哈密双鱼山-野马泉韧性剪切带型金矿构造控矿解析与成因分析

Analysis of Structural Ore Control and Cause of Ductile Shear Zone Type Gold Deposits in the Shuangyushan-Yemaquan in Hami,Xinjiang

双鱼山-野马泉韧性剪切带是东天山近年来发现的重要金成矿带,为拓展找矿思路,本文从该韧性剪切带的控矿构造方面进行剖析,认为在该韧性剪切带主构造面弧状转弯处、构造叠加区、宽度收窄区为矿化富集有利地段。从形成时代、地球化学、矿物组成、成矿构造等方面进行成因分析,认为该韧性剪切带中金矿为构造期后成矿。

Shuangyushan Yemaquan ductile shear zone is an important gold metallogenic belt discovered in East Tian-shan in recent years,in order to expand the prospecting idea,this paper analyzes the ore controlling structure of the duc-tile shear zone.It is considered that the arc bend of main structural surface、Tectonic superposition region、The width Nar-rows of the main structural surface are favorable area for mineralization enrichment.And the genesis is analyzed from the aspects of formation age、geochemistry、mineral composition and metallogenetic structure,It is considered that the gold deposit is late tectonic mineralization in ductile shear zone.
