Geomorphic features of quartz sandstone
Intermittent uplift of the earth's crust, the formation of the cave in the multi-layer structure, the three storey structure of the Huanglong Cave, marking the region since the end of the 4 period, at least, the manager of the three obvious intermittent movement of the earth's crust.
Platform conjugate vertical joints. For the formation of the road opened cave landform. The acid water that seeps into the ground, the slow dissolution of the fault in the long geological age. Is this the ants to head the spirit, dug out of the cave landscape with many twists and turns tenaciously in limestone.
Three Permian thick dolomitic limestone layer, is the material basis for the formation of the cave of Huanglong Cave, the most famous of the area and nine day hole are developed and Triassic limestone, the strata for continuous deposition, large thickness, a plurality of layers of chemical resistance ability of dolomite and dolomitic limestone, siltstone interlayer and clip, is conducive to the formation of multilayer structure of karst cave landscape.
