What minerals are found in mafic rocks?
mafic rocks can be made up of orthoclase feldspar and quartz
Name each member of the silicate family?
Quartz, feldspar, mica, and pyroxene are common members of the silicate mineral family.
What is plagioclase feldspar with quartz and olivine?
Plagioclase feldspar is a common mineral in igneous rocks, while quartz is a mineral often found in a variety of rocks. Olivine is a green mineral commonly found in mafic igneous rocks. When all three minerals are present in a rock, it typically indicates a mafic igneous rock such as basalt or gabbro.
What is the mafic mineral and felsic mineral?
First of all there is no such thing as a mafic or a felsic "mineral". There can be mafic and felsic rocks.Mafic rocks have a high magnesium and iron content.Felsic rocks enriched with lighter elements such as oxygen and silicon.
What minerals are present in felsic rocks and mafic rocks?
Felsic rocks are primarily composed of minerals like quartz, feldspar, and muscovite, while mafic rocks contain minerals such as olivine, pyroxene, and plagioclase. Felsic rocks have lighter-colored minerals and lower density compared to mafic rocks, which have darker-colored minerals and higher density.
Is quartz monzonite mafic or felsic?
Quartz monzonite ranges from intermediate to felsic.
What 3 elements do mafic rocks contain?
silicate oxygen and quartz
What is alaskite?
A plutonic rock consisting of oligioclase, microcline and quartz with subordinate muscovite and little or no mafic minerals. An alkali granite with no mafic minerals
Is diorate a metamorphic rock?
No, diorite is a simply an igneous rock with lots of mafic minerals and quartz.
An acid igneous rock A always contains quartz B never contains quartz C would be mafic D b and c above?
The best anwser would be A, that they contain quartz.

When all three minerals are present in a rock, it typically indicates a mafic igneous rock such as basalt or gabbro.
What mineral composition is most characteristic of felsic rocks?
Felsic rocks are typically composed of minerals such as quartz, potassium feldspar, plagioclase feldspar, and muscovite mica. These minerals are light in color and have lower densities compared to mafic rocks.
Why are mafic rocks denser than felsic rocks?
Mafic rocks have higher concentrations of dense minerals like iron and magnesium compared to felsic rocks, which are rich in lighter minerals like quartz and feldspar. This difference in mineral composition contributes to the higher density of mafic rocks.

Is Slate felsic or mafic?
Slate is classified as a metamorphic rock, and it does not fall into the categories of felsic or mafic, which are terms primarily used for igneous rocks based on their silica content. However, slate is typically derived from shale, which can be made up of both felsic and mafic minerals. The mineral composition of slate can vary, but it generally contains more quartz and clay minerals, leaning toward a felsic composition.
