Sink

A sink, also known by other names including sinker, washbowl, hand basin, wash basin and simply basin, is a bowl-shaped plumbing fixture for washing hands, dishwashing, and other purposes.Sinks have a tap (faucet) that supply hot and cold water and may include a spray feature to be used for faster rinsing. They also include a drain to remove used water; this drain …

Sedimentary rock

Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a sedimentary rock are called sediment, and may be composed of geological detritus …

Caliche: Also known as calcrete, hardpan, and duricrust

"Caliche Terraces": Caliche-cemented gravels form the flat, resistant, horizontal "cap rocks" on the Pleistocene terraces on the banks of the modern dry wash that crosses the area shown in this photo. The mountains in the distance are composed mainly of Paleozoic limestones and dolomites. Weathering of these rocks provided much of the calcium carbonate that enabled …

calcite | mineral | Britannica

Between 60 and 70 elements have been recorded in minor or trace amounts in limestone analyses. Some of these elements may occur as substitutions within calcite; others seem more likely to represent minor constituents, such as clay minerals, within the analyzed rocks.. The chemical composition of calcite is responsible for the test that is widely used to identify it, …

Calcite

Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO 3).It is a very common mineral, particularly as a component of limestone.Calcite defines hardness 3 on the Mohs scale of mineral hardness, based on scratch hardness comparison.Large calcite crystals are used in optical equipment, and limestone composed mostly of calcite has …

Chert

Chert (/ ˈ tʃ ɜːr t /) is a hard, fine-grained sedimentary rock composed of microcrystalline or cryptocrystalline quartz, the mineral form of silicon dioxide (SiO 2). Chert is characteristically of biological origin, but may also occur inorganically as a chemical precipitate or a diagenetic replacement, as in petrified wood.. Chert is typically composed of the petrified remains of ...

Aggregates

Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and portland cement, are an essential ingredient in concrete.

Coquina: Limestone composed almost entirely of fossil debris

Coquinoid limestone is similar to coquina, but the spaces between the shell debris are occupied by fine-grained carbonate material. Mineral and Chemical Composition. Coquina and related sedimentary rocks are composed mainly of calcium carbonate. When the deposits are geologically young, much of the calcium carbonate is in the form of aragonite ...

Everything You Need to Identify Rocks

Igneous rocks such as granite or lava are tough, frozen melts with little texture or layering.Rocks like these contain mostly black, white and/or gray minerals. Sedimentary rocks such as limestone or shale are hardened sediment with sandy or clay-like layers (strata).They are usually brown to gray in color and may have fossils and water or wind marks.

Conglomerate: Sedimentary Rock

Clasts of quartzite, sandstone, limestone, granite, basalt, and gneiss are especially common. The matrix that binds the clasts together can be a mixture of sand, mud, and chemical cement. ... is composed of well-rounded clasts of quartz and sedimentary rocks of various sizes and kinds along with a fine-grained matrix. To work well as a ...

    How Limestone is Formed

    Chalk is a fine-grained, porous limestone while travertine is a freshwater, more sedimentary limestone that has thin layers. Marble is also a carbonate rock that has been squeezed down and formed into a different material with heat and …

    shale | rock | Britannica

    shale, any of a group of fine-grained, laminated sedimentary rocks consisting of silt- and clay-sized particles. Shale is the most abundant of the sedimentary rocks, accounting for roughly 70 percent of this rock type in the crust of the Earth. Shales are often found with layers of sandstone or limestone. They typically form in environments where muds, silts, and other sediments …

    Dolostone (Limestone)

    The principal mineral of limestone is calcite (CaCO3), a form of calcium carbonate. Dolostone is quite similar to limestone, but is composed mostly of the mineral dolomite (CaMg(CO3)2). Both are sedimentary rocks that occur as thin to massive beds of fine- to coarse-grained rock.
