  • Mixed sediments of lacustrine carbonate rocks and clastic rocks are developed in the Da'anzhai Member of Ziliujing Formation in Huilong area, western Sichuan. Based on the comprehensive analysis on field outcrops, drilling cores, well logging and microfabric, the sedimentary microfacies of mixed sediments of the study area was finely depicted. The results revealed that the Da'anzhai Member in Huilong area belonged to the lacustrine mixed sedimentary facies consisting of shore-shallow lake and semi-deep lake subfacies, which was further divided into five mixed sedimentary microfacies, including high-energy shelly beach, low-energy shelly beach, sandy shoal, shallow lake and semi-deep lake. Further more, based on the features of mixed sedimentary facies and the evolution process of the Da'anzhai Member in Huilong area in Jurassic Period, the origin and evolution pattern of mixed sediments in the study area was analyzed. It was concluded that the lacustrine mixed sediments in the study area were predominantly controlled by provenance supply and hydrodynamic condition and various type of mixed sediments were formed under the control of five mixed sedimentary microfacies.

Abstract: Mixed sediments of lacustrine carbonate rocks and clastic rocks are developed in the Da'anzhai Member of Ziliujing Formation in Huilong area, western Sichuan. Based on the comprehensive analysis on field outcrops, drilling cores, well logging and microfabric, the sedimentary microfacies of mixed sediments of the study area was finely depicted. The results revealed that the Da'anzhai Member in Huilong area belonged to the lacustrine mixed sedimentary facies consisting of shore-shallow lake and semi-deep lake subfacies, which was further divided into five mixed sedimentary microfacies, including high-energy shelly beach, low-energy shelly beach, sandy shoal, shallow lake and semi-deep lake. Further more, based on the features of mixed sedimentary facies and the evolution process of the Da'anzhai Member in Huilong area in Jurassic Period, the origin and evolution pattern of mixed sediments in the study area was analyzed. It was concluded that the lacustrine mixed sediments in the study area were predominantly controlled by provenance supply and hydrodynamic condition and various type of mixed sediments were formed under the control of five mixed sedimentary microfacies.
