  2. Limestone - Wikipedia

    en.wikipedia.org/wiki/Limestone

    Limestones also form in freshwater environments. [69] These limestones are not unlike marine limestone, but have a lower diversity of organisms and a greater fraction of silica and clay minerals characteristic of marls. The Green River Formation is an example of a prominent freshwater sedimentary formation containing numerous limestone beds. [70]

  3. List of types of limestone - Wikipedia

    en.wikipedia.org/wiki/List_of_types_of_limestone

    Travertine – Form of limestone deposited by mineral springs Tufa – Porous limestone rock formed when carbonate minerals precipitate out of ambient temperature water The following sections include both formal stratigraphic unit names and less formal designations, although are these are not differentiated.

  4. Lime (material) - Wikipedia

    en.wikipedia.org/wiki/Lime_(material)

    Lime is an inorganic material composed primarily of calcium oxides and hydroxides. It is also the name for calcium oxide which is used as an industrial mineral and is made by heating calcium carbonate in a kiln. Calcium oxide can occur as a product of coal-seam fires and in altered limestone xenoliths in volcanic ejecta. [1]

  5. Carbonate rock - Wikipedia

    en.wikipedia.org/wiki/Carbonate_rock

    Limestone is the most common carbonate rock [3] and is a sedimentary rock made of calcium carbonate with two main polymorphs: calcite and aragonite.While the chemical composition of these two minerals is the same, their physical properties differ significantly due to their different crystalline form.

  6. Shelly limestone - Wikipedia

    en.wikipedia.org/wiki/Shelly_limestone

    In detail, shelly limestones are formed when rocks containing different minerals get weathered down then get transported to a standing body of water. From here organisms that precipitate carbon, phosphate, and silicate materials (which forms the rock's shelly texture) combine with the minerals and go through a process called deposition, where ...

  7. Conglomerate (geology) - Wikipedia

    en.wikipedia.org/wiki/Conglomerate_(geology)

    A conglomerate or any clastic sedimentary rock that consists of a single rock or mineral is known as either a monomict, monomictic, oligomict, or oligomictic conglomerate. If the conglomerate consists of two or more different types of rocks, minerals, or combination of both, it is known as either a polymict or polymictic conglomerate.

  8. Agricultural lime - Wikipedia

    en.wikipedia.org/wiki/Agricultural_lime

    Because each molecule of magnesium carbonate is lighter than calcium carbonate, limestones containing magnesium carbonate can have a CCE greater than 100 percent. [12] Because the acids in soil are relatively weak, agricultural limestones must be ground to a small particle size to be effective.

  9. Lithographic limestone - Wikipedia

    en.wikipedia.org/wiki/Lithographic_limestone

    The original source for lithographic limestone was the Solnhofen Limestone, named after the quarries of Solnhofen where it was first found. This is a late Jurassic deposit, part of a deposit of plattenkalk (a very fine-grained limestone that splits into thin plates, usually micrite) that extends through the Swabian Alb and Franconian Alb in Southern Germany.
