with calcite, it dissolves small amounts of the calcite and carries it away in a solution through cracks and pores in the rock, carving a bigger opening. Over a very long time, these holes can create caves. Limestone: gray sedimentary rock made of calcium carbonate.

Calcite CH1726 Wenshan China Mineral Specimen

Resembling a hook or perhaps an animal face, this remarkable waterformed calcite crystal is lustrous and gemmy, and totally pure and colorless. It is not a cave growth stalactite, but rather a true crystal, with real faces and a termination, formed in solution surely (rather than the way stalactites form later, slowly, as water drips down into a hole in these karst deposits in limestone in Southern China).
