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 else can I help you with?
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.
Is Andesitic rock is an igneous rock with a composition in between that of basaltic and granitic igneous rock.?
Yes, andesitic rock is an igneous rock that has a composition intermediate between basaltic and granitic rocks. It typically contains a mix of minerals such as plagioclase feldspar, amphibole, and sometimes biotite or quartz. Andesitic rocks are commonly associated with volcanic arcs and are often found in subduction zone environments. Their formation occurs from the partial melting of the Earth's mantle and the mixing of different magma types.
Is it true Andesitic rock is an igneous rock with a composition in between that of basaltic and granitic igneous rock.?
Yes, andesitic rock is indeed an igneous rock that has a composition situated between basaltic and granitic rocks. It typically contains a moderate amount of silica, ranging from about 57% to 63%, which gives it characteristics that are intermediate between the two. Andesitic rocks are commonly found in volcanic arcs and are often associated with subduction zones.
Why are andesitic and granitic rocks confined to the continents and ocean margins but absent from deep ocean basins?
The igneous rock underlying the deep ocean basins is basaltic, as its source material comes from the asthenosphere. Andesitic igneous rock is formed at colliding plate margins, where subducting oceanic crust is partially melted and undergoes differentiation as it rises through the continental crust. Granitic rock is less dense than oceanic crust and composes the continents.
Is granite rock a basaltic granitic andesitic or volcanic?
Granite is classified as a granitic rock, which means it is an intrusive igneous rock primarily composed of quartz, feldspar, and mica. Unlike basalt, which is a volcanic rock formed from the rapid cooling of lava, granite forms from the slow crystallization of magma beneath the Earth's surface. It is not andesitic or basaltic; those terms refer to different compositions and types of volcanic rocks.

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.

Granitic rock is less dense than oceanic crust and composes the continents.
Is limestone made up of fragments of granitic and andesitic rocks?
No. Limestone is formed from precipitated calcite or from the shells or skeletal remains of marine organisms.
Is granite rock a basaltic granitic andesitic or volcanic?
Granite is classified as a granitic rock, which means it is an intrusive igneous rock primarily composed of quartz, feldspar, and mica. Unlike basalt, which is a volcanic rock formed from the rapid cooling of lava, granite forms from the slow crystallization of magma beneath the Earth's surface. It is not andesitic or basaltic; those terms refer to different compositions and types of volcanic rocks.
What is the difference of andesitic and andesite?
Andesite is a type of extrusive igneous rock with moderate levels of silica. Andesitic is an adjective used to describe volcanic material with the composition of andesite. For example, andesitic lava will cool to form andesite.
What are the magmas the three families of igneous rock form from?
There are many different types of ignoues rock, but as a general description, mafic, felsic and intermediate rocks are formd from basaltic, granitic, and andesitic magmas respectively.
What are the three kinds of the earth igeans?
The three kinds of Earth Igneous Rocks are: basaltic (mafic), granitic (felsic), and intermediate (andesitic). These rock types vary in their mineral composition, color, density, and overall characteristics based on the amount of silica and other elements present. Each type forms from different magma compositions and processes within the Earth's crust.
Why are granitic igneous rocks light in color?
granitic igneous rocks are light colored because of a lower density than basaltic rocks
What are granitic rocks?
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.
