Basaltic igneous rocks are?
Light colored
Why are granitic igneous rocks light in color?
granitic igneous rocks are light colored because of a lower density than basaltic rocks
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.
Is peridot in igneous rock?
Yes, peridot is often found in igneous rocks, particularly in basaltic lavas and ultramafic rocks like peridotite. It can also be found in some metamorphic rocks that formed from the alteration of these igneous rocks.
What is igneous that have mineral composistions between those grantic and basaltic rocks?
andesitic rock
What color of igneous rocks does basaltic magma form?
Generally dark with shades of green and black.
When An igneous rock that contains mostly plugholes feldspar and about W percent dark silicates minerals has a composition that is?
Igneous rocks containing mostly plagioclase feldspar and a significant percentage of dark silicate minerals are typically classified as basaltic rocks. These rocks have a composition that is intermediate between mafic and felsic rocks, with a silica content of around 50-60%. Basaltic rocks often form from the solidification of magma with a basaltic composition.
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 is the difference between granitic igneous rocks and basaltic igneous rocks?
Basalt is an igneous rock with very fine grains. It is dark colored. Granite is a variety of colors: gray, pink, and white. It has coarse grains.
Definitions for basaltic composition?
a compositional group of igneous rocks indicating that the rock contains substantial dark silicate minerals and calsiumrich plagioclase feldspar. a compositional group of igneous rocks indicating that the rock contains substantial dark silicate minerals and calsiumrich plagioclase feldspar.
Basaltic magma would form what color of igneous rocks?
baslt
Light-colored igneous rocks with a lower density than basaltic rocks?
Felsic rocks like granite are light-colored igneous rocks with a lower density than basaltic rocks due to their silica-rich composition. Their lower density is a result of having a higher proportion of quartz and feldspar minerals, which are lighter than the minerals found in basalt.
