查询词典 basic carbonates

When the underground water percolates through a soluble rock sequence along its fissure it will dissolve large amount of calcium carbonates and seep out from the sidewalls and the roof. Due to the changes in temperature and pressure, water evaporated and carbon dioxide escaped and the dissolved calcium carbonate in the water precipitated in various forms.

地下水沿着可溶性岩石和裂隙渗透，溶解了岩石中的较多的碳酸钙，通过洞顶或洞壁滴流出来，因为温度、压力的改变，水的蒸发，二氧化碳散失，使溶解在水中的碳酸钙沉淀下来形成各种形态。
