Why are granitic igneous rocks light in color?
granitic igneous rocks are light colored because of a lower density than basaltic rocks
What is the difference between basaltic and frantic igneous rock?
There sedimentary igneous and metemorphic
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.
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 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 is same between basaltic and andesitic rock?
Both are classified as igneous rock.
What are rocks that form Earth's crust?
The rocks of the crust are igneous, sedimentary, and metamorphic in origin. The base rock of the oceanic crust are mainly basaltic and the base rock of the continental crust is mainly granitic.
Which mineral is most frequently found in both granitic continental crust and basaltic oceanic crust?
The mineral most frequently found in both granitic continental crust and basaltic oceanic crust is feldspar. Feldspar is a common mineral found in igneous rocks and is a major component of both types of crust due to its abundance and widespread distribution.
What is igneous that have mineral composistions between those grantic and basaltic rocks?
andesitic rock
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.
Is Pumis granitic?
no. pumice is a volcanic rock (igneous)
