湘黔地区金刚石找矿之我见

摘    要:湘黔地区金刚石成矿作用素有"多期"、"多源"之说。"多源"说已为不争事实,系该区开展新一轮金刚石原生矿找矿的依据和前提;笔者质疑"多期"说,并指出加里东期为本区的主要金刚石成矿期,是找矿的主攻方向。在具备成矿条件的前提下,成矿后的剥蚀-保存条件将决定矿床的命运和价值。因金刚石原生矿均系幔源火山作用的产物,由此引申出研究成矿期古剥夷面剥蚀-保存现状的重要性。为提高找矿有效性,在总结以往找矿成功经验和失败教训的基础上,笔者强调找矿工作一定要从我国,尤其是本区的实际出发,运用已被实践证实的成功经验,避免硬套外国模式。

关 键 词:金刚石原生矿  钾镁煌斑岩  加里东期  古剥夷面  指示矿物  重砂法  贵州-湖南

Abstract:Hunan-Guizhou area is one of the diamond metallic deposit area.Multi phase and multi source about the diamond mineralization has been known.Multi source is the accordance and premise for diamond deposit exploration.Multi phase is doubted and Caledonian is the metallogenic period of the diamond deposit in this area,it should be the exploration target.Under the metallogenic condition,the erosion-conservation condition after mineralization decides the density and value of the deposit.Because diamond deposit is the outcome of mantle volcanism,the importance of the condition of erosion-conservation is can be known.In order to increase the efficiency,on the basis of former experiences,everything must be from the actual condition but avoid the foreign model.
Keywords:diamond deposit  lamproite  Caledonian  ancient denudation surface  indicating mineral  heavy mineral method
