Science & Origin of DolomiteDolomite is a calcium, magnesium, carbonate mineral that commonly forms in small clusters of rhomehedrical shaped crystals with saddle-shaped formations. This mineral can also be found in masses or grains and appears as white, grey, brown, green, pink and black.

Dolomite: A sedimentary rock known as dolostone or

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.

Marble Characteristics. Marble is a rock widely used in buildings, monuments, and sculptures. It consists chiefly of calcite or dolomite, or a combination of these carbonate minerals. Marble is a type of metamorphic rock formed from limestone. Marble is found in many countries, including Belgium, France, Great Britain, Greece, India, Italy, and

Limestone Characteristics PerfectGranite

Because of impurities, such as clay, sand, organic remains, iron oxide and other materials, many limestones exhibit different colours, especially on weathered surfaces. Limestone may be crystalline, clastic, granular, or dense, depending on the method of formation. Crystals of calcite, quartz, dolomite or barite may line small cavities in the rock.

The dolomite crystals precipitated as cements lining dissolution vugs and mouldic pores in Rd3 dolomites. 2) Cd2 dolomite cement (Fig. 3e, f), the Cd2, saddle dolomite cements are ranging from

Petrographic and geochemical characteristics of dolomite

Three major types of dolomite occur in the Trenton Formation (Mid-Ordovician) of the Michigan Basin. These are: (1) ‘regional dolomite’ which is confined to the extreme western edge of the basin; (2) ‘cap dolomite’ which occurs in the upper portion of the Trenton and is confined to the basin's southern margin; and (3) ‘fracture-related’ dolomite which occurs in association with

Genesis and characterization of dolomite, Arab-D

It has long been recognized that the Arab-D reservoir in Ghawar field contains a significant amount of dolomite rock (defined in this study as carbonate rocks that are composed of more than 75% of the mineral dolomite (Powers, 1962), and that the occurrence of dolomite is highly variable.Arab-D dolomites typically have pore systems and reservoir characteristics that are

The geochemical characteristics and formation mechanism

Among the carbonate rocks in the reservoirs, dolomite proves to be the high quality reservoir rock type. By the comprehensive petrologic, textural and geochemical studies, we describe and demonstrate the origin and characteristics of the two sorts of lacustrine dolomites from western Qaidam Basin. One is the protistic algal dolomite, which is
