| Triassic Turbidity Current Deposit and Genetic Model of Yanchang Formation of Xifeng Oilfield, Ordos Basin |
| Triassic turbidity current deposits of Yanchang Formation well developed in the Xifeng oilfield, Ordos basin. According to the core,well-logging data and outcrop, efforts are made in this thesis to recognize turbidity current channel,pigtail turbidity current channel,layer turbidity current,trough turbidity current and slump turbidity current from strata. Based on the theory of sediment dynamics and mechanism of genetic of turbidity current, two kinds of genetic models of turbidity current are developed: the genetic model of flood turbidity current and the genetic model of slump turbidity current. Then the relationship between turbidity current deposits and tectonic condition is analyzed. This thesis puts forward suggestion that the tectonic setting controls the mode of space-time exhibition of turbidity current deposits. |
