When did the Ancient Fen River Dry up? Timing and Mechanisms of River Abandonment in the Yuncheng Basin (Southern North China Craton) Based on Sedimentary and Paleoclimatic Evidence

Key Points

• River abandonment occurred due to major climatic changes, impacting sediment deposition processes.
• Key findings indicate sedimentary and paleoclimatic evidence supports a gradual drying trend over centuries.
• Analysis of geologic samples identified changes in river dynamics linked to climatic shifts in the region.
• Implications highlight the need for further studies on ancient waterways and their responses to climate variations.
