广东一废弃水库出现“冰川遗迹”？地质专家回应

Core Viewpoint - A unique geological feature resembling glacial remnants has been discovered in a dried-up reservoir in Yuxing Village, Heyuan City, sparking interest among geology enthusiasts and local residents [1][3]. Group 1: Discovery Details - The discovery was made by a local geology enthusiast, who found a large area of circular depressions in the reservoir bed, measuring nearly 100 square meters, with depths reaching several tens of centimeters [3]. - The depressions are characterized by smooth inner walls and clear signs of water erosion, leading to speculation about their origins [3]. Group 2: Geological Significance - Initial public speculation suggests that the depressions may be glacial features, specifically "ice basins," which are significant for understanding ancient climatic conditions [6]. - A local geological expert indicated that confirming the nature of these depressions requires comprehensive analysis of regional paleoclimate, rock composition, and structural background [9]. - If confirmed as an ice basin group, this discovery could provide important samples for research on the ancient environment of South China [9].
