Limestone - Wikipedia

Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and molluscs.Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO 3) 2.

Limestone - Sedimentary rocks

Limestone is a very common sedimentary rock consisting of calcium carbonate (more than 50%). It is the most common non-siliciclastic (sandstone and shale are common siliciclastic rocks) sedimentary rock.Limestones are rocks that are composed of mostly calcium carbonate (minerals calcite or aragonite). Carbonate rocks where the dominant carbonate is dolomite (calcium magnesium …

How Does Marble Form? | Reference.com

Marble is a soft metamorphic rock that forms at the edges of tectonic plates, where limestone is exposed to regional metamorphism. The heat and pressure of the metamorphic zone force calcite inside the limestone to recrystallize and merge into the classic marble consistency. Marble begins as limestone near the edges of tectonic plates.

A Very Simple Metamorphic Classification

Compositionally simple sedimentary rocks, such as quartz sandstone and limestone (calcite) do not change composition with metamorphism - their chemistry is too simple. Quartz remains quartz, and calcite remains calcite. The rocks do recrystallize, though, forming granular rocks with fused grains; the rocks quartzite and marble.
