Organic matter types of core SB-01 from the Sanshui Basin were analyzed using organic petrology method and Rock-Eval pyrolysis. Based on organic petrology results, the organic matter is dominated by type Ⅱ(including type Ⅱ1 and type Ⅱ2), mostly type Ⅱ1. Type Ⅰ organic matter intermittently occurs at some intervals while Type Ⅲ organic matter is occasional in presence. Pyrolysis results show that the organic matter is of lower thermal maturity and the organic carbon loss could be ignored, as indicated by the lower Tmax values. Organic matter of Types Ⅰ, Ⅱ1 and Ⅱ2 was deposited under arid, drier and humid climate conditions, respectively.
