| 摘 要： | 西南天山是我国著名的砂砾岩容矿型矿床分布区,近年来,由于相继在乌拉根、萨热克、伽师、滴水矿区取得找矿重大突破而引起世人关注,但对于矿床成因一直存在较大的争论。笔者在详细总结该区矿床地质特征和成矿背景基础上,将西南天山砂砾岩容矿矿床划分为乌拉根式、萨热克式、伽师式3种类型,其成因分别为热卤水溶滤成因、热卤水溶滤-构造叠加成因和同生沉积成因。今后在西南天山找矿的重点应集中于2个方面:一是加强库孜贡苏、托云、托帕、克孜勒陶山间盆地的找矿工作和喀什凹陷、萨热克盆地的边部及深部找矿;二是加强柯坪盆地北翼、库拜盆地西缘的地质找矿与评价。

| Abstract: | The southwestern Tianshan mountains is a famous distribution area of glutenite-hosted ore deposits in China, and has been deeply concerned by geologists because of some prospecting breakthroughs in Wulagen, Sareke, Jiashi and Dishui mineral districts in recent years. As the genesis of these deposits remains as a question, this paper summarized the geological characteristics and the mineralization setting in detail, and divided these ore deposits into three types, i.e. Wulagen-type, Sareke-type and Jiashi-type. Their genesis was respectively hot brine leaching, hot brine leaching-superimposed reformation and syngenetic sedimentation. The prospecting emphasis in southwestern Tianshan Mountains should be put on two aspects. First, some exploration blank area should be given more effort, such as Kuzigongsu, Tuoyun, Tuopa and Keziletao intermountain basins, and the margin and deep of Kashi hollow and Sareke basin. Second, minerals assessment and prospecting should be enhanced in the north of Keping basin and the western margin of Kuche-Baicheng basin. |
