Most igneous rocks have a relatively homogenous mix of minerals which are interlocked.
The majority of minerals associated with igneous rocks are silicates. It is the proportion of certain silicate minerals that affects the color of igneous rocks. Igneous rocks that are high in orthoclase feldspar, quartz, and muscovite mica will be lighter in color than igneous rocks that are higher in olivine, pyroxene, amphibole, and biotite mica.
A rock is an agglomeration of different minerals. Minerals are classified into categories based on their chemistry: oxides, sulphides, silicates, carbonates etc. Rocks are classified primarily by the process that formed them: igneous, sedimentary, or metamorphic.
Five basic types:GraniteDioriteGabbroPeriodotitePegmatiteIngenious rocks are made up of at least two minerals.
they are found in approximetily 90 %in the earth crust
feldspar
Igneous.
Igneous rocks are formed from minerals such as quartz, feldspar, pyroxene, and olivine. These minerals solidify from magma or lava as it cools and hardens, resulting in the formation of igneous rocks.
because racks are rocks and minerals are minerals
igneous rocks are composed of silicate minerals
Igneous Rocks
igneous rocks- rocks that are formed from melted minerals. ore-a rock that has a large amount of minerals.

Mafic igneous rocks typically contain minerals like olivine, pyroxene, and amphibole which are not commonly found in felsic igneous rocks. These minerals have higher concentrations of iron and magnesium and form at higher temperatures as compared to the minerals present in felsic rocks.
No it is not. Sedimentary rocks are made of minerals.
Both are composed of minerals. Some sedimentary rocks contain pieces of igneous rocks.
Not necessarily. Intrusive igneous rocks, especially pegmatites, can have large crystals.
Igneous rock is formed from melted minerals that have solidified and cooled. This process can occur either beneath the Earth's surface, forming intrusive igneous rocks, or on the surface, leading to extrusive igneous rocks.
