Abstract

Abstract

To examine the fine-grained gravity flow sedimentation of the Chang 7₃ submember in the Longdong area, Ordos basin, through observation of core and thin sections, XRD analysis, and trace elements analysis, the sedimentary characteristics and influencing factors of fine-grained gravity flow sedimentation were studied. 7 lithofacies assemblages were formed due to different depositional processes: the shale with lamina tuffaceous assemblage, the fine-grained turbidity currents to mud flow assemblage, the transitional flow to mud flow assemblage, the slump to debris flow to mud flow assemblage, the surge-like turbidity flow assemblage, the quasi-steady turbidity current assemblage, and the concentrated density flow assemblage. The development of fine-grained gravity flow is mostly controlled by tectonic activities, paleo-climate change, and paleo-topography of the lacustrine basin. Tectonic activities are the key factors in inducing the development of slump-triggered fine-grained gravity flow sedimentation, while flood events promote the development of flood-triggered fine-grained gravity flow sedimentation. The characteristics of the paleogeomorphology have a significant control effect on the distribution of fine-grained gravity flow sedimentation, the gradient of the slope significantly influences the depositional characteristics of slump-triggered fine-grained gravity flows.
