organised. The excursion to impact melt rock outcrops of the Lappajarvi structure took place during the workshop. The Karikkoselka and Saaksjarvi impact structures in south-central Finland were visited during the post-meeting excursion.

Download or read book Precambrian Geology of China written by Mingguo Zhai and published by Springer. This book was released on 2015-08-11 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first contribution to the overview of Precambrian geology of China. It covers Precambrian geology of the North China Craton, the South China Craton and the Tarim Craton, as well as other smaller blocks in the Chinese orogenic belts. It provides systematic concepts of the Chinese paleo-continents and incorporates the most up-to-date achievements. Edited by many of the active researchers working at the forefront of the related fields, it contributes greatly to the international Precambrian geology community and would be of interest to geoscientists working in the research field of geology of China and Precambrian geodynamics.
