中文摘要：

沉积物元素地球化学特征是盆地沉积环境变化的响应。本文根据元素Ti、Mn、Li、Cr、Co、Ni、Cu、Zn、Ga、Cd、Ba、Pb、Sr、Rb、V的含量及Sr／Ba、Ni／Co、Ni／V、Cu／Zn、V／（V＋Ni）比值的变化规律，并结合有机地球化学特征，对抚顺盆地始新统计军屯组油页岩的沉积环境进行了分析。以Li、Ti为代表的外源元素，贫矿段的含量高于富矿段；而Sr、Ba等湖盆内化学沉积元素，富矿段的含量高于贫矿。Sr／Ba、V／（V＋Ni）、Ni／Co、Cu／Zn比值从贫矿段到富矿段呈现逐渐增大的趋势。富矿段有机质类型主要为Ⅰ型，而贫矿段主要为Ⅱ1、Ⅱ2。分析表明，本区油页岩富矿段形成于水体盐度较贫矿段高、还原性强的深湖环境，而贫矿段则形成于还原性较弱的半深湖一浅湖环境。

英文摘要：

Elemental geochemistry characteristics of sediment are responses to the depositional environment. Based on the contentsof the elementsincludingTi, Mn, Li, Cr, Co, Ni, Cu, Zn, Ga, Cd, Ba, Pb, Sr, Rb, V and elemental ratios such as Sr/Ba, Ni/Co, Ni/V, Cu/Zn, V/ （V＋ Ni） as well as organic geochemistry, the authors analyzed the depositional environment of the oil shale. Exogenic elements enriched in lowgrade section, such as Li and Ti; while endogenic elements, represented by Sr and Ba in low concentrations. Elemental ratios including Sr/Ba, V/ （V ＋ Ni）, Ni/Co, Cu/Zn gradually increased from low-grade section to high-grade section. Organic matter types are mainly Ⅰ type in high-grade section, while Ⅱ1 and Ⅱ2 types in low-grade section. These indices suggest that high-grade oil shale generates from deep lake with heavyish salinity and powerful reducibility and low-grade oil shale generates from semi-deep lake-mere with weak reducibility.
