赣西小龙金矿热液活动与成矿作用特征
Hydrothermai activity and mineralization of Xiaolong gold deposit, western Jiangxi Province
摘要
Abstract
The Xiaolong gold deposit in western Jiangxi Province is located adjacent to the Zhuting-Jianxi fault belt in Pingle depression, and the gold mineralization is controlled by the west-eastern fault obviously and has a consanguineous connection with the hydrotherrnal fluid penetration.Based on lithology and in site geochemical experiments, the authors hold that the wall rock alteration was dominated by silicification, followed by weak decarbonatization and argillization.According to the theory of mass balance about altered rock and geochemical characteristics of the main elements, the authors obtained enough evidence to afford lithologic conclusions.On such a basis, the authors used the electron microprobe analysis of gold minerals to detect the characteristics of hydrothermal fluid migration.关键词
