Abstract The Oligocene Zhuhai Formation is one of the main reservoirs in the Pearl River Mouth Basin(PRMB), northern South China Sea. However,the key issues such as the provenance location and sediment transport path are still controversial. Zircon fission track(ZFT)and apatite fission track(AFT)thermochronology are carried out for sandstone samples from the upper Zhuhai Formation of three key wells in different structural units of PRMB to analyze the provenances of Zhuhai Formation. The ZFT and AFT age components of Well XJ28 in Xijiang sag are similar to those of Well LW3 in Baiyun sag,and include the ZFT age components of Late Triassic. Furthermore, the main age components of ZFT and AFT are Cretaceous and Paleocene respectively. In contrast,the ZFT and AFT age components of Well LF7 are obviously younger than those of the first two wells and the main ZFT age component of Well LF7 is Paleocene. The ZFT and AFT age components of those three wells indicate the provenance of the upper Zhuhai Formation is mainly from the South China block in the north of PRMB,but there are obvious provenance differences between the western and the eastern of the basin. The provenance characteristics of Wells XJ28 and LW3 in the western basin are generally consistent,both of which are supplied by the ancient Zhujiang River water system. The provenance is mainly the Mesozoic granite in the ancient Zhujiang River drainage area,and also includes the Mesozoic sedimentary basin in the hinterland of South China block. The provenance of Well LF7 in the eastern basin is mainly the coastal Mesozoic granite in the north of Lufeng sag. The provenance composition is relatively simple and the sediment transport distance is relatively short.
