What rock group is dolomite?
What rock group is dolomite?
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(CO3)2.
Is dolomite a metamorphic rock?
What is Dolomite? Dolomite is a common rock-forming mineral. It is a calcium magnesium carbonate with a chemical composition of CaMg(CO3)2. It is the primary component of the sedimentary rock known as dolostone and the metamorphic rock known as dolomitic marble.
Is dolomite a feldspar?
Dolomite is used to describe both a mineral and a rock. The mineral is the pure form with a defined crystal structure and chemical formula, whereas dolomite rock is composed chiefly of the mineral Dolomite, but also contains impurities such as Calcite, Quartz, and feldspar.
Where is dolomite mineral found?
Although rock beds containing dolomite are found throughout the world, the most notable quarries are located in the Midwestern United States; Ontario, Canada; Switzerland; Pamplona, Spain; and Mexico.
Is dolomite a limestone?
dolomite, type of limestone, the carbonate fraction of which is dominated by the mineral dolomite, calcium magnesium carbonate [CaMg(CO3)2].
Which ore is dolomite?
magnesium ore
2.1 Dolomite. Dolomite is a magnesium ore with the general formula MgCO3·CaCO3.
What is the ore of dolomite?
the correct answer is magnesium. Dolomite is a magnesium ore with the general formula MgCO3·CaCO3.
Where do dolomites come from?
The Dolomite Alps of northern Italy are a well-known example. Other relatively common occurrences of the mineral dolomite are in dolomite marble and dolomite-rich veins. It also occurs in the rare igneous rock known as dolomite carbonatite.
What is the mineral dolomite used for?
Dolomite is used as a source of magnesia (MgO), a feed additive for livestock, a sintering agent and flux in metal processing, and as an ingredient in the production of glass, bricks, and ceramics. Dolomite serves as the host rock for many lead, zinc, and copper deposits.
Is dolomite a chemical sedimentary rock?
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….

What type of minerals are calcite and dolomite quizlet?
The two most common carbonate minerals are calcite, CaCO3 (Calcium carbonate), and dolomite, CaMg (CO3)2 (calcium/magnesium carbonate).
What is chemical name of dolomite?
Dolomite is a magnesium ore with the general formula MgCO3·CaCO3.
Where is dolomite came from?
Dolomite originates in the same sedimentary environments as limestone – warm, shallow, marine environments where calcium carbonate mud accumulates in the form of shell debris, fecal material, coral fragments, and carbonate precipitates.
Can you eat dolomite?
Dolomite is POSSIBLY UNSAFE for most adults when taken by mouth. Some dolomite products might be contaminated with heavy metals like aluminum, arsenic, lead, mercury, and nickel. Because of this concern, it might be wise to choose a safer calcium or magnesium supplement.
What mineral group is calcite dolomite and rhodochrosite?
Carbonates
Carbonates are minerals composed of one or more metallic elements with the carbonate compound CO3. Examples of carbonates are calcite, dolomite, and rhodochrosite. Carbonates are the primary minerals found in rocks such as limestone, conquina, and marble.
Are calcite and dolomite both carbonate minerals?
Calcite and dolomite are both carbonate minerals. Nonmetallic minerals like quartz and gypsum have no industrial uses. Mineral luster is broadly classified as either being metallic or opaque. Ferromagnesian silicate minerals contain some magnesium and iron.
Is dolomite a sedimentary rock?
The principal mineral of limestone is calcite (CaCO3), a form of calcium carbonate. Dolostone is quite similar to limestone, but is composed mostly of the mineral dolomite (CaMg(CO3)2). Both are sedimentary rocks that occur as thin to massive beds of fine- to coarse-grained rock.
