Calculations show that times on the order of 3,000 to 10,000 years are needed to enlarge a fracture from an initial width of 10 to 50 micrometres to pencil-sized openings five to 10 millimetres wide.

Webb2 jan. 2024 · Kelly Hill Caves is a ‘karst’ cave system, a landscape formed by the dissolution of soluble rock such as limestone (calcium carbonate or calcite). As rainwater soaks through the soil, it seeps into the soft limestone and begins to dissolve it. An underground stream forms a small wet cave. WebbKarst is a distinctive type of landscape or topography that commonly occurs where carbonate strata (limestones and dolostones) are at the surface. Slightly acidic rainwater and water in the soil slowly percolate through fractures, dissolving the rock and creating sinkholes, caves, and many other features that characterize karst.
