【摘要】 对采集于黔西南铊矿床(点)及其外围的31件矿物、矿石、蚀变围岩、未蚀变岩石进行了INAA分析。结果表明,样品中微量元素含量与玄武岩含量相差较大,与中酸性岩浆岩的含量非常相似,与在该地区地层中发现中酸性岩浆矿物相印证。更多还原

【Abstract】 INAA analysis was made on 31 samples of mineral,ore,altered wall rock and unaltered rock that were collected from Thallium deposit and its periphery.The results showed that the content of trace elements in samples had greater difference with basalt content and it was similar with the content of intermediate-acid magmatic rocks.This agreed well with the foundation of intermediate-acid magmatic rocks in the strata of this area.更多还原
