Analysis of Sedimentary Provenance of the Lower Segment of Paleogene Lower Ganchaigou Formation in Wunan-Lvcaotan Area, Qaidam Basin

Abstract

Abstract: On the basis of comprehensive researches of the driling, well logging, 3D seismic data and paleogeographic setting in this area, this paper proposes a new point of view that when E! deposited, Lvcan-1 well area was a developed area of Tiemulike provenance, while Nancan-2 well area was convergence site of Tiemulike, Kunlunshan and Dongchaishan provenances. Based on this recognition, the range of braided stream delta shaped from Tiemulike provenance can be extended toward the east.

Key words: Qaidam basin, deposit, sediment, provenance area, exploration
