The Hongsanhanyihao and Niubiziliang area developed two provenance systems which controlled the fan delta and shallow lake sedimentary system in western Qaidam basin. By means of the core observation, the sandstone framework component character,the type of the heavy mineral and their assemblages features, several wells are joined together to compare the sand, and analyze the paleo-geographic settings of Lulehe formation in the Honganhanyihao and Niubiziliang area. The provenance system and sedimentary system are studied comprehensively. The results show that this area developed fan delta in the shallow lake which is controlled by the Hongsanhanyihao sedimentary provenance and the west valley of the Niubiziliang sedimentary provenance in the time of the Lulehe formation. The Hongsanhanyihao sedimentary provenance is consisted of three embranchments: firstly, Jiandingshan water system, which mainly flowed southwest into Jiandingshan area by the first high point of the Hongsanhanyihao, secondly, the Changweiliang water system, which mainly flowed south into Changweiliang area by the third high point of the Hongsanhanyihao, and thirdly, Jianbei water system, which mainly flowed southeast into the north of Jianshan area by the fifth high point of the Hongsanhanyihao. And, the west valley of the Niubiziliang sedimentary provenance mainly flowed southeast to the east of the Jianshan area.
