  • Sedimentary Rocks - Geology

    Clastic sedimentary rocks such as breccia, conglomerate, sandstone, siltstone, and shale are formed from mechanical weathering debris. Chemical sedimentary rocks, such as rock salt, iron ore, chert, flint, some dolomites, and some limestones, form when dissolved materials precipitate from solution. Organic sedimentary rocks such as coal, some ...

  • Igneous, Sedimentary and Metamorphic Rocks

    A rock is a solid cumulative of minerals located in the earth's lithosphere. They are generally classified into igneous, sedimentary, and metamorphic rocks, on the basis of their mineral, chemical, and textural composition.

  • 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 .

  • Chemical Sedimentary Rocks - CliffsNotes

    Limestones. The most common chemical sedimentary rock is limestone. Composed mostly of the mineral calcite (CaCO 3), limestones are usually formed by biochemical processes in shallow seawater. Coral and algae are especially important limestone builders. Oolitic limestones form in ocean shallows from the accumulation of oolites, sand‐sized spheres of chemically precipitated calcite that ...
