This book was released on 2002 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Goldcorp high grade zone at the Red Lake mine in northern Ontario is currently the best Canadian example of high-grade gold mineralization. It provides an opportunity to define the fundamental geological parameters controlling the formation of high-grade gold ore and to assist in developing exploration guidelines for such mineralization. This report updates an ongoing study of the Red Lake high grade zone, beginning with a review of the local geological setting and a description of the southeast-trending structural lineament known as the Red Lake mine trend, defined by folds, faults, and an associated corridor of alteration & mineralization. The report then describes the structure, veins, ore zones, and alteration assemblages in the high grade zone and discusses the chronology of gold replacement, gold remobilization, and the geological controls on formation of the high grade zone.

This book was released on 2002 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper reports on a part of the study of the Goldcorp high-grade zone at the Red Lake gold mine, northern Ontario that carried out fluid inclusion microthermometric analyses on a few key samples representing different stages of gold mineralization. The purpose of the study is to provide an initial idea regarding the fluid characteristics before, during, & after the gold mineralization in order to better understand how the deposit was formed and to contribute to the ongoing debate on its genesis. Fluid inclusions were studied from three different mineral phases: pre-ore carbonate, syn-ore quartz, and post-ore euhedral quartz & associated carbonate. The paper reviews the regional & local geologic setting, the petrography of the samples studied, and the study methods employed, and interprets the microthermometric data with discussion of fluid immiscibility, temperature-pressure conditions of carbonate vein formation & silicification, temperature-pressure conditions of euhedral quartz formation, and the evolution of fluid composition.

Download or read book Selected Mining Districts of Utah written by Carl L. Ege and published by Utah Geological Survey. This book was released on 2005 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whether you are a geologist, history buff, or rockhound, this booklet will be a helpful guide to Utah?s mining districts. The booklet is divided up into three parts: the first part provides general information on what a mining district is, how many mining districts are in Utah, types of mineral deposits found at these districts, and landownership issues. The second part includes individual mining-district discussions containing information on location, production, history, geology, mineralogy, and current/future operations. The third part includes a glossary of geologic terms and other useful resources in the appendices, such as a descriptive list of minerals found in the districts, geologic time scale, and a list of mineral resources of the mining districts.

Download or read book Cochrane Handbook for Systematic Reviews of Interventions written by Julian P. T. Higgins and published by Wiley. This book was released on 2008-11-24 with total page 672 pages. Available in PDF, EPUB and Kindle. Book excerpt: Healthcare providers, consumers, researchers and policy makers are inundated with unmanageable amounts of information, including evidence from healthcare research. It has become impossible for all to have the time and resources to find, appraise and interpret this evidence and incorporate it into healthcare decisions. Cochrane Reviews respond to this challenge by identifying, appraising and synthesizing research-based evidence and presenting it in a standardized format, published in The Cochrane Library (www.thecochranelibrary.com). The Cochrane Handbook for Systematic Reviews of Interventions contains methodological guidance for the preparation and maintenance of Cochrane intervention reviews. Written in a clear and accessible format, it is the essential manual for all those preparing, maintaining and reading Cochrane reviews. Many of the principles and methods described here are appropriate for systematic reviews applied to other types of research and to systematic reviews of interventions undertaken by others. It is hoped therefore that this book will be invaluable to all those who want to understand the role of systematic reviews, critically appraise published reviews or perform reviews themselves.
