Granitic rock is intrusive igneous rock, meaning that it has been formed from the slow cooling of magma underground and will have visible crystals. Granitic, in general, refers to a mineral composition that is felsic in nature, meaning it consists of 69% or more silicate minerals, like quartz, alkali feldspars, and micas.

Why are granitic igneous rocks lighter in color than basaltic rocks?

Granitic igneous rocks are lighter in color than basaltic rocks because they contain more quartz and feldspar minerals, which are typically light in color. Basaltic rocks, on the other hand, contain more dark-colored minerals like pyroxene and olivine, giving them a darker color.


Copper is found in what type of rock?

Copper is commonly found in igneous and sedimentary rocks, typically associated with areas of volcanic activity or hydrothermal deposits. It can also be found in some metamorphic rocks that have undergone mineral alterations.


What igneous rocks have a mineral composition between that of granitic and basaltic rocks?

Andesite and diorite are two common igneous rocks that have a mineral composition intermediate between granitic and basaltic rocks. Andesite is fine-grained and contains plagioclase feldspar and pyroxene minerals, while diorite is coarse-grained and composed of plagioclase feldspar, amphibole, and other minerals.


What name is applied to coarse grained felsic igneous rocks?

Granite is the name applied to coarse-grained felsic igneous rocks. These rocks are primarily composed of quartz, feldspar, and mica minerals, giving them a light color and coarse texture.


What are 3 types of rocks found in the lithosphere?

The three main types of rocks found in the lithosphere are igneous rocks, which form from cooled and solidified magma; sedimentary rocks, which result from the accumulation and compression of sediments; and metamorphic rocks, which are formed from the alteration of existing rocks due to high pressure and temperature.

Does granitic lava explode?

No Granites are usually intrusive rocks.


Why are granitic and andesitic rocks as plentiful as they are on Earth?

Granitic and andesitic rocks are plentiful on Earth because they are primarily formed by the cooling and solidification of magma beneath the Earth's crust. These rocks are commonly found in continental crust due to the process of subduction, where oceanic crust is forced beneath the continental crust, leading to the melting and formation of granitic and andesitic rocks.


What kind of rock makes up the continental drift?

Lithospheric rocks, (Basaltic and Granitic rocks)


Andesitic rocks have mineral compositions between those of basaltic rocks and?

granitic rocks. They are typically intermediate in silica content and often contain minerals such as feldspar, amphibole, and pyroxene. Andesitic rocks are associated with volcanic activity at convergent plate boundaries.


Why are granitic igneous rocks lighter in color than basaltic rocks?

Granitic igneous rocks are lighter in color than basaltic rocks because they contain more quartz and feldspar minerals, which are typically light in color. Basaltic rocks, on the other hand, contain more dark-colored minerals like pyroxene and olivine, giving them a darker color.

Copper is found in what type of rock?

At what depth does granitic magma form?

Granitic magma forms at relatively shallow depths, typically between 1 and 10 kilometers beneath the Earth's surface. This type of magma is formed through the partial melting of continental crust, which is composed mainly of granitic rocks.


What kind of rocks make up continental crust and oceanic crust?

Continental crust is mainly composed of granitic rocks such as granite and rhyolite, which are light in color and less dense. Oceanic crust is primarily composed of basaltic rocks, specifically basalt, which are dark in color and more dense than granitic rocks.
