摘要
云南个旧锡石硫化物矿床是我国著名而又典型的锡多金属矿床,其产出主要受地层岩性、构造和岩浆活动三者的联合控制。从矿床沉积学的角度出发,以矿床(体)产出的地质特征,特别是以矿床(体)宿主岩的宏观、微观含矿性及近矿、远矿围岩的物理机械性质为研究内容,探讨了个旧锡石硫化物矿床产出的岩相古地理条件。作者认为研究此类矿床(体)宿主岩的岩相古地理条件如同研究同生层控矿床的岩相古地理条件一样具有重要意义。
Gejiu Cassiterite-bearing sulfides deposit is a well-known and typical tin polymetallic deposit. The deposit is mainly controlled by the strata, lithology, structure and magmatic rocks. This paper studies lithofacies and paleogeographic conditions for the Gejiu tin deposit from the following aspects : 1 ) geological characteristics of tin orebodies ; 2) macro- and micro-research on host rocks ; 3 ) physical and mechanical properties of the nearby and distal country rocks. It is concluded that lithofacies and paleogeographic conditions for the Gejiu tin deposit has same significance as that for syngenetic stratabound deposits.
