商品描述

This book provides a comprehensive overview of all major supergene mineral deposits. It discusses both contemporary and classic mineral deposits, drawing on an extensive database that provides the geological, mineralogical, and geochemical characteristics of supergene mineral deposits. Supergene processes or enrichment are those that occur comparatively near to the surface as opposed to deep hypogene processes. Supergene processes include the predominance of meteoric water circulation with concomitant oxidation and chemical weathering. The descending meteoric waters oxidize the primary (hypogene) minerals and redistribute the chemical elements. Supergene enrichment occurs when elements that have been leached from the oxidized rock or ore migrate downward in groundwater and react to changes in the pH, oxidation potential, and chemical composition of water or interact with substrate rock. In these environments, commercially important chemical elements can be enriched to produce an orebody formed entirely by supergene processes. This includes Al (bauxite), Fe (pig iron), Li (brines or evaporites), U (calcretes), REE (clay deposits), base metals (secondary sulfides or gossans), silver, and gold.

商品描述(中文翻譯)

本書提供了所有主要超基因礦床的綜合概述。它討論了當代和經典的礦床,並依據一個廣泛的數據庫,提供超基因礦床的地質、礦物學和地球化學特徵。超基因過程或富集是指那些相對接近地表發生的過程,與深層的隱基因過程相對。超基因過程包括降水循環的主導作用,伴隨著氧化和化學風化。下降的降水會氧化原始(隱基因)礦物並重新分配化學元素。當從氧化岩石或礦石中浸出來的元素在地下水中向下遷移,並對水的pH值、氧化潛力和化學成分的變化作出反應,或與基岩相互作用時,就會發生超基因富集。在這些環境中,商業上重要的化學元素可以被富集,形成完全由超基因過程生成的礦體。這包括鋁(鋁土礦)、鐵(鑄鐵)、鋰(鹽水或蒸發岩)、鈾(石灰岩)、稀土元素(粘土礦床)、基礦(次級硫化物或氧化礦)、銀和金。

He has 35 years of experience in the global mining industry. His background is in exploration and mining in tropical and deeply weathered terrain's including extensive work in Equatorial and Southern Africa, South America and Southeast Asia. He holds degrees in chemistry, geology, chemical engineering and a PhD in geochemistry on the occurrence of oxide gold deposits in Ashanti, Ghana. He has worked for TCL, Ashanti and Minorco prior to joining SRK. For the last 29 years he has worked in mining consulting in the fields of due diligence, financial and technical audits, process chemistry, environmental geochemistry, environmental engineering and mineralogy. Specializes in the application of chemistry and mineralogy to solve engineering problems. Has been involved in the discovery of copper projects that have been developed into mines in DRC, Namibia and Zambia and discovered Gold and Diamond deposits in the Dodoma region of Tanzania and in northern Mozambique. He is currently involved in the development of the Kuene Copper districty in Northern Namibia. He has authored/coauthored over 250 papers, edited monographs and reports including one on Arsenic as Reviews in Mineralogy & Geochemistry, volume 79 and edited as well contributed to volumes on applied chemistry/geochemistry for Nova Publishing series on chemical elements. He is deputy chief editor for Geochemistry, Exploration, Environment and Analysis and past president of the Association of Applied Geochemists.
