| 摘 要： | 延边东部五道沟矿床内的钨矿体主要呈平行脉状赋存于华力西晚期蚀变花岗闪长岩中,与相邻的杨金沟大型钨矿相比,具有矿脉数量少、单脉厚度大和品位高的特点；矿石中金属矿物以白钨矿为主,呈团块状、粗粒浸染状、细脉状产于石英脉及碎裂蚀变围岩中,具有热液脉型矿床的矿化特征.主成矿阶段形成的粗粒白钨矿及石英颗粒中主要发育气液两相包裹体,...

| Abstract: | Tungsten mineralization of Wudaogou ore deposit occurs mainly in the Late Indosinian altered granodiorite as parallel scheelite-quartz veins.Compared with the adjacent Yangjingou ore deposit,some of the ore veins in Wudaogou are characterized by large thickness and high ore grade.As the most important ore mineral,the scheelite grains are distributed in massive,coarse-grained disseminated and veinlet forms in quartz veins and altered host rocks.Fluid inclusions are dominated by gas-liquid ones in both scheel... |
