华南3110铀矿床的大地构造成矿特征与成矿模型
TECTONIC CHARACTERS AND METALLOGEN IC MODEL OF THE 3110URANIUM DEPOSIT IN SOUTH CHINA
【摘要】 本文运用“多因复成矿床”的基本理论和方法,对华南3110铀矿床的地质矿化特点及其成矿规律进行了深入的解剖。从区域地质构造的时空演化与成矿作用之间的内在联系,探讨了该矿床的成生与发展过程,以及成矿的物质来源和成矿条件,重新厘定了该矿床的成因,并建立一个具有“层控”、“构控”、“时控”等特点的“多因复成铀矿床”的成矿模式,为进一步找矿勘探提供了新的思路。
【Abstract】 Based on the basic theory and method o f"polygenetic compound deposit",this article analysed geological mineralization characteristics and metallogenic law of the3110uranium deposit.With internal relation between space-time evolve ment and mineralization of regional geologic structures,this article d is-cussed formative and development pr ocess of the deposit,and source and m ineralization condition,accord-ingly confirmed origion of the deposit.Then foundation a model of metall ogmy of"polygenetic compound deposit"which had specialties,such as"strata-bound","rock-bound","time-bound".This provide a new train of thoughts for further prospecting.
【Key words】 Uranium -rich black rock system; metallogenic structure; polygenetic compound deposit; met-allogenic model;
