西天山阿吾拉勒成矿带铁矿成矿模式简述

摘要

在二叠纪期间，西天山地区出现了后碰撞伸展环境下的裂谷化过程，区域内构造活动强烈，火山机构十分发育，成矿地质条件有利。区域内矿产资源丰富，分布有查岗诺尔铁矿、智博铁矿、备战铁矿、敦德铁矿等一系列矿产地，矿床多与火山活动成因有密切联系。阿吾拉勒的海相火山岩铁矿成矿模式在新疆是具有代表性的区域，通过对区域主要矿山成矿模式的简述，探讨和思索新的找矿方向。%During the Permian period, western Tianshan mountain was rifted under post-collisional extensional envi-ronment. With strong tectonic activity and well-nurtured volcanic edifice, the metallogenic geological conditions are fa-vorable. At present, it is rich in mineral resources, with Chagangnuoer, Zhibo, Beizhan and Dunde iron ore distributed here whose deposits are closely related to causes of the volcanic action. The iron metallogenic model for marine volcanic of Awuale is typical in Xinjiang. Through introducing the metallogenic models for main mines, this paper discusses new directions for mine exploration.
