阿勒泰袄多克金矿床地质特征及成矿远景

Geological Characteristics and Metallogenic Prospect of the Aoduoke Gold Deposit in Aletai Area of Xinjiang Uygur Autonomous Region

摘要:

通过研究新疆阿勒泰地区袄多克金矿床地质特征，结合元素地球化学剖面特征及元素组合特征分析，认为袄多克金矿床金及其他多金属元素主要赋存于中泥盆世托克萨雷组变粉砂岩、千枚岩中及顺层侵入的石英闪长岩脉中；金成矿的主要元素组合为AuWBiAgPbZnAs；金矿属于岩浆热液后期形成的构造蚀变岩型金矿。结合区域地质背景及Au，W，Bi等元素地球化学剖面特征，认为该区具有较好的金矿成矿远景。

Abstract:

Through study on geological characteristics of Aoduoke gold deposit in Aletai area, combining with the analysis on geochemical profile characteristics and elements combination characteristics, it is regarded that gold and other metal elements mainly occur in sandstone and phyllite of the middle Devonian and quartz diorite vein which is concordant intrusion. Main element combinations of gold deposit is AuWBiAgPbZnAs, while gold deposit belongs to structural altered rock type which was formed in late magmatic thermal fluid. Combining with regional geological background and Au, W, Mo, Bi element geochemical profile characteristics, it is regarded that there is a good gold metallogenic prospect in this area.
