They are generally very delicate with diameters less than 1 mm. They can grow horizontally or curl upwards to form dendritic features. They are generally believed to be formed in connection with a process in which the calcium carbonate saturated water seeps slowly from cave cracks or the capillary pores of stalactites at such a slow rate that the effect of gravity is less than that of the surface tension, and subsequently the stone branches can grow haphazardly in every direction. Their formation is also believed to be related to the wind and microbial effects in the cave. Bama Crystal Palace, Guangxi Province, contains many stone branches.
