摘要: 通过对金矿构造岩、构造矿石的古应力、流体包裹体和物质成分等的研究,探讨了断裂构造从韧性到脆韧性的演化过程中,界面转换成矿的特征,包括动力学特征、流体演化特征、构造对流体的驱动机制等.认为断裂构造从韧性到脆韧性、脆性的演变过程,是成矿物质从分散到局部富集,再到富集成矿的过程,成矿流体的成分也发生相应的变化.

Abstract: By the study on ancient stress, fluid inclusions and composition of tectonites andstructural ores from gold deposits, the ore-forming mechanism of critical transition in ore-bearing ductile-brittle fractures is analyzed, involving the metallogenic dynamics, fluid evolution and the structural mechanism during the evolving process of fractures from ductile to brittle natures. It is concluded that the development of the fractures is also the process of ore-forming matter gathering and enriching, with corresponding change in the composition of ore-forming fluids.
