摘　　要：采用微量元素和重矿物判别分析方法解决百昆仑山前长期未解决的红色哑地层划分对比问题。微量元素和重矿物与沉积环境及物源性质密切相关。不同时期，不同水系（物源区）的沉积岩具有不同的重矿物和微量元素特征。在西昆仑山前初步建立了３条微量元素和重矿物标准剖面，每条剖面均建立了划分组段的微量元素和重矿物两套判别函数。用以解决地面或井下未知层位样品的判别归属问题，经地面和井下验证取得初步成效。The discrimination of trace elements and heavy minerals is applied to solve the long-existing problems of the classification and correlation of puzzling red strata in the piedmont of West Kunlun. The trace elements and heavy minearls are closely related with sedimentary environment and source materials. Different time, different water system and different material source area result in different characters of heavy minerals and trace elementc.Three standard sections are primarily set up, with discrimination parameters of trace elements and heavy minerals.So it tells the ownership of samples of unknown horizons from surface or underground.A primary effect is so obtained for the testing of surface and underground samples.
