摘要
类乌齐锡矿床是西藏近年来正在进行找矿评价的首批锡矿床。本文对矿区锡石的形态特点、物理光学性质、化学成分、红外光谱、晶体结构以及矿物组合等标型特征进行了系统的观察测试及研究。在此基础上,与同一成矿带的滇西某些锡矿床锡石标型特征作了对比,从矿物学研究角度,对本矿床的成因提供了与花岗岩类有关的气成—热液成矿的信息。
This paper deals with the form features,physical-optical properties,chemical composition, infrared spectra, crystal structures,mineral assemblages of cassiterite of Leiwuqi tin deposits, Xizang. Comparcd with typomorphic characteristics of cassiterite of tin deposits in Western Yunnan, the paper also points out the differences and similrarities as well as the possible origin types of Leiwuqi tin deposits.
