Rocks that contain dark silicate minerals and plagioclase feldspar have?
Intrusive crystal
What four minerals make up rocks in the intermediate family?
Plagioclase feldspar, hornblende, pyroxene, biotite mica
Which minerals do you think have a higher value iron containing minerals or feldspar?
Because feldspar minerals are much more plentiful, and iron minerals are vital to the manufacture of steel, iron containing minerals would logically have more value.
What three mineral are most commonly found in the igneous rock granite?
Rocks are composed of minerals. Three minerals found in granite are quartz, feldspar and mica. They are present in granite in differing amounts so all granite doesn't look the same.
What are the ten most rock- forming minerals?
Quartz, Potassium Feldspar, Plagioclase Feldspar, Muscovite (mica), Biotite (mica), Amphibole (hornblende), Pyroxene, Olivine, Calcite, Dolomite.
What composition refers to rocks with many dark silicate minerals and plagioclase feldspar?
nig
What type of composition does an igneous rock have that contains mostly plagioclase feldspar and about 30 percent dark silicate minerals?
Andesitic
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 happens to plagioclase feldspar when it is weathered?
It forms clay minerals.
The two most abundant minerals always present in granite are?
Quartz, Plagioclase Feldspar, and Alkaline Feldspar.
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.
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
What type of rock is a plagioclase?
Plagioclase is not actually a rock, but a member of the feldspar family of minerals, and a major rock forming silicate mineral.
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.
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.
