滇东南都龙锡锌矿床是我国已发现的第三大锡石硫化物矿床,其矿化受岩体、层位、构造、变质等多种因素控制,矿床成因尚存在较大争议。为探讨该矿床的成矿过程,我们对采自都龙矿床曼家寨矿段的锡锌矿石样品,进行了黑云母组构学与Ar-Ar年代学研究。1黑云母组构学分析样品ZK7208-4#
The Du Long tin-zinc deposit in southeastern Yunnan is the third largest Cassiterite deposit discovered in China. Its mineralization is controlled by many factors such as rock mass, bedding position, tectonics and metamorphism, and the genesis of the deposit remains controversial. In order to discuss the metallogenic process of this deposit, we studied the biotite structure and Ar-Ar chronology on the Sn-Zn ore samples taken from the Manjiazhai ore section of the Du Long deposit. 1 Biotite Structural Analysis Samples ZK7208-4 #
