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.
What composition refers to rocks with many dark silicate minerals and plagioclase feldspar?
nig
What minerals are in granite but not gabbro?
Granite contains Quartz and Plagioclase Feldspar and Gabbro does not have neither if these minerals in it.
What is granodiorite?
Granodiorite is an intrusive igneous rock. Its composition is similar to that of granite but it contains more plagioclase than potassium feldspar. Biotite and hornblende are also abundant minerals in granodiorite.
What happens to plagioclase feldspar when it is weathered?
It forms clay minerals.

A certain igneous rock contains about 25 percent dark silicate minerals The remainder of the rock is mostly plagioclase feldspar What type of composition does tthis igneous rock have?
ultramafic
Igneous rock that contains many dark silicate minerals and that also are rich in magnesium and iron have composition that is?
Basaltic Composition are Igneous rocks composed mostly of dark silicate minerals and plagioclase feldspar. Rich in elements of magnesium and iron. It is also known as mafic.
What happens to plagioclase feldspar when it is weathered?
It forms clay minerals.
What is the chemical composition of a basalt?
The mineralogy of basalt is characterized by a preponderance of calcic plagioclase feldspar and pyroxene. Olivine can also be a significant constituent.
The two most abundant minerals always present in granite are?
Quartz, Plagioclase Feldspar, and Alkaline Feldspar.
Essential minerals of rock basalt?
anorthite-rich plagioclase, feldspar and augite
Rocks that contain dark silicate minerals and plagioclase feldspar have?
Intrusive crystal
What do all these minerals quartz plagioclase feldspar microcline feldspar hornblende and biotite have in common?
They are all found in Granite
