新疆那拉提成矿带主要成矿类型及成矿规律探讨

Discussion on the main metallogenic types and metallogenic regularity of Nala metallogenic belt,Xinjiang

本文针对新疆那拉提成矿带主要成矿类型及成矿规律,结合理论实践,在简要阐述控矿地质因素的基础上,分析了那拉提成矿带主要成矿类型,探讨了其成矿规律。分析结果表明,在那拉提成矿带主要成矿类型有铜矿、金矿、钨矿及铁矿。其成矿规律包括:造山带基底形成阶段、元古代南天山洋第一次开合阶段、第二次开合阶段及造山与陆内调整阶段等。希望通过本文的分析对新疆那拉提成矿带的开采和利用有一定帮助。

In this paper,according to the main metallogenic types and metallogenic laws of Nala metallogenic belt in Xinjiang,combined with theoretical practice,on the basis of a brief description of ore controlling geological factors,the main metallogenic types of Nala metallogenic belt are analyzed and their metallogenic laws are discussed.The results show that the main ore-forming types in Nala ore belt are copper,gold,tungsten and iron.The metallogenic regularity includes:the formation stage of orogenic basement,the first opening and closing stage of Proterozoic South Tianshan ocean,the second opening and closing stage and the orogenic and intracontinental adjustment stage.It is hoped that the analysis of this paper will be helpful to the exploitation and utilization of Nala ore belt in Xinjiang.
