There is Wenchang Formation in Panyu Low Uplift of Pearl River Mouth Basin, and fault activity has an important influence on sedimentation and distribution of sedimentary facies of Wenchang Formation. Based on fault activity rate method, activity characteristic of fault controlled in Wenchang Formation were analyzed quantificationally; combined with sedimentation rate analysis, activity intensity of fault controlled was calculated, and the correlation of fracture type and distribution of sedimentary facies was discussed. The results showed that fault controlled the deposition of middle deep lacustrine facies when activity rate was more than 100 m·Ma^-1; fault controlled the margin of deposition of middle deep lacustrine facies or delta facies and coastal shallow-lake facies when activity rate was less than 100 m·Ma^-1.
