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.
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 are the three families of igneous rocks?
The three families of igneous rocks are basaltic (mafic), andesitic (intermediate), and granitic (felsic). These families are classified based on their silica content and mineral composition, which in turn influence their color, density, and overall characteristics.
Compared to the oceanic crust the continental crust is?
Thicker, less dense, and older than oceanic crust. It primarily consists of granitic rock, is less abundant, and makes up the continents' landmasses. Continental crust also tends to have higher elevations and is more likely to contain mineral resources.
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.
Which mineral is found most frequently in both granitic continental crust and basaltic continental crust?
Plagioclase Feldspar and Biotite and Amphibole

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.
What is the first mineral to crystalize out of a hot basaltic magma?
Olivine
What is igneous that have mineral composistions between those grantic and basaltic rocks?
andesitic rock

What is a mineral that effects the thickness of magama?
The more silica in lava, the more viscous the lava is. Silica (SiO2) content varies from 50 percent to 70 percent. Basaltic lava, which is 50 percent silica, is runny and contains relatively little gas. Granitic lava, typically around 70 percent silica, is 70 percent silica. It is much thicker and contains much more gas. As a result when granitic lava flows, it tends to release gasses (water and carbon dioxide) explosively. The lava on the Hawaiian Islands in basaltic, and flows easily. The lava in Mount St Helens is very thick, so when it finally reaches the surface it causes a much more violent and dangerous eruption.
Why is oceanic crust predominantly basalt while continental crust is mainly granitic in composition?
Basalt is very dense while granite is lighter and can "float" on the basaltic oceanic crust. The Continental plates shift with the oceanic plates as the heavier basalt sub-ducts under the lighter granite.
