Explanation

Also known as stalactite, stalagmite, stone pillar, stone flower, etc. Caldte in the form of stalactite. It is mostly found in limestone caves. In the limestone karst cave development area, when water rich in Ca (HCO3) 2 seeps from the cave roof, with the pressure decreasing, water evaporates, CO2 escapes, and Ca (HCO3) 2 in the water reaches supersaturation. CaCO3 keeps precipitation around the water drop outlet, and long conical calcareous sediments hanging from the cave roof will be deposited from the cave roof. If there is a lot of seepage water or it is not completely evaporated after precipitation at the top of the cave but drops on the bottom of the cave and then precipitation and grows upward, it looks like a bamboo shoot, which is called stalagmite. stalactite and stalagmite grow continuously and finally connect, which is called stone pillar. People also call stalactite goose tube stone. In addition to being an ornamental stone, stalactite is also a kind of traditional Chinese medicine. It is sweet in taste, warm in nature, has the function of supplementing qi and consolidating essence, and can brighten the eyes. In some areas of China, karst topography is developed. There are many limestone karst caves, forming many stalactite and some famous tourist attractions. For example, Guilin, Nanning, Hangzhou, Guizhou, Beijing and other places in Guangxi have very spectacular karst caves and stalactite landscapes.
