| 摘 要： | 错阿金矿床赋存于理塘义敦群上三叠统瓦能组变基性火山岩中，金矿体受次级北北西-近南北向韧性-脆韧性剪切变质带控制，与金矿化有关蚀变主要为黄铁矿化、辉锑矿化和硅化、碳酸盐化、金云母化及石墨化。矿床成因为蚀变构造型。甘孜-理塘断裂带北段嗄拉、错阿、海子口三个矿化集中区内大部份化探异常具有面积大、强度高、梯度变化大、元素组合好等特点，具有很好的找矿前景。

| Abstract: | The Cuo＇a Au deposit is confined to basic meta-volcanic rock of the Upper Triassic Waneng Formation. The orebodies are controlled by NNW-trending and sublongitudinal brittle-ductile shearingmetamorphic zone with the development of wallrock alterations such as pyritization, stibnitization, silicification, carbonatization, phlogopitization and graphitization. The Au deposit is tectonic alteration type one. The Gala, Cuo＇a and Haizikou ore spots in the north Garze-Litang fracture-zone are characterized by strong and widespread geochemical anomalies, showing good prospecting perspective. |
