What mineral composition is most characteristic of mafic rocks?
olivine, pyroxene, and calcium-rich plagioclase
What is the ore of mica?
The mineral mica occurs in large deposits in many metamorphic rocks.
What is the silicate mineral that is found in the greatest variety of igneous rocks?
Quartz is one of the most abundant silicate minerals found in igneous rock.
What mineral composition is most characteristic of felsic rocks?
felsic is orthoclase, quartz, and biotite. mafic is olivine, pyroxene, and calcium rich plagioclase. I am still researching intermediate.
What is the composition of rocks?
Rocks vary in composition depending the availability and type of mineral present during their formation.
What mineral composition is most characteristic of mafic rocks?
olivine, pyroxene, and calcium-rich plagioclase
Is limestone a silicate mineral?
No. Dolomite is formed by the replacement of Calcium in the mineral calcite by Magnesium, giving the chemical formula (Ca,Mg)CaCO3. Rocks formed largely of calcite are called limestones, and those which show extensive Magnesium substitution in calcite are called Dolomitic limestones.
What is the mineral classification of quartz?
The group of rocks that usually have the mineral quartz as part of their composition is the granitic group. Quartz is one of the last minerals to crystallize filling in the gaps in granite as it cools.
Is pyroxene a mineral?
A pyroxene is any of a group of crystalline silicate mineral common in igneous and metamorphic rocks.
It is generally true that igneous rocks are composed of what type of mineral?
igneous rocks are composed of silicate minerals
What is mineral rocks made of?
Rocks can contain almost any of the over 4,000 valid mineral species. Silicate minerals are contained in a large percentage of crustal rocks.
Coloured silicate mineral found in coarse granites and igneous rocks?
beryl
What are mineral composition of rocks?
Mostly death
What is the ore of mica?
The mineral mica occurs in large deposits in many metamorphic rocks.
What mineral group is talc in?
The word 'potash' refers to potassium compounds and materials which are potassium bearing. A mineral is defined as a naturally occurring inorganic crystalline solid with a definite chemical composition; therefore, potash is not a mineral as such, and is not a member of a mineral group.
What composition refers to rocks with many dark silicate minerals and plagioclase feldspar?
nig
What is the silicate mineral that is found in the greatest variety of igneous rocks?
Quartz is one of the most abundant silicate minerals found in igneous rock.
