Braided river delta is an important reservoir type in continental sedimentary basins and the potential exploration target for the future.Core

log

and geophysical data indicate that the braided river delta in the Jurassic Sangonghe Formation of Junggar basin was deposited in an environment with gentle slope and shallow water.As a result of continuous progradation from the north to the center of the basin

arenaceous-conglomeritic deposits in the delta showed typical progradational seismic reflectance signatures

large cross bedding

and non-continuous positive rhythm.Its characteristics of sedimentary subfacies and microfacies as well as the favorable areas for exploration of lithologic traps are also discussed in this paper.
