生物标志化合物在黔西南晴隆锑矿床成因分析中的应用

Significance of Biomarker Trace in Ore Fluids to the Genesis of the Qinglong Sb Deposit, Southwest Guizhou

来自相同有机母源的有机物具有相同的生物标志化合物组成特征,被誉为"地球化学化石"或"生物分子化石",被广泛应用于油气勘探,但在固体矿产方面的应用并不多见。通过对黔西南晴隆锑矿床中与锑矿密切共生的萤石进行有机包裹体生物标志化合物特征分析,与相邻的右江盆地进行生物标志化合物特征对比,认为晴隆锑矿床的成矿流体来源于右江盆地上二叠统邻好组,经古岩溶面横向运移至晴隆聚集成矿,成因为燕山期热液充填交代成矿。

Biomarker trace known as chemical fossil and biomolecule fossil of the Earth have been extensively applied only to the oil and gas exploration, up to now. The organic matter in ore fluids is known as biomarker trace. Correlation of biomarkers of the organic inclusion in fluorite from the Qinglong Sb deposit, southwest Guizhou with those in mudstone in the Youjiang basin indicates that the ore fluids might come from the Upper Permian Linghao Formation in the Youjiang basin.
