👉 Cave fluids, also known as speleothems' formation fluids, are mineral-rich water that seeps through the ground and into caves. These waters originate from rain or snowmelt that percolates through soil and rock, dissolving minerals like calcium carbonate. As the water travels deeper into the cave system, it encounters lower temperatures and reduced pressure, causing the dissolved minerals to precipitate out and crystallize, forming various cave formations such as stalactites, stalagmites, and flowstones. Over time, these mineral deposits build up, creating intricate and diverse geological structures that are characteristic of cave environments.
