通过野外地质、岩相学、拉曼光谱和电子探针分析,对祁雨沟2号和4号含金角砾岩筒中冰长石方解石蚀变矿物组合特征进行了描述。含金角砾岩筒成矿作用分为两期:面状矿化和脉状矿化。面状矿化的蚀变主要有阳起石化、绿色黑云母化、绿泥石化、冰长石化、硅化、绿帘石化、黄铁矿化、碳酸盐化和少量的绢云母化。脉状矿化蚀变为硅化、绢云母化和少量的碳酸盐化。通过对角砾岩筒的蚀变与成矿作用关系研究,认为冰长石方解石蚀变与含金角砾岩金成矿作用是同期,从而确定祁雨沟含金角砾岩筒是一个典型的低硫型浅成低温热液型金矿床。
Through the field geology, petrography, Raman spectroscopy and electron probe analysis, the characteristics of the iced feldspar calcite alteration mineral assemblages in the gold-bearing breccia tubes of Qiyuogou No. 2 and No. 4 were described. The metallogenic breccia tube mineralization is divided into two phases: surface mineralization and vein mineralization. Surface mineralization alteration mainly Yang petrochemical, green biotitization, chloritization, ice feldspar, silicification, epidote, pyrite, carbonate and a small amount of sericitization. Vein mineralization alteration to silicification, sericitization and a small amount of carbonation. Based on the study of the relationship between alteration of diabase conglomerate and mineralization, it is considered that the alteration of iced feldspar calcite is coincidental with the gold mineralization of gold-bearing breccia, so that the Qiyuogou gold-bearing breccia cylinder is a typical Low-sulfur epithermal gold deposits.
