摘要
本文在分析采集于西南某水电站PD1 6硐壁裂缝中不同位置的方解石形成年代以及碳氧同位素的基础上 ,结合坝区具体的水文地质情况 。
Based on the measurement of the formation age,and the carbon and oxygen isotope composition of calcite collected at different sites of fissures in tunnel PD?16 at a dam area,southwesten China,and combining specific hydrogeologic conditions of the dam area,authors have determined the period of karst development in the studied stream area,and paleoclimatic conditions at that time
