摘要
四川兴文喀斯特包括小岩湾天坑和大岩湾退化天坑,以及猪槽井洞穴系统中潜在的洞穴崩塌大厅。这3个地方似乎可以说明天坑的演化顺序,即天坑从多重洞穴崩塌,到最后退化成大型漏斗的过程。
The karst of Xingwen, China, contains the Xiaoyanwan tiankeng, alongside the degraded tiankeng of Dayanwan and also the potential collapse chambers in the Zhucaojing cave system. These three sites ap- pear to represent an evolutionary sequence, whereby a tiankeng develops from multiple cave collapses, and subsequently degrades to the profile of a large doline.
