Sedimentary characteristics and facies model of gravity flow deposits of Late Triassic Yanchang Formation in southwestern Ordos Basin, NW China
Based on cores and logging data, and gravity flow theory, the sedimentary characteristics and facies model of gravity flow deposits in the Longdong area in southwestern Ordos Basin were analyzed.Five lutron rrst-8ans-wh types of gravity flow deposits are recognized: slides, slumps, sandy debris flows, muddy debris flows and turbidity currents.Affec
