大型帐篷构造对贵州天星桥喀斯特石林形成演化的控制作用
Control Action of Large Tepee Structure to Formation and Evolution of Karst Stone Forest in Tianxingqiao, Guizhou
摘要
Abstract
In Huangguoshu-Tianxingqiao area, Anshun, Guizhou, the dolomite of the Lower Triassic Anshun Formation was widely exposed, and a contiguous Water Stone Forest was developed. The Anshun Formation was developed on the transitional zone between the Triassic deep - sea basin and platform margin where marine transgression happened frequently, and large tepee structures were well developed on the exposed surface of the ancient coastal. The feature of exposed zone in ancient carbonate rocks, firstly, resulted in cracks and holes in rocks, which was highly conducive to infiltration of precipitation and groundwater' s storage and transport; and secondly, it resulted in weak structural dense rock so that rock mechanical strength decreased and joint fissures emerged easily under the action of tectonic stress, then a large number of channels were opened up for the precipitation infiltration and groundwater migration. In this paper, combining field visits and previous data, writers attempt to study the control action of the large tepee structure to the formation and evolution of karst stone forest in this area.关键词
