Controls of Base‐Level Cycles on the Sedimentary Architecture of Subaqueous Distributary Channels in a Lacustrine Delta: A Case Study From the Chang 8 Member, Ordos Basin

open access: yesGeofluids, Volume 2026, Issue 1, 2026.
Base‐level cycles serve as a crucial reference for the stratigraphic sedimentology. In lacustrine basins, high‐frequency base‐level changes contribute to significant diversity and complexity in sequences and sedimentary infilling. The sequences′ infill and facies distribution in lacustrine basins differ greatly from marine deposits.
