Dolomite Rock Sedimentary Rocks Sandatlas

Dolomite or dolostone is a carbonate sedimentary rock containing more than 50% by weight of the mineral dolomite.Dolomite rock may contain calcite, but the content of calcite should not exceed 10% of the calcite-dolomite pair’s content 3.. Dolomite in Northern Norway (Trollholmsund) which was once chalk, but the original material has been replaced with dolomite.

Dolomitic sedimentary rocks

Interpreting Dolomite In Sedimentary Rocks. The Problem of Dolomite Limestone and dolomite are often found together, or closely associated, but their relationships are not always clear. " Pure" dolomite resembles micrite, being a fine-grained carbonate rock with conchoidal fracture, although it can be slightly granular too. But dolomite is a

Dolomite (mineral) Wikipedia

Dolomite is an anhydrous carbonate mineral composed of calcium magnesium carbonate, ideally CaMg(CO3)2. The term is also used for a sedimentary carbonate rock composed mostly of the mineral dolomite. An alternative name sometimes used for the dolomitic rock type is dolostone.

Sedimentary rock Limestones and dolomites Britannica

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). Almost all dolomites are believed to be produced by recrystallization of preexisting limestones, although the exact details of this dolomitization process

Sedimentary rock Carbonate rocks: limestones and

Carbonate rocks: limestones and dolomites. Limestones and dolostones (dolomites) make up the bulk of the nonterrigenous sedimentary rocks. Limestones are for the most part primary carbonate rocks. They consist of 50 percent or more calcite and aragonite (both CaCO 3).Dolomites are mainly produced by the secondary alteration or replacement of limestones; i.e., the mineral dolomite [CaMg(CO 3) 2

Rock Types Dolomite

Mineralogy: Contains a high proportion of dolomite (the mineral and the rock have the same name). Detrital minerals and secondary silica (chert) may be present. Field relations: Dolomites are usually interbedded with other limestone s and are commonly associated salt and gypsium deposits.

All You Need to Know About Dolomite for Kitchen Countertops

Mar 20, 2019· Dolomite rocks can be found in warm, shallow, sedimentary environments where large deposits of calcium carbonate mud tend to accumulate. When limestone and lime mud go through post-depositional chemical change and are modified as a result of it, dolomite is formed. Through a process known as dolomitization, the magnesium available in the

Missouri Department of Natural Resources

The geological definition of limestone is a sedimentary rock consisting of at least 50 percent calcite and dolomite, with less than 50 percent other rock materials. The practical, commercial definition of limestone is a sedimentary rock consisting of 80 percent calcite and dolomite, with less than 20 percent other rock materials.

Porosity and Bulk Density of Sedimentary Rocks

POROSITY AND BULK DENSITY OF SEDIMENTARY ROCKS By G. EDWARD MANGER ABSTRACT More than 900 items of porosity and bulk density data for sedimentary rocks have been tabulated. Most of the data are from the more accessible American, British, German, and Swiss literature. The number of porosity determinations per item ranges from 1 to 2,109.

The term dolostone, proposed to specifically refer to the rock type composed of the mineral dolomite, has not gained wide usage, and sedimentary petrologists continue to habitually use the term dolomite for both the rock and the mineral. Almost all dolomite is produced by converting CaCO 3 minerals into the mineral dolomite after the initial

University of Minnesota’s Mineral Pages: Dolomite

Dolomite forms in hydrothermal veins or as a pore-filling mineral in carbonate rocks, and more rarely as an accessory component in igneous pegmatites or altered mafic igneous rocks. By far though, most dolomite occurs in altered sedimentary marine rocks called dolostones or in marbles formed from the metamorphism of dolostone.

Dolomite Ohio History Central

Dolomite was named for the French mineralogist Deodat de Dolomieu. It is common in a sedimentary rock called dolostone. Dolostone is known also as dolomite, or sometimes as dolomitic limestone. Dolomite differs from calcite, the main component of limestone, because it contains the element magnesium (Mg) as well as calcium (Ca).
