中文摘要：

采用浓集化学光谱（C-OES）、X射线荧光光谱（XRF）、电感耦合等离子发射光谱（ICP-AES）等方法对滇东地区晚古生代及中、新生代21件含煤岩系全岩样品的22种微量元素及化学组分进行了测试分析，发现各时代含煤岩系均有不同程度Pt与Pd富集现象，且Pd／Pt＜1。其中，下石炭统万寿山组合煤岩系富集As，Pt，B，Au，Pd，V，Sb，U，Pb，W等元素；下二叠统梁山组合煤岩系富集B，Mo，As，Pt，U，W，Pb，Pd，V等元素；上二叠统宣威组合煤岩系富集Pt，Cu，Mo，Pd，As，V，Ag等元素；上三叠统须家河组合煤岩系富集As，B，Pb，Pt，Pd，U，W，Sb，Mo，Zn，Ag等元素；上新统茨营组褐煤富集Pt，As，Pb。结合沉积环境、火山活动等地质分析，宣威组合煤岩系中Pt-Pd-Cu等元素富集可能与二叠纪玄武岩（峨眉山玄武岩）有关。

英文摘要：

In this paper, C-OES, XRF and ICP-AES are used to determine twenty-two trace elements and contents in 21 whole rock samples from late Paleozoic, Mesozoic and Cenozoic coal-bearing series in the east of Yunnan. The result shows that platinum and palladium are to various degree enriched in different geological periodic coal-bearing series with Pd/Pt〈1. It can be seen that As-Pt-B-Au-Pd-V- Sb-U-Pb-W-Ag-Zn concentrate in the coal-bearing series of the Lower Carboniferous Wanshoushan Formation, B-Mo-As-Pt-U-W-Pb-Pd-V-Sb-Cr-Ag do in that of the Lower Permian Liangshan Formation, Pt-Cu-Mo-Pd-As-V-Ag-W-Pb do in that of the Upper Permian Xuanwei Formation, As-B- Pb-Pt-Pd-U-W-Sb-Mo-Zn-Ag-V do in that of the Upper Triassic Xujiahe Formation and Pt-As-Pb do in the lignite of the Pliocene Ciying Formation. With the geological analysis of sedimentary environments and volcanic activity, the paper concludes that higher contents of Pt, Pd and Cu in the coal-bearing series of the Xuanwei Formation tend to be related to the Permian basalt （Emeishan basalt）.
