Hot spring deposits on a cliff face: A case study from Jifei, Yunnan Province, China
Jones, Brian1; Peng, Xiaotong2

A cliff face in the Jifei karst area, southwest China, is covered by a spectacular succession of precipitates that formed from the hot spring water that once flowed down its surface. This layered succession is formed of aragonite layers that are formed largely of "fountain dendrites", calcite layers that are formed mostly of "cone dendrites", and microlaminated layers that contain numerous microbes and extracellular polymeric substances (EPS). Many of the aragonite crystals are hollow due to preferential dissolution of their cores. The calcite cone dendrites are commonly covered with biofilms, reticulate Si-Mg coatings, and other precipitates. The microbial layers include dodecahedral calcite crystals and accessory minerals that include opal-A, amorphous Si-Mg coatings, trona, barite, potassium sulfate crystals, mirabillite, and gaylussite. Interpretation of the 8180(calcite) and delta O-18((aragonite)) indicates precipitation from water with a temperature of 54 to 66 degrees C. The active hot spring at the top of the cliff presently ejects water at a temperature of 65 degrees C.
