석순, or "soksoon," refers to a type of natural rock formation found in caves, primarily composed of calcium carbonate. These formations are created by the slow deposition of minerals from dripping water over long periods. As water seeps through the ground, it picks up minerals and eventually deposits them when it reaches a cave, leading to the growth of these unique structures. 석순 is often associated with 석회암 caves, where the conditions are ideal for their formation. They can vary in size and shape, creating stunning visual displays within the cave environment. These formations are important for understanding geological processes and are often a highlight for visitors exploring 동굴 systems.
