四川黄龙沟天然水中的深源CO2与大规模的钙华沉积

Deep-source co_2 in natural waters and its role in extensive tufa deposition in the Huanglong ravines , sichuan , China

根据研究，钙华的形成是由于泉水中的CO2分压高于周围空气的CO2分压，CO2从水中逸出，因而导致碳酸钙发生过饱和并产生沉淀的结果。

According to previous researches , tufa results from the supersaturation of calcium carbonate , as the partial pressure of CO_2 in the spring water is higher than that in the atmosphere and CO_2 outgases from the water .
