Calcareous Conglomerate Karst Landscape
Reference work entry
This is a unique type of karst landform that develops in calcareous conglomerates, such as the Longmen Mountain landform in Anxian, Sichuan Province, where dissolution is rare and has caused the formation of peak clusters. Another example is Luofu Mountain, which also has a formation of stone forests, conglomerate caves and subterranean rivers in the lower strata. The Longmen conglomerate cave is located in Lushan County in Ya’an City, Sichuan Province. It is more than 20 km long, and 13.2 km have been surveyed. Its vertical depth is 356 m, and it is the longest and deepest maze-type cave to be discovered in China. Part of it has been opened to tourists (Fig. 1).
