Shale is a laminated or fissile clastic sedimentary rock that composed of predominance of silt and clay other minerals , especially quartz and calcite. Characteristic properties of shale is breaks along thin laminae or parallel layering or bedding called fissility. It is most abundant sedimentary rock.When the two waters mixed, the H 2 S combined with the oxygen carried by the rainwater and formed sulfuric acid (H 2 SO 4). This acid dissolved the limestone along fractures and folds in the rock to form Carlsbad Cavern. This process left behind massive gypsum deposits, clay, and silt as evidence of how the cave was formed.

Limestone is primarily composed of dissolved calcium carbonate, often in the form of calcite. This composition gives limestone its characteristic durability and ability to withstand weathering. Sandstone, on the other hand, is composed mainly of sand-sized grains of mineral, rock, or organic material. Sedimentary rocks are formed on or near the Earth’s surface, in contrast to metamorphic and igneous rocks, which are formed deep within the Earth. The most important geological processes that … ….
