摘　　要：通过分析黔西南高砷煤的元素地球化学特征,探索高砷煤中微量元素、稀土元素的地球化学行为,从而揭示了高砷煤的形成机理。分析表明,高砷煤与非高砷煤在微量元素含量方面存在较大差异,金、汞、铊矿石与龙潭煤系中的砷具有同源性,龙潭煤系页岩与峨眉山玄武岩在稀土元素组成上具有继承性。A research on geochemistry of the elements and the geochemistry behavior of REE and trace elements in high - As coal reveal that the formation mechanism of high - As coal is complex in southwestern Guizhou. The analyses indicate that high - As coal differ from the opposite in trace elements content distinctively. The arsenic in the coal - bearing rock series has the same origin with the Au, Hg and Tl ores and the shale in the coal -bearing rock series have inheritance against the basalt of the Emeishan Formation.
