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

Geofluids, 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.

Water‐Inrush Risk Assessment of Roof‐Confined Aquifer Strata Based on FAHP–RF Model in the Arid–Semiarid Ecotone: A Case Study of Zhuanlongwan Coal Mine

Geofluids, Volume 2026, Issue 1, 2026.
Water inrush poses a serious threat to the safety and sustainability of coal mining operations, particularly in arid–semiarid regions where confined aquifers overlie coal seams. Therefore, an accurate assessment of roof water inrush risk is essential to prevent water hazards on the roof.
