According　to　the　outdoor　profile　survey,　collection　of　Permian-Triassic　marine　source　rock　samples　in　systematic,　and　the　organic　matter　abundance,　type,　maturity　and　chloroform　bitumen　＂A＂,　also　study　the　relationship　among　them,　the　results　show　that:　TOC,　S1+S2,　chloroform　bitumen　＂A＂　have　a　good　correlation,　S1+S2　and　chloroform　bitumen　＂A＂　range　of　marine　carbonates　rocks　and　mudstone　are　stable,the　value　of　mudstones　are　better　than　carbonates　rock;　Evaluation　of　P2c,　T2d　carbonates　are　favorable　district　two　sets　of　source　rocks.　Make　use　of　trace　elements　and　rare　earth　elements　of　mudstone,　trace　elements　of　sandstone,　the　results　show　that　the　marine　of　source　rock　ancient　water　deposited　environment　were　anaerobic　and　hypoxia,　environment　from　oxidizing　to　restore　continuous　transition　from　Permian　to　Triassic.　The　wholly　palaeosalinity　over　all　lower,　shallow　water,　influenced　more　by　land　than　sea　from　Permian　to　Triassic.　Provenance　from　source　area　under　oxidizing　environment,　far　away　from　the　basin.　©　2014　CAFET-INNOVA　TECHNICAL　SOCIETY.
