摘　　要：简要论述了典型热液裂隙充填钨—铋—钼石英脉矿床地质及其以黑钨矿—辉铋矿—辉钼矿为主的矿物组合纵向逆分带现象。重点测量研究了黑钨矿晶体的宏观形态特征和微形貌,及其成因演化机制。以现代光学微分干涉(DIC)显微镜观察测量了黑钨矿端面(102)等的螺旋生长及[010]晶带等的层生长现象。提出黑钨矿晶体的螺—层混合生长概念。The paper discusses the hydrothermal filling deposit of W-Bi-Mo quartz vein type and the vertical reverse zoning distribution of wolframite-bismuthinite- molybdenite mineral group .More detail studies of both macro -shape and micromorphological characteristics of wolframite crystals with goniometer and differential interference contrast (DIC) microscope are made . Several DIC photos served as criteria to the spiral -layer combined growth mechanism of wolframite .
