  • 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.

  • What is black limestone made of, and how is it formed

    Black limestones are generally formed in depositional environments with restricted circulation and high organic content such as a lagoon. This results in reducing/anaerobic conditions limiting the presence of organisms that feed on/decay the organic matter, similar to a backswamp environments in clastic settings. 102 views

  • What Is the Difference Between Limestone & Calcite

    OverviewAppearanceUsesFormationApplicationsCalcite is a mineral that occurs in the natural geological processes of the Earth. Calcite is a form of calcium carbonate, a type of calcium salt oxide with three atoms of oxygen bonded to one atom of calcium. Calcite binds with other compounds to create limestone which is used in construction. When using these substances as building materials, the differences between calcite and limestone become clear.在hunker上查看更多信息

    The lowest unit comprises a mixture of calcite mudstones, white oolitic limestones and dark splintery limestones. This interval is relatively expanded in the Cheddar area, where a 38 m thick dark limestone ('Cheddar Limestone Member') is overlain by a 58 m thick white oolitic limestone ('Cheddar Oolite Member'). The middle part of the succession is dominated by fine-grained, grey-black

    01/08/2004· Mechanical e-twinning of calcite is the dominant crystal–plastic deformation mechanism in coarse-grained limestone and marble deformed at temperatures below about 400 °C (Turner, 1953, Carter and Raleigh, 1969, Groshong, 1988).Twins in calcite deformed at temperatures below 170 °C are typically thin, appearing only as thin black lines under the optical microscope ().

  • Nodule (geology) Wikipedia

    In sedimentology and geology, a nodule is a small, irregularly rounded knot, mass, or lump of a mineral or mineral aggregate that typically has a contrasting composition, such as a pyrite nodule in coal, a chert nodule in limestone, or a phosphorite nodule in marine shale, from the enclosing sediment or sedimentary rock.Normally, a nodule has a warty or knobby surface and exists as a discrete
