Hydrothermal alteration, ore fluid characteristics, and gold depositional processes along a trondhjemite-komatiite contact at Tarmoola, Western Australia .Textures and crosscutting relationships in gold-bearing veins indicate two stages of hydrothermal fluid infiltration associated with a single gold-related hydrothermal event: a. Mineral alteration refers to the various natural processes that alter a mineral's chemical composition or crystallography.. Mineral alteration is essentially governed by the laws of thermodynamics related to energy conservation, relevant to environmental conditions, often in presence of catalysts, the most common and influential being water (H 2 O).. The degree and scales of time in which.

ISSN: Alteration and Alteration Processes Associated with Ore-Forming Systems is a significant volume providing a comprehensive review of alteration related to ore formation. It includes detailed presentations of the theoretical aspects as well as practical approaches to understanding alteration in various ore-forming environments.

processes or alteration in either of the orogenic systems on this study. Hence, these orogenic gold systems are ideal for taking the first steps at constructing a large-scale hydrothermal alteration model.
Further, one of these orogenic gold systems is currently active, so the tectonic setting for the hydrother-mal alteration processes is well. Hydrothermal alteration, also referred to as wallrock alteration, is a general term that encompasses many processes by which rock-forming minerals are altered due to reactions accompanying the flow of heated aqueous fluids along fractures and grain boundaries (Meyer and Hemley, ; Rose and Burt, ; Lentz, ; Reed, ).Alteration may occur through dissolution, ion exchange.
Hydrothermal alteration is proximal to many base and precious metal deposits, and its products can provide insights into the characteristics of hydrothermal systems. To be useful to exploration geologists and researchers, however, alteration needs to be typified and quantified.
