Limestone Limestone is a SEDIMENTARY ROCK largely or wholly composed of calcium carbonate (CaCO 3).Carbonate rocks, and in some cases marble, the metamorphosed near-equivalent of limestone, are important to the CONSTRUCTION INDUSTRY as building stone and aggregate, and as the primary component of portland CEMENT and lime.

Additionally, quartz crystals formed inside igneous rocks also offer an onion shape, meaning these crystals come with layers and layers of molecules hardened into crystals. These outer layers take time to form, and you can see a significant difference in the color of different interior and exterior layers of a quartz crystal found inside a rock.Then, after the rock had lithified, becoming solid rock of limestone interbedded with shale, it experienced metamorphism, likely associated with continental collision. Continental collisions generally cause high heat and pressure to occur and could have formed both the marble and slate in a single event.

Limestone is a sedimentary rock, forming as small particles accumulate on a surface and cement into a solid mass over time. This rock is made from calcium carbonate (CaCO 3 ). You can identify limestone by particular physical characteristics, like the granular texture it forms from pieces of animal shells in the rock.Shale is a fine-grained sedimentary rock that forms from the compaction of silt and clay-size mineral particles that we commonly call "mud." This composition places shale in a category of sedimentary rocks known as " mudstones ." Shale is distinguished from other mudstones because it is fissile and laminated.

Fractures of set " d" are extension fractures that formed during unloading when the orientation of σ 3 became vertical in the rock-squeezing apparatus.

Limestone can also form from the evaporation of water in caves and other confined spaces. Parent Rock (Protolith): The original rock from which the metamorphic rock formed is considered in its classification. Knowing the parent rock provides insights into the geological history and the conditions of metamorphism. For example, shale can be the parent rock for slate, and limestone can be the parent rock for marble. Grade of Metamorphism:
