新疆天山黑色岩系型矿床的地质特征及找矿方向

    Geological characteristics of black shale-hosted ore deposits and their prospecting in the Tianshan

    • 摘要: 概要介绍了中国天山黑色岩系分布和黑色岩系型矿床的地质特征。中国天山黑色岩系发育,主要集中在古生代,其次为中生代,目前发现与黑色岩系有关的矿种有金、钒、铀、磷、锑。中亚天山黑色岩系中发现了穆龙套和库姆托尔世界级金矿床,中国天山是其东延部分,发现了萨瓦亚尔顿、大山口、萨恨托亥等金矿床,呈现出良好的找矿前景。穆龙套金矿和萨瓦亚尔顿金矿是黑色岩系型金矿的典型代表,中国黑色岩系型金矿与中亚黑色岩系型金矿有许多相似之处。分析认为,吉根—塔尔特库里、乌兰赛尔—大山口、乌什北山、阿克牙孜河等地是最具前景的找金矿靶区,今后应加大萨瓦亚尔顿金矿的勘查和研究力度,同时注意寻找黑色岩系中的铂、钯、铜等矿种。

       

      Abstract: This paper briefly introduces the distribution of black shales and geological characteristics of black shale-hosted mineral deposits in the Chinese Tianshan, Xinjiang. Black shales are well developed in the Chinese Tianshan. They occur mainly in Paleozoic strata and less commonly in Mesozoic strata. Ore minerals associated with black shales found so far are gold, vanadium, uranium, phosphor and antimony minerals. The world-class Muruntau and Kumtor gold deposits in the Central Asian Tianshan occur in black shales, and the Chinese Tianshan is its eastward extension, where the Sawayaerdun, Dashankou and Sahentuohai gold deposits have been discovered in recent years, showing good ore prospects in this region. The Muruntau and Sawayaerdun gold deposits are representatives of black shale-hosted gold deposits. The black shale-hosted gold deposits in the Chinese Tianshan have many similarities to those in the Central Asian Tianshan. Jigen-Taertekuli, Wulansaier-Dashankou, Wushenbeishan and Akeyazihe, Xinjiang, are gold target areas with best gold prospects. In the future, efforts should be intensified to carry out exploration and study of the Sawayaerdun gold deposit and meanwhile attention should be paid to looking for Pt, Pd and Cu deposits in black shales.
