 In order to probe into abnormal geothermal’s influence on hydrocarbon-generation, the authors collected eight source rock samples (W008-W015) from the black mudstone series of strata of Carboniferous upper Haerjiawu group on the south side of the diabase intrusion of the East Daheishan Profile in the Santanghu Basin, whose distance to the diabase rock is 20 cm, 50 cm, 100 cm, 180 cm, 300 cm, 500 cm, 1 000 cm, and 1 700 cm, respectively. From the analysis, the authors conclude that the overall maturity of this source rock is rather high, and near the diabase intrusion with the distance range of 1～1.8 m, its maturity index has the trend of exceptional increase which shows the source rocks directly exposed to the intrusive rocks has a relative smaller scope of baking effect which is less than about 1.8 m.
