Limestone: The Calcium Carbonate Chemical Sedimentary Rock

2017-9-22 · Sedimentary limestone deposits can be extensive, covering hundreds of square miles, and can be relatively uniform in thickness and quality. Therefore, limestone quarries can be large and long lived, mining limestone layers that can be hundreds of feet thick over areas of several square miles. Many quarries produce multiple products, and crushed ...

Limestone: Rock Uses, Formation, Composition, Pictures

Limestone is a sedimentary rock composed primarily of calcite, a calcium carbonate mineral with a chemical composition of CaCO 3. It usually forms in clear, calm, warm, shallow marine waters. Limestone is usually a biological sedimentary rock, forming from the accumulation of shell, coral, algal, fecal, and other organic debris.

Carbonate minerals present in ancient limestones and dolomites occur in one of three textural forms: (1) discrete silt to sand to coarser carbonate grains, or allochems, such as oöids or skeletal fragments, (2) mud-size interstitial calcium carbonate matrix called microcrystalline calcite or micrite, and (3) interlocking, 0.02- to 0.1-millimetre-diameter crystals of clear interstitial calcium carbonate cement or …

Hand Specimen. Pale yellow-grey mudstone containing the fossil remains of a small arthropod with a segmented exoskeleton. The rock is banded and shows some surface discolouration due to weathering. Rock fizzes with acid, so contains carbonate. This is a soft, though well consolidated limestone (the surface has been scratched).

Limestone Facts

Limestone is a sedimentary rock that contains at least 50% calcium carbonate (CaCO3). Because sedimentary rocks are made of various types of sediments, the other 50% of a limestone rock could be virtually any other mineral. Limestone originates in wet areas which mean it could also be composed of shells and waste matter from organisms.

Sedimentary rock

Sedimentary rock - Sedimentary rock - Limestones and dolomites: Limestones and dolomites are collectively referred to as carbonates because they consist predominantly of the carbonate minerals calcite (CaCO3) and dolomite (CaMg[CO3]2).

How do you recognize limestone and marble? [USGS]

Limestone forms when shells, sand, and mud are deposited at the bottom of oceans and lakes and over time solidify into rock. Marble forms when sedimentary limestone is heated and squeezed by natural rock-forming processes so that the grains recrystallize.

Limestone Petrology & Sedimentary Rock Information

Limestone is a sedimentary rock, mainly composed of mineral calcite. The primary source of the calcite is usually marine organisms, which settle out of the water column and are deposited on the ocean floors as pelagic ooze (but see lysocline for information on calcite dissolution). Secondary calcite may also be deposited in super-saturated ...
