摘要
内蒙古渣尔泰山群和白云鄂博群是一套陆源碎屑岩、泥页岩、碳酸盐岩,地层中Pt、Pd的含量与原岩中泥质、有机碳、有机质的含量有关。其中渣尔泰山群中的阿古鲁沟组炭质板岩、增隆昌组硅质炭质板岩为含Pt、Pd最佳层位(岩性),白云鄂博群中的比鲁特组千枚状板岩也为含Pt、Pd的最佳层位(岩性)。通过研究Pt、Pd的富集状况、存在形式、矿物学特征等,可查明渣尔泰山群、白云鄂博群中的含矿层位,以达到寻找铂、钯矿床的目的。
The rocks of the Zhaertaishan and Bayan Obo groups are composed of a suite of terrigenocs classic rocks, and carbonate rocks. The contents of Pt and Pd in the strata are associated with the contents of muddy, organic carbon and organic matter in original rocks. Of these rocks, carbonaceous slate in the Agulugou Formation and siliceous-carbonaceous slate in Zenglongchang Formation of the Zhaertaishan Group and phyllitic slate in the Bilute Formation of the Bayan Obo Group are the best horizons bearing Pt and Pd. The ore horizons in the Zhaertaishan and Bayan Obo groups may be ascertained by studying the concentrations, modes of occurrence and mineralogical characteristics and then the aim of looking for Pt and Pd deposits can be realized.
