通过对四川盆地龙潭组烃源岩全硫含量系统分析，研究了龙潭组烃源岩硫含量分布特征和控制因素，以及全硫含量对沉积环境的响应和指示意义。龙潭组不同岩性烃源岩全硫含量差异明显，泥页岩全硫含量高，灰岩硫含量则很低。烃源岩全硫含量（ TS）与其总有机碳含量（ TOC）、黄铁矿含量、干酪根碳同位素之间具有较好的正相关性。龙潭组烃源岩全硫含量和TOC/TS值对其沉积环境具有明显的响应和指示意义。川中、川东南等地区海陆交互相环境下形成的龙潭组烃源岩硫含量极高，TOC/TS值低；川东北地区台内凹陷、深水陆棚等环境下形成的烃源岩硫含量相对较高，TOC/TS值较高；盆地边缘城口、南江、石柱等地区碳酸盐台地、浅水陆棚等环境下形成的低有机质丰度灰岩烃源岩全硫含量低，而TOC/TS值高。

Based on the systematic analysis of Total Sulfur content ( TS) of source rock from the Upper Permian Longtan Formation(LTF)in Sichuan Basin,this paper studied the distribution feature of TS,its controlling factors as well as its re-sponses to and significance as a indicator for sedimentary environment .Shale source rock of LTF is rich in sulfur , but limestone is poor in sulfur .TS has positive correlations with TOC,pyrites content and δ13 C value of kerogen respectively . The TS and TOC/TS value of source rock have distinct responses to and significance as indicators for the sedimentary en -vironment .Source rocks of LTF in paralic facies in middle and southern Sichuan Basin has high TS and low TOC/TS value.Source rocks in intra-platform sag or deep-water shelf facies in northeastern Sichuan Basin has relatively higher TS and TOC/TS value.And limestone in carbonate platform or shallow-water carbonate shelf facies in Chengkou ,Nanjiang, Shizhu areas located at the edge of Sichuan Basin has low TS and high TOC/TS value.
