Definition for andesitic composition?
Andesitic composition refers to a type of igneous rock that is intermediate in composition between basalt and rhyolite. It typically contains minerals such as plagioclase feldspar, amphibole, and pyroxene. Andesitic rocks are commonly found in volcanic arcs and are associated with convergent plate boundaries.
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 does it mean to have andesitic composition?
Having an andesitic composition means that a rock or magma contains a combination of minerals such as plagioclase feldspar, amphibole, and biotite, and has an intermediate silica content compared to other types of volcanic rocks. Andesitic compositions are commonly associated with subduction zones and are characterized by their moderate viscosity and tendency to erupt explosively.
Is feldspar a rock or mineral?
Feldspar is the name of a group of rock-forming minerals which make up as much as 60% of the Earth's crust. Feldspars crystallize from magma in both intrusive and extrusive rocks, and they can also occur as compact minerals, as veins, and are also present in many types of
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.

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 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.
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.

How are moon rocks similar to and different rocks on earth?
Minerals that make up moon rocks are the same minerals that are found on Earth. Some moon rocks have minerals that combine to form kinds of rocks that are not found on Earth. BlueStar(:
What two continents are rocks and minerals found on?
Rocks and minerals are found on every continent, not just two - they are found underneath the ocean as well.

Where on earth are minerals found?
Minerals make up the rocks of earth, so minerals are found wherever there are rocks at the surface. Water too is a mineral so this includes the oceans.
What are minerals of effusive rocks and products of fumoral activities?
minerals of effusive rocks are minerals that are found as result of cooling of magma
Why can minerals be found in rocks but rocks cannot be found in minerals?
Because rocks are made up of minerals but minerals aren't made up of rocks. Rocks are made up of little bits of many minerals. An example is granite. You know how it has speckles in it? Those are a bunch of mineral grains mixed up to form the rock granite.
Are minerals found in rocks?
Yes... Definitely.
