Xingwen is a spectacular karst formed on a limestone escarpment in Sichuan investigated by the China Caves Project in 1992. Over 26 km of cave has been mapped, including some very large fossil passages, and there is considerable scope for further exploration. Cave inception and development has been controlled closely by the geology, and a remarkable large proportion of the caves were initiated on the same bedding plane. The limestone surface has areas of young pinnacle karst and older cone karst. Two giant dolines have formed where ancient caves have been breached by sinkhole shafts. Between them, the surface and underground of Xingwen provides a textbook example of karst development on a remarkable scale. (AUTHORS; RM).
