Giant karst sinkhole cluster disvovered


9 Dec

An international team of scientists announced last November the discovery of a group of 19 dolines - cavities formed in calcareous regions by successive slumps of rock - interconnected through an underground river.


The complex is located in the Guangxi Autonomous Region of South China and is described as one of the largest groups of this type of limestone cavity discovered to date. Most of the sinkholes have a volume of over 1 million cubic meters and their original vetation, undisturbed from human activity.


According to the group's spokesman Jiang Zhongcheng, the study of this complex will bring important contributions to the development of the theory of evolution of dolines.
