摘要
贵州峨眉山玄武岩有关的矿床种类很多,有金,铜,锑,锰和稀土等许多金属矿床.这些矿床大部分产出的部位包括玄武岩下部界面,上部界面及喷发间期的浅变质熔结凝灰岩层中.这些层位不同层次不同程度发生了风化变质过程,出现了红土化,高岭土化,沸石化,硅化和沥青化,形成了一定规模的风化壳.本文结合贵州地区玄武岩的特征,对这些矿床的富集层位给予归纳总结,统称为风化壳型的矿床,并且对于赫章和威宁发现的两个稀土矿床进行对比分析.
The E＇ meishan basalt related with many ore deposit type, e.g. Au,Cu,Ti,Mn and many ore deposits in Guizhou Province. Ore deposits were controlled on the top part of basalt, or interbedded tuff, or base contact surface of basalt in Guizhou. These horizons and surfaces have different level varying degee and the decency deterioration process, and appeared laterization, Kleit, Zeolitization, Silicification and bituminization in a certain scale weathering crust. In this article, authors suggest that the concept of the weathering crust ore deposit from the characteristic of the E＇ meishan basalt, concentration of ore deposits in weathering crust. Additionally, authors study and analysis two rare earth ore deposits of Hezhang and Weining, west Guizhou Province.
