摘要
To better understand the growth mechanism of the stalagmite,cave monitoring should be performed. Nanjing Hulu Cave is well known for its last glacial climate record from the stalagmites. In this paper, the authors made monthly in-situ monitoring of hydrogeochemistry at Hulu Cave and another comparative cave, Penglaixian Cave in Anhui Province which locates under the same climate conditions with Hulu Cave and possesses a large number of modern secondary carbonate deposits. To detect the possible causes of loss of active speleothem in Hulu Cave and the different conditions controlling the modern secondary carbonate deposition in the two caves, seven drip sites were selected, and each of them has a stalagmite at the bottom. The results show that, except the contents of anions are dramatically different, the other indexes in two caves are similar.
