Dolomite is a sedimentary stone, which means it was formed on the surface of the earth, as opposed to granite, for example, which is formed in magma chambers under the earthʼs surface. It can be found in abundance all over the world (as is the case in the Dolomite Alps in Italy) in sedimentary basins —which are warm, shallow, marine areas ...
Most materials are inherently brittle in colder temperatures, and the limestone which has more elastic than brittle tendencies is more vulnerable to fracturing in freezing temperatures. Frost wedging is so successful in nature that the stone industry mimics it as a non-explosive technique to separate pieces of stone. ... Dolomite (limestone ...
The theory is that the dolomites are more brittle then the limestone, and tectonic events which deform (i.e., ductile behavior) the limestone will fracture the dolomite (i.e., brittle behavior), creating super-K intervals. I've tried a few of the available web sites for civil engineering, but haven't found any good answers yet.

Dolomite should read about 3.0 barns/electron, providing an easy way to distinguish limestone from dolomite even if gas is present.

The Middle Ordovician Platteville Formation in Kansas is restricted to the north-east of the State and consists of dolomite, limestone, sandstone, and green shale. The basal part is a persistent dolomite that can be correlated across the region. The Platteville unconformably overlies the St. Peter Sandstone.
of limestone country. The exposed dolomite bedrock showed several features potentially relevant in the context of containment of infiltrating and dispersing groundwater contaminants. More dolomitic rocks in the sequence behaved in a more brittle fashion, so tectonic stresses during the Paleozoic orogenies fractured dolostones more thoroughly.
Dolomite (also known as dolomite rock, dolostone or dolomitic rock) is a sedimentary carbonate rock that contains a high percentage of the mineral dolomite, CaMg(CO 3) 2.It occurs widely, often in association with limestone and evaporites, though it is less abundant than limestone and rare in Cenozoic rock beds (beds less than about 65 million years in age).
Limestone is an occurring type of sedimentary carbonate rock found on Earth's surface. It is formed when crystals of calcium carbonate precipitate out of water containing dissolved calcium. Limestone is composed of minerals such as calcite and aragonite. Limestone consists of 80 percent calcite and Dolomite with more than 50% calcium carbonate.
Limestone that contains some dolomite is known as dolomitic limestone. ... Dolomite China is very porous and brittle. This dinnerware is the most economical of all china dinnerware. ... Vitrified China is vitrified during the single firing process at about 1200 °C in the kiln and is more durable than dolomite.
Dolomite is a complex mineral. It is relatively a soft mineral which can be easily crushed to a soft powder. The mineral is an anhydrous carbonate mineral consisting of a double carbonate of calcium (Ca) and magnesium (Mg). It is chemically represented by CaMg (CO3)2 or CaCO3.MgCO3.
Dolomite (/ ˈ d ɒ l. ə ˌ m aɪ t, ˈ d oʊ. l ə-/) 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. An alternative name sometimes used for the dolomitic rock type is dolostone
THREE FORKS FORMATION--Yellow and greenish-gray shale and dolomitic siltstone. JEFFERSON FORMATION--Fetid brown dolomite and limestone. BEARTOOTH BUTTE FORMATION--Red sandstone, limy siltstone, and limestone. Occurs only in the Beartooth Mountains. BIGHORN DOLOMITE--Gray massive cliff-forming siliceous dolomite and locally dolomitic limestone.
Finally, limestone and dolomite differ greatly in their strength and ductility. Abundant experimental (Handin et al., 1963; Hugman and Friedman, 1979) and field data (Stearns, 1967) suggest that dolomite is generally stronger and more brittle than limestone at the same burial depth. The preferential development of fractures in dolomite beds ...
Dolomite only has a hardness of ~4 but is very brittle and sharp it often forms with many small white, grey, clear or pink crystals. Because dolomite is sharp and can be broken easily, it can be ...
Porosity in limestone and dolomite reservoirs is created by primary conditions of deposition, and later altered by the secondary forces of moving ground waters. Meteoric waters are probably the most important reason for the existence of limestone and dolomite reservoirs. Waters charged with carbonic or organic acids are capable of dissolving ...
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.

Breaking Down the Difference Between Dolomite and Marble. Created when limestone and lime mud interact with magnesium-rich groundwater, dolomite is a sedimentary rock known for its characteristic white and gray coloring. While often mistaken for marble or quartzite, this natural stone has distinct features which separate it from all others.
Dolomite is more brittle than the more plastic limestone. It often contains a matrix of sand and algae which forms thinner beds (flaggy) relative to limestone. Where strata are flat-lying, dolomite is often laterally associated and "seaward" of evaporates and sandy deflation flat facies (sabhka), which erode faster than dolomite.

Crystal Structure of Dolomite. Dolomite is an anhydrous carbonate mineral composed of nominally equal parts calcium and magnesium, with the formula CaMg(CO 3) 2.Its chemical formula can be more clearly written as CaCO 3.MgCO 3.Because of the presence of two various cations, which form regular layers inside dolomite structure, dolomite crystal symmetry is lower than calcite.
Tests have been done at temperatures of 25 to 500°C, confining pressure to 10 kb, and different strain rates (10 −4 to 10 −7 per second) on 1- by 2-cm solid cylinders and 1.2- by 2.5-cm hollow cylinders (0.7-mm wall) of homogeneous, statistically Isotropic Solenhofen limestone, Blair dolomite, and glass.
More than half of the carbonate buildups consist of secondary dolomites, whereas adjacent ones are only slightly dolomitized. Examples occur at seven different stratigraphic levels: Keg River, Pine Point, Slave Point, Swan Hills, Leduc, Nisku, …

Limestone has hardness 3, volume of 2600 ÷ 2800 kg / m3, compressive strength 1700 ÷ 2600kg / cm2, water absorption 0.2 ÷ 0.5%. Silica limestone is more intense, but brittle and hard. Dolomite limestone has better mechanical properties than regular limestone. Limestone contains much clay (greater than 3%), the water resistance is poor.
Dolomite vs Marble Durability. In terms of a countertop, Dolomite will be able to endure more wear-and-tear than most Marbles. Less likely to etch, scratch, or stain, Dolomite can be an excellent option for high-risk areas like your kitchen or bathroom, while still boasting that refined Marble look. A Marble countertop will be at a higher risk ...
