The Influence of Geological Structures on Gold Deposits: Faults, Shear Zones, and Folds
The Influence of Geological Structures on Gold Deposits: Faults, Shear Zones, and Folds 1. Introduction Gold mineralization is a complex process influenced by a multitude of geological factors, among which structural controls play a pivotal role. This article, based on experiences of Dr. Vinay Sahay in gold exploration, presents the various structural settings that influence gold deposit formation, including fault zones, shear zones, and fold systems. By examining these structures, the mechanisms of gold transport and deposition can be better understood, providing valuable insights for exploration and mining. This article highlights key examples from Archean greenstone belts, mesothermal/orogenic gold deposits, and epithermal gold systems, illustrating the diverse structural environments that host significant gold mineralization. 2. Geological Setting Gold deposits occur in various geological settings, each characterized by specific structural features. These include orogenic...
