Limestone rock formation.
In general, compared to intact rock, a rock mass has reduced tensile strength (almost zero), and reduced shear strength especi ally along discontinuity planes. Furthermore, if a rock mass is cut by directional joint sets , the rock mass strength is anisotropic. Rock mass strength is scale dependent and varies with the volume of rock under ...

Molds are the openings left behind when minerals dissolve or when dead organisms decay. The material that subsequently fills a mold is a cast. Fossils are the most common kind of cast, and casts of easily dissolved minerals like halite are also known.

Jun 8, 2017 · In the most dramatic instances, karst mountains are created when acidic waterflow wears down limestone bedrock, creating cracks in the bedrock surface. Once cracks are formed, water is then able to flow more quickly and with greater force, creating underground drainage paths, which, in turn, lead to greater erosion.
