通过浮沉实验及脱灰实验对抚顺、龙口、茂名3种油页岩样中部分微量元素进行了赋存形态的研究。结果表明，浮沉实验所得微量元素的赋存状态结果与脱灰实验基本一致，抚顺、龙口、茂名3种油页岩中大部分微量元素以无机态赋存，但也有所区别，抚顺、龙口、茂名油页岩中的元素V、Mn、Zn、Sr、Mo、Ta以及抚顺油页岩中的Cr、Te，龙口油页岩中的Cd、Sn，茂名油页岩中的Cd、Sn、Pb，主要赋存于无机矿物中；茂名油页岩中的Cr、Te，抚顺油页岩中的Cd，龙口油页岩中的Pb有相对较多的比例富集于有机质部分；龙口、茂名油页岩中的元素Co，抚顺油页岩中的Co、Sn、Pb，更多地富集于黏土矿中，但也有少部分富集于有机质中。

The occurrences of trace elements in Fushun, Longkou and Maoming oil shale samples were determined using float-sink test and demineralization.The results of float sink test are consistent with that from demineralization.Most rt ace elements occur in inorganic mineral, but there are still some differences among the 3 oil shales.The trace elements of V, Mn, Zn, Sr, Mo, Ta, Cd are found in the samples.Cr, Te in Fushun, Cd, Sn in Longkou, and Cd, Sn, Pb in Maoming are primra ily assocai ted withm inear l matters.Th e trace elements of Cr, Te in Moa ming, Cd in Fushun, and Pb in Longkou oli shale samplesa er p irmarily associated with organic mineral.Part of Co, Sn, Pb in Fushun, Co in Longkou and Maoming oil shale samples are associated with organic mineral, while most of them are associated with clay mineral.
