dolomite, type of limestone, the carbonate fraction of which is dominated by the mineral dolomite, calcium magnesium carbonate [CaMg(CO 3) 2].. General considerations. Along with calcite and aragonite, dolomite …
1. Introduction. Acid stimulation in carbonate rocks represents a quintessential application of reactive flow in subsurface porous media [1, 2].During acid stimulation, the acid solution is introduced into low-permeability carbonate reservoirs or zones contaminated near the wellbore during the production or injection process, all …
Those that form from organic remains are called bioclastic rocks, and sedimentary rocks formed by the hardening of chemical precipitates are called chemical sedimentary rocks. Table 4.2 shows some common …

Dolomite is a trigonal–rhombohedral, ordered Ca, Mg carbonate mineral (CaMg (CO 3) 2) occurring primarily in sedimentary and metamorphic rocks. …
The related studies on the dolomite system are far more limited in number, and this work is motivated to improve the understanding of the acid stimulation process in dolomite carbonate rocks.
Dolomite is a type of sedimentary carbonate rock that consists mainly of dolomite mineral. Dolomite was originally known as Dolomieu; it was named after a French geologist, Deodat Guy Dolomieu. Dolomite can be referred to as dolomite mineral and dolomite rock. Dolostone is another name for dolomite rock. Dolomite comes …
The "dolomite problem", which has confused scientists for nearly two centuries, is an important fundamental geological problem. The mineralogical characteristics of carbonate minerals show that the dolomite structure consists of an ordered arrangement of alternating layers of Ca2+ and Mg2+ cations interspersed with CO32− anion layers …
To determine the dolomite distribution, the photoelectric factor in barns per electron (PEF) and GR logs for Tai1, XD1, and JP7 wells were collected to calculate the dolomite content through the whole T 1 f 3 strata using the method of the Rock Physics Model, assuming that the T 1 f 3 carbonates consist only of calcite and dolomite …

The key factors controlling formation of dolomite, including transition or recrystallization from precursor high-Mg calcite or proto-dolomite, at low temperatures …
Process 1: Crushing and screening dolomite rock. The crushing and screening process is to obtain dolomite blocks. Dolomite blocks can be directly used as sand and gravel products in the construction industry, and can also be ground or calcined to obtain other products.
In this paper, the Johnson-Holmquist II (JH-2) model with parameters for a dolomite rock was used for simulating rock fragmentation. The numerical simulations were followed by experimental tests.
Rocks are classified based on how they were formed. The three major types are igneous, sedimentary, and metamorphic rocks. ... Usually, these processes occur deep below Earth's surface. The …
The rock samples used in this study were mainly dolomite. The rock was relatively complete with developed cracks. Some rock samples had no complete structure and were scattered. ... put forward the calculation method of crack volume strain in the process of uniaxial compression of rock, and believed that the volume strain of rock …
Dolomite: A Mineral and a Rock "Dolomite" is a word that is used by geologists in two different ways: 1) as the name of the mineral dolomite; and, 2) as the name of a rock known as dolomite, dolostone, or dolomite rock. This page is about dolomite rock. If you are looking for an article about the mineral, please go here.
Lakirouhani et al. investigated the influence of the grain size of dolomitic rock samples on compressive strength in Iran, a country where Dolomite is one of the most important mineral ...
A wide range of geochemical methods may be used to characterize dolomites and dolostones, and to decipher their origin. The most widely used methods are the …
The Process Of Dolomitization Explained: What You Should Know. Dolomite mining includes various geological aspects for profitable mineral extraction. Dolomite crystals …
In the paper, the formation mechanisms of porosity in replacement dolostones ever proposed worldwide are summarized, and they can be divided into two main …
The wide distribution of dolomite rocks in North American, Middle- and Far-Eastern hydrocarbon reservoirs is reason enough for their intensive study. In this volume dolomite enthusiasts review progress and define the current boundaries of dolomite research, related particularly to the importance of these rocks as reservoirs.
An increase in the holding time of the acid composition in a rock containing practically one dolomite does not always lead to a more significant processing efficiency. Since there is clogging of the newly formed channel with reaction products, which reduces the permeability of the formation, which is confirmed by laboratory studies;
fuzzy analytic hierarchy process method (Fuzzy-AHP). At last, the proposed method ... Preliminary division of dolomite sandy degree. Sanding degree Rock mass characteristics Discriminating indicators
Sedimentary rock - Limestones, Dolomites, Carbonates: 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 CaCO3). Dolomites are mainly produced by the …
The Process Of Dolomitization Explained: What You Should Know ... Granular dolomite in rocks tends to be light to dark gray, tan, or white. Dolomite crystals range from transparent to translucent, but dolomite grains in rocks are nearly opaque. Most dolomite marbles are coarsely granular with individual grains ranging between 2 and 6 millimeters.
The purpose of this paper is to investigate the migration of alkali ions in reacted dolostone and the process of dedolomitization of dolomite. Three dolostones from China were used. The internal standard method of X-ray diffraction (XRD) was chosen to determine the degree of dedolomitization in reacted dolostones.
Mining techniques for dolomite are similar to those used for other sedimentary rocks. Open-pit mining is the most common method, where layers of earth are removed to reach the …
