  • The analysis of sediment source has vital significance to the sedimentary area, reservoir characteristics and tectonic evolution. Based on the analysis of detrital composition, lithic type, heavy mineral assemblage, cathode luminescence, REE and seismic data, the provenance of Eboliang region in Qaidam Basin during the Paleogene has been specifically studied. The provenance of Eboliang No.Ⅰ structure mainly comes from the Altyn Tagh Mountain in the north. The Dongping structure belt in the west and Eboliang No.Ⅰ structure have relatively independent provenance. Eboliang No.Ⅱ structure is in mixed provenance area, which is influenced by two source directions. The main provenance is from the Altyn Tagh Mountain in the north through Eboliang No.Ⅰ structure. One of the other is from Xiaosaishiteng Mountain in the northeast of the study area through Lenghu No. 3, 4 and 5 structures. Provenance of Eboliang No.Ⅲ structure mainly comes from Saishiteng Mountain in northeast of study area through Lenghu No.6 and Lenghu No.7 structures without the influence by ancient Yuka largh fluvial-dominated delta from Nanbaxian direction.

Abstract: The analysis of sediment source has vital significance to the sedimentary area, reservoir characteristics and tectonic evolution. Based on the analysis of detrital composition, lithic type, heavy mineral assemblage, cathode luminescence, REE and seismic data, the provenance of Eboliang region in Qaidam Basin during the Paleogene has been specifically studied. The provenance of Eboliang No.Ⅰ structure mainly comes from the Altyn Tagh Mountain in the north. The Dongping structure belt in the west and Eboliang No.Ⅰ structure have relatively independent provenance. Eboliang No.Ⅱ structure is in mixed provenance area, which is influenced by two source directions. The main provenance is from the Altyn Tagh Mountain in the north through Eboliang No.Ⅰ structure. One of the other is from Xiaosaishiteng Mountain in the northeast of the study area through Lenghu No. 3, 4 and 5 structures. Provenance of Eboliang No.Ⅲ structure mainly comes from Saishiteng Mountain in northeast of study area through Lenghu No.6 and Lenghu No.7 structures without the influence by ancient Yuka largh fluvial-dominated delta from Nanbaxian direction.
