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

Dolomite solubility was measured at temperatures from 50 to 253 °C in aqueous 0.1 mol/kg NaCl solutions using a hydrogen electrode concentration cell (HECC) following the protocol applied in previous studies on carbonate mineral stability measurements ( Bénézeth et al., 2007, Bénézeth et al., 2009, Bénézeth et al., 2011 ).

Dolomite, CaMg(CO 3) 2, is common enough to be considered a rock-forming mineral. It is formed underground by the alteration of calcite. Many deposits of limestone are altered to some extent into dolomite rock. The details are still a subject of research. Dolomite also occurs in some bodies of serpentinite, which are rich in magnesium.

This study is the first to apply dolomite to tissue culture. Callus growth increased with increasing dolomite concentration and decreased to 200 mg/L. This result is in accordance with the study of Chutichudet et al. on grand rapids lettuce. Hence, dolomite is widely applied in agricultural systems because of its content .

The typical apatite and dolomite single minerals flotation recovery are displayed in Figure 8. The natural floatability of apatite and dolomite particles was quite poor. When a certain concentration of NaOL was added, the floatation recoveries of them were both over 80%, but …

The film was removed, and ambient air was flushed into jars for 5 min before taking gas samples. The jars were then air-tight sealed for 60 min using three-way stop-cock lids that had a rubber septum for gas sampling. ... On the other hand, increasing soil pH increased the concentration of NO 3 −-N when dolomite was applied to acidic soil.

Dolemite is a 1975 American blaxploitation crime comedy film and is also the name of its principal character, played by Rudy Ray Moore, who co-wrote the film and its soundtrack.Moore, who started his career as a stand-up comedian in the late 1960s, heard a rhymed toast about an urban hero named Dolemite from a regular at the record store where he worked, and decided to adopt the persona as an ...

The mechanism of film formation is, however, not well elucidated, and most investigators use the protocol developed by Messersmith et al. (H. Lee, S.M. Dellatore, W.M. Miller, P.B. Messersmith, Science 318 (2007) 426.) using a dopamine solution at a constant concentration of 2 g L(-1) in the presence of Tris(hydroxymethyl aminomethane) at pH 8.5.

Dolemite Is My Name ist eine biografische Komödie von Craig Brewer für Netflix, die am 7.September 2019 beim Toronto International Film Festivals ihre Weltpremiere feierte und am 4. Oktober 2019 in die US-Kinos kam. Die Filmbiografie erzählt von der Comedy- und Rap-Legende Rudy Ray Moore, gespielt von Eddie Murphy

Florida is currently one of the largest phosphate producers in the world. Unfortunately, the phosphate industry in Florida is suffering from depletion of the phosphate-rich ore. Dolomite, however, is a major impurity in the ores. The presence of MgO, in dolomite, can cause several problems during production of phosphoric acid and final fertilizers. Efforts to solve the dolomite problem have ...

It can be concluded, therefore, that the heterogeneous (mainly epitaxial) nucleation of calcite on the dolomite surface creates a protective layer inhibiting the dissolution of dolomite. The efficiency of this barrier may depend critically on temperature and alkali concentration: for 0.1 molar solution of NaOH, only 22.5% of dolomite was ...

Dolomite was the first fertilizer used to prevent hypomagnesemia (Cunningham, 1936).When applied at rates between 100 and 540 kg Mg/ha the Mg concentration of temperate forage is increased by 0.2–1.2 g/kg DM (Table 9.13).These increases in Mg concentration in the forage were associated with a rise in the level of exchangeable Mg in the soil (Jones, 1963b; Simpson, 1964).

Thin section of dolomitic rock, (d) Dolostone DHF, (e) NJA. Dolostone DHF (fine-crystal dolomite) and NJA (putty- powder dolomite) contain 85–99% of dolomite and acid insoluble residues including quartz (1–2%) and illite. The sizes of dolomite DHF crystals are 40–100 μm in size and sometimes up to 400 μm. (f) Dolomitic limestone CK.

Dolomite is very similar to the mineral calcite.Calcite is composed of calcium carbonate (CaCO 3), while dolomite is a calcium magnesium carbonate (CaMg(CO 3) 2).These two minerals are one of the most common pairs to present a mineral identification challenge in the field or classroom.

The "Dolomite Problem" has been a controversy for over a century, owing to massive assemblages of low-temperature dolomite in ancient rocks …

Lime or dolomite is commonly implemented to ameliorate soil acidity. However, the impact of dolomite on CO2 emissions from acidic soils is largely unknown. A 53-day laboratory study was carried out to investigate CO2 emissions by applying dolomite to an acidic Acrisol (rice-rapeseed rotation [RR soil]) and a Ferralsol (rice-fallow/flooded rotation [RF soil]). Dolomite was dosed at 0, …

Dolomite is a very common mineral, and is known for its saddle-shaped curved crystal aggregates. A unique, isolated Dolomite occurrence in Eugui, Spain has provided colorless transparent crystals that resemble the Iceland Spar variety of Calcite.The occurrence of Kolwezi, in the Congo, has produced some fascinating, cobalt-rich specimens that are a beautiful hot pink color and highly popular.

We investigated the dissolution of a natural Fe-containing dolomite [Ca1.003Mg0.972Fe0.024Mn0.002(CO3)2] under acidic conditions (pH 3–5.5) with atomic force microscopy (AFM) at 20 °C and with batch dissolution experiments at 80 °C. Dolomite dissolution proceeded by two identified mechanisms: removal of dolomite layers through spreading and …

Dolomite rock (also known as dolomite, dolostone or dolomitic rock) is a sedimentary carbonate rock that contains a high percentage of the mineral dolomite, CaMg(CO 3) 2. In old USGS publications, it was referred to as magnesian limestone, a term now reserved for magnesium-deficient dolomites or magnesium-rich limestones.

Quantitative calculations with the geochemical program PHREEQC© for the replacement of calcite by dolomite in brine solutions were performed under the condition that total mineral rock volume is conserved. These simulations, using brine solutions derived from the evaporation of two "end member" compositions for Phanerozoic seawater, indicate that calcium (Ca2+) molalities in solution do ...

Two generations of carbonate cement as Type I (microcrystalline calcite and dolomite) and Type II (mainly Fe-calcite and Fe-dolomite) are recognized in Chang 8 sandstones, Ordos basin. Carbonate cement in Chang 8 sandstones is closely related to the dissolved carbon from thermal maturation of organic matters. Carbonate cement in the loosely packed framework grains precipitated shortly after ...

Dolomite, a calcium magnesium mineral (CaMg(CO3)2), is considered an undesirable accompanying mineral in the phosphoric acid production process and, as such, large quantities of this mineral are available in Florida. This study is aimed toward the characterization of the high-concentration phosphatic dolomite pebbles (handpicked dolomites) received from the Florida Industrial and Phosphate ...
