摘要
白干湖钨锡矿田矿床类型属构造导控的高温热液型,矿化体几何形状取决于导控构造及容矿岩石的性质.该矿床容矿岩石有绢云石英片岩、石英透闪石岩、变质辉长岩、蚀变花岗岩等区内所有岩石类型.矿化是以均匀的微细脉浸染为主,矿化岩石与同类型未矿化岩石特征差别无几,矿化期交代作用十分微弱.矿石类型属于微细脉浸染及富细脉型.矿化体模型是在基本了解矿床地质特征,成控规律以及地表主要矿体形态数据基础上拟建的.理论上,矿化体是以导矿构造为骨架的简化板状矿化体,与易矿化岩层贯通所形成的似层状矿化体构成的复合体.这种复合体即使在高精度矿产勘查过程中也不能保证取得相对准确的数据.因此,准确识别矿化体性质十分重要.
Abstract： The deposit type of the Baiganhu tungsten and tin ore field belongs to structural controlled high-temperature hydrothermal deposit. The geometric figure of mineralized body depends on the character of the controlled structure and host rock. The host rocks of this deposit include sericite quartz schist, .quartz sanidine rock, metamorphism gabbro and granite. The mineralization is mainly the dissemination of the even thin dike.There is few differences between the mineralized rocks and the nonmineralized rocks. The replacement of mineralization phase is faint.The type of the mineral is thin dissemination hydridization and rich thin dikerock. The mineralized body model is established on the understanding of mineral character, mineral law and the data of geometric figure of ore body. In all, the correct recognition of the character of ore body is very important.
