What determined the composition of a rock?
The composition of a rock is decided by the % of the constituent minerals and components contained inside it. The minerals that form up rocks have outlined chemical compositions and rigid atomic structures. once daylight strikes the rock's surface, the composition and atomic structure of the various minerals
What is the composition of silicates?
Silicate minerals make up 30% of all minerals, and they are minerals which contain both siliconm and oxygen.
The chemical makeup of a rock describes either the minerals or other materials in the rock?
Composition
What If two minerals have the same chemical composition but cleave into different shapes what is true?
They have different structures.
Why is a boulder not a mineral?
A mineral is a naturally occuring chemical compound. A mineral is different from a rock/boulder which can be an aggregate of minerals, or non minerals and does not have a specific chemical composition as a mineral does
Is syenite granitic?
Syenite is not granitic. Quartz is one of the main minerals found in granitic rock. Syenite contains little or no quartz, but otherwise has the same general composition as granite.
What are granitic rocks?
Granitic rock is intrusive igneous rock, meaning that it has been formed from the slow cooling of magma underground and will have visible crystals. Granitic, in general, refers to a mineral composition that is felsic in nature, meaning it consists of 69% or more silicate minerals, like quartz, alkali feldspars, and micas.
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 is the layer of rock under the surface of the earth is called?
The lithosphere is the hard, brittle outer layer of the Earth, comprised of the crust and uppermost mantle.
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 is the consistency of basaltic lava?
No, it is actually one of the less viscous.The viscosity increasing when the composition of Felsic minerals make larger.That is, basalt lavas are more fluent than felsic lavas such as lavas from andesite of rhyolite. Also, the more viscosity, the more explosive.
What are types of rocks and minerals found in the island of Hawaii?
Mostly basaltic lavas.
Minerals are classified according to their .?
Minerals are classified according to their composition
Basaltic magma forms what kind of igneous rock?
Mafic igneous rock. ( due to Ferromagnesian minerals).

What is the composition of geniss?
by altering bands of minerals
