    吉尔吉斯马克马尔金矿床地质特征及其意义

    Geological Characteristics and Significance of Makmal Gold Deposit, Kyrgyzstan

    • 摘要: 马克马尔大型金矿床位于吉尔吉斯中天山造山带,属中-酸性侵入体接触交代型金矿床。新疆是中-酸性侵入岩分布广泛地区,目前已发现多处金矿床或矿点分布于中-酸性侵入体内或外接触带。新疆具备这类金矿床的成矿条件和找矿远景,并已找到多纳拉萨依等多个该类型金矿,但目前该类型金矿产地不多,规模不大,笔者通过对马克马尔接触交代型金矿床地质特征的总结,以期对新疆地区该类型金矿床的查找有所帮助。

       

      Abstract: The Makmal large-scale gold deposit, located in Middle Tianshan orogenic belt of Kyrgyzstan, belongs to the contact metasomatic type gold deposit of intermediate-acidic intrusions. The intermediate-acidic intrusive rocks are widely distributed in Xinjiang, where many gold deposits or occurrences are found developed within intermediate-acidic intrusions or their outer contact zone. Thus, the mineralization conditions and prospecting potential of this type of gold deposit are satisfied in Xinjiang, and three middle-scale gold deposits (such as Duonalasayi deposit) have been found there recently. However, this type of gold deposit is less in origin and small in scale. In this paper, the geological characteristics of Makmal large-scale gold deposit have been summarized to provide some help for prospecting this type of gold deposits in Xinjiang.
