【摘要】 从成矿构造系统的开放性、成矿构造的有序结构以及成矿构造的功能结构等方面探讨了川西北地区金矿成矿的构造动力学问题。研究表明,该区金矿床成矿构造系统的开放性沟通了不同的圈层和岩石,表现为成矿流体、成矿物质的多源性以及构造矿化的分带性;成矿构造的有序结构表现为剪切变形及热动力变质与构造岩的分带性,以及含金剪切带的热液蚀变分带性;由导矿构造、储矿构造和成矿构造流体等子系统组成了成矿构造的功能结构。更多还原

【Abstract】 Dozens of gold deposits(occurrence) have been found in the Northwest Sichuan Province,a major distribution area of fine disserminated gold deposit,where gold formation is closely related to tectonic evolution.This paper has discussed ore-forming tectonic dynamics. The results show that gold ore-forming structure systems are open systems,which connects different continental layers and rocks,represented by ore-forming fluid,sources of the mineral material and tectonic zoning.The ordered structure of ore-forming tectonite represented by shear deformation, thermodynamic metamorphose, tectonite zoning and hydrothermal alteration of gold-bearing shear belts. The ore-forming function structure is composed of subsystems including mineral transfer,mineral deposition and ore-forming tectonic fluid.更多还原
