Gravity flow sedimentary characteristics and sedimentary model of the 1 member of the Tengger formation in Saihantala depression (Erlian Basin, China)
Based on core, well-logging and seismic data, the gravity flow characteristics and sedimentary model of the 1st member of the Tengger formation in the eastern steep slope belt of the Sai-4 tectonic belt in the Saihantala depression (Erlian Basin, China) have been systematically studied; further, the...

| description | Based on core, well-logging and seismic data, the gravity flow characteristics and sedimentary model of the 1st member of the Tengger formation in the eastern steep slope belt of the Sai-4 tectonic belt in the Saihantala depression (Erlian Basin, China) have been systematically studied; further, the sublacustrine fan sedimentary model in the study area has been established. The main types of gravity flow identified in the study area are sandy debris flow deposits and turbidity flow deposition. Affected by paleo-geomorphology, provenance and other factors, sublacustrine fans in the eastern steep slope zone are formed by gravity flows from different periods. The sublacustrine fan is divided into three subfacies: inner-fan, mid-fan and outer-fan. The subfacies can be subdivided into six types of microfacies: main channel, levee of main channel, distributary channel, inter-channel, levee of distributary channel and terminals. The formation of the sublacustrine fan is caused by steep slopes and triggered by earthquakes. The sedimentary model of the sublacustrine fan and its sedimentary characteristics provide a foundation for exploring and developing oil and gas in the study area. |
