What is Dolomite? Dolomite, also known as "dolostone" and "dolomite rock," is a sedimentary rock composed primarily of the mineral dolomite, CaMg(CO 3) 2.Dolomite is found in sedimentary basins worldwide. It is thought to form by the postdepositional alteration of lime mud and limestone by magnesium-rich groundwater.. Dolomite and limestone are very similar rocks.

The uses and properties of the mineral Dolomite. What is Dolomite? Dolomite is a common rock-forming mineral.It is a calcium magnesium carbonate with a chemical composition of CaMg(CO 3) 2.It is the primary component of the sedimentary rock known as dolostone and the metamorphic rock known as dolomitic marble.Limestone that contains some dolomite is known as dolomitic limestone.
Dolomite (/ ˈ d ɒ l ə m aɪ t /) is an anhydrous carbonate mineral composed of calcium magnesium carbonate, ideally CaMg(CO 3) 2. The term is also used for a sedimentary carbonate rock composed mostly of the mineral dolomite.
Dolomite is used as an ornamental stone, a concrete aggregate, and a source of magnesium oxide, as well as in the Pidgeon process for the production of magnesium. It is an important petroleum reservoir rock, and serves as the host rock for large strata-bound Mississippi Valley-Type (MVT) ore deposits of base metals such as lead, zinc, and copper.
WHAT IS DOLOMITE? Dolomite differs from Limesand and Limestone in that it contains magnesium as well as calcium. It is used to supply both of these elements and is a very effective neutralizing agent.
VISUAL ANALYSIS OF LITHOLOGY / MINERALOGY: ... You must know whether the density neutron log is recorded on Sandstone, Limestone, or Dolomite porosity scales, before you apply Crain's Rule #6. The porosity scale on the log is a function of choices made at the time of logging and have nothing to do with the rocks being logged. Ideally, sand ...
Sandstone and limestone are common rocks found throughout the world. They create some of the dramatic landscapes you can find across the U.S. As sedimentary rocks, they share certain similarities. However, their different origins and compositions make them unique.

Dolomite Rock Trail is a 2.6 mile lightly trafficked loop trail located near Camdenton, Missouri that features a river and is rated as moderate. The trail is primarily used for hiking and trail running and is accessible year-round. Dogs are also able to use this trail but must be kept on leash.
Overview Information Dolomite is a type of limestone. It is rich in magnesium and calcium carbonate. It also has smaller amounts of several other minerals.
Dolomite is the leading supplier of crushed stone, sand and gravel, and recycle materials in the Greater Rochester Area and Southern Tier. Our products are used in a wide variety of construction applications as well as in the asphalt and concrete industries.
Dolomite porosity is lower than limestone porosity in the near surface, but does not decrease as rapidly with depth . The two porosity curves intersect at about 5,600 ft (1,700 m), below this depth dolomite is more porous than limestone.
The mineral content of Limestone includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt and mineral content of Sandstone includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all Sedimentary Rocks .
The dolomites have the lowest porosities (2–6%), the shales have the widest range of porosities (8–29%, although most are less than 15%), and the sandstones have the highest porosity (11–32%).

The types of Dolomite are Boninite and Jasperoid whereas types of Sandstone are Grey Sandstones, Crystallized Sandstones, Hard Sandstones, Carbonate Cemented Sandstones and Ganister. Streak of rock is the color of powder produced when it is dragged across an unweathered surface.
Dolomite: Perspectives on a Perplexing Mineral Dolomite is a metastable carbonate. It forms in a variety of distinctly different settings and can change as conditions change. The mode of formation influences dolomite morphology and thus impacts exploration …

Dolomite crystals also line or fill pores in carbonate limestone and dolostone rocks or in hydrothermal veins. Other important dolomite occurrences include marble rocks formed from the alteration of sedimentary dolostone, and dolomite associated with altered ultramafic igneous rocks like serpentinite.

Wisconsin's aquifers; A rock or soil formation that can store or transmit water efficiently is called an aquifer. Wisconsin's groundwater reserves are held in four principal aquifers: the sand and gravel aquifer, the eastern . dolomite aquifer, the sandstone and dolomite aquifer, and the crystalline bedrock aquifer..
