摘要: 笔者通过对四川锦屏山地区金元素的背景分析,总结了该区金矿的同位素特征,并初步分析了该区金矿的流体包裹体特征,讨论了该金矿矿集区的矿源层,提出了该金矿矿集区受伸展-推覆构造的滑移带———褶叠层控制及从矿源、热源、热液源、成矿通道和成矿场所等方面探讨了其成矿模式,指出了该区金矿的找矿方向及找矿层次。

Abstract: The characteristics of stable isotopes and fluid inclusions from the gold deposits in the Jinpingshan area, Sichuan are outlined in the light-of the background analysis of the element Au. The spatial distribution of the-gold deposits in this area is apparent to be controlled by the ductile shear zones of folded beds, i.e. the slip surfaces of the stretching and nappe structures in the gold mineralization areas. The mineralization model is summarized on the basis of the tectonic settings, ore sources, thermal sources, hydrothermal sources, ore channels and metallogenic sites of the gold deposits. According to the mineralization model, the exploration prospects of the gold deposits are tentatively proposed in this paper.
