High Mountain and Frigid Karst Calcareous Pool Landscape
Reference work entry
This is a landform composed of colourful calcareous pools formed by spring precipitation in an alpine region. Jiuzhaigou in Sichuan Province is a typical representative. The Jiuzhaigou region is located at elevations greater than 3,000 m, where the average annual temperature is lower than 5 °C. Calcareous springs run down glacial valleys. Calcium precipitation from these springs has created a series of stone embankments that pool water of various colours, forming a landform of magnificent calcareous pool clusters. This site is now a national geopark and World Natural Heritage Site (Figs. 10 and 11).
