摘要
从气体成分、泉口出露地质特征、CO2动态变化规律等,对黄龙钙华的热成因论进行了讨论,认为黄龙地区不具备喷出幔源气体的地质结构。黄龙钙华是地壳表层地质作用高寒岩溶形成的产物,即冷成因。
This paper discusses hydrothermal genesis of the Huanglong travertine based on gas competent, dynamic change in CO2 and geological features of springs, and believes there is no geological structure related to the extrusion of mantle - derived gas. Therefore, the Huanglong travertine resulted from karstification in high and cold area on crust surface.
