Southwest pacific rim gold-copper system: Structure, Alteration, and Mineralization / Типы Au-Cu систем юго-западной части Тихоокеанского кольца

This manual classifies and describes differing styles of southwest Pacific rim gold-copper systems, and analyses hydrothermal ore-forming processes. Investigations of these systems in terms of structure, alteration and styles of mineralization provide information which may help determine the direction of fluid flow within evolving hydrothermal systems. 
Major structures localize magmatic hydrothermal systems in magmatic arc settings and create ore-hosting dilational environments within subsidiary structures, commonly at high angles to the controlling structures. Differing styles of convergence influence the style of major structures and ore-forming environments. Breccias occur in most gold-copper deposits and may be categorised as a guide to understanding the ore-forming environment as broad correlations are apparent between breccia and mineralization styles. Temperature and fluid pH are considered to be the most important of many factors which control the types of hydrothermal alteration. Hydrothermal minerals are classified in terms of these two factors to create a meaningful interpretation of alteration data. Possible mechanisms of metal transport and transport, provide a framework to understand the distribution of metals in intrusion-related systems. <...>
