Supergene and Surficial Ore Deposits

Supergene and Surficial Ore Deposits PDF Author: Bozzano G Luisa
Publisher: Elsevier
ISBN: 0444598995
Category : Nature
Languages : en
Pages : 366

Book Description
Supergene and Surficial Ore Deposits; Textures and Fabrics is a collection of papers that deals with economic geological deposits, particularly as endogenic type, or as an integral part of their geological environment. One paper explores the possibility that the evolution of ores of sedimentary affiliation or of sedimentary rocks and their chemistry during geologic history can be a product of the evolution of the outer spheres of the earth combined with a cycling phenomena that proceeds in a spiral way. Another paper discusses the role of climate on a large range of depositional environments through mobilization, both by chemical and physical events, of metal-ions. Mobilization can also occur by controlled deposition and enrichment of the "mobilized" ions in a certain sedimentary environment. Various depositions occur in different climates, for example, bauxites, requiring higher precipitation levels, form in humid zones. One paper points that ore-mineral accumulations controlled by descending supergene solutions play a significant role in ore-mineral depositions. The collection is beneficial to geologists, industrial chemists, researchers, technical designers, and engineers whose works are related with ore deposits and mining.
