The groundwater that percolates through the cracks in the cave contains calcium and bicarbonate from the dissolution of limestone As the water drips from the cave's ceiling, CO 2 gas is released and a small amount of calcite crystallizes where the drop is attached to the ceiling More CO 2 is lost from the water when the drop hits the floor, causing more calcite to precipitate
