How would the color and density of rock composed mostly of non-ferro magnesium silicate minerals differ from one made up mostly of ferro-magnesium silicate?
non-ferro magnesium silicate dominated rock would be lighter in color and less dense than ferro-magnesium silicate dominated rock. NOTE: The color of olive-green belong to the ferro-magnesium silicate dominated rock group.
mantle is composed of these rocks?
ferro magnesium silicate rocks
What is the percentage of the earths crust made up of non silicate minerals?
Only 10% of the Earth's crust is composed of non-silicate minerals. Examples of non-silicate minerals are barringerite, nickel phosphide, taenite and suessite.
What is the composition that contain many dark silicate minerals and that also are rich in magnesium and iron?
biotite
Is talc a metal?
Talc is not classified as a metal. It is a very soft hydrous silicate mineral composed of magnesium, silica and water
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.

Why non silicate minerals have wider variety of crystalline structures than silicate minerasls do?
Non-silicate minerals contain oxygen and native elements. They have metallic and non-metallic lusters, and are very common.
mantle is composed of these rocks?
ferro magnesium silicate rocks
What are femic minerals?
Ferro-magnesian silicate minerals ie containing iron and magnesium
The two major types of minerals are what?
Two examples are quartz and mica. Minerals are also classified as metallic or non-metallic.
What do silicate minerals contain?
They all contain the silicon-oxygen tetrahedron.
It is generally true that igneous rocks are composed of what type of mineral?
igneous rocks are composed of silicate minerals
What is the percentage of the earths crust made up of non silicate minerals?
Only 10% of the Earth's crust is composed of non-silicate minerals. Examples of non-silicate minerals are barringerite, nickel phosphide, taenite and suessite.
What are the nonsilicate mineral?
Non-silicate minerals do not contain the SiO4 ion. Non-silicate minerals are classified as oxides, sulfides, sulfates, halides, or carbonates. Some elements are also classified as minerals. There's also a metallic and non-metallic mineral classification. See the link below for examples.
What is the composition that contain many dark silicate minerals and that also are rich in magnesium and iron?
biotite
Is chalcedony silicate or nonsilicate?
Chalcedony is a cryptocrystalline form of silica, composed of very fine intergrowths of quartz and moganite. These are both silicate minerals.
