Name the major groups of minerals and give at least two examples of minerals in each group?
The major groups of minerals are silicates (e.g., quartz and feldspar), carbonates (e.g., calcite and dolomite), sulfides (e.g., pyrite and galena), oxides (e.g., hematite and magnetite), and sulfates (e.g., gypsum and barite).
What are some examples of silicate and nonsilicate minerals?
Important examples of silicate mineral species include forsterite (in the olivine group), almandine (in the garnet group), epidote, schorl (in the tourmaline group), enstatite (in the pyroxene group), actinolite (in the amphibole group), muscovite (in the mica group), albite (in the feldspar group), stilbite (in the zeolite group), and quartz. Important examples of non-silicate mineral species include calcite, gypsum, fluorite, hematite, galena, and gold.
Is calcite a silicate?
No, calcite is not a silicate. Calcite is a carbonate mineral composed of calcium carbonate (CaCO3), while silicates are minerals that contain silicon and oxygen atoms in their chemical structure.
Is limestone a silicate mineral?
No, limestone is not a silicate mineral. Limestone is primarily composed of the mineral calcite, which is a carbonate mineral. Silicate minerals are those composed primarily of silicon and oxygen, such as quartz or feldspar.
Give at least two examples of minerals in each group?
Sure, here are two examples of common minerals in each group: Silicates: Quartz, Feldspar Carbonates: Calcite, Dolomite Sulfates: Gypsum, Barite Halides: Halite, Fluorite Oxides: Hematite, Magnetite Sulfides: Pyrite, Galena Native Elements: Gold, Diamond
Do a non silicate minerals contain oxygen?
Yes, non-silicate minerals can still contain oxygen. For example, carbonates such as calcite and dolomite are non-silicate minerals that contain oxygen along with carbon and other elements.
Are Oxygen in any minerals?
Yes oxygen is in Minerals such as Quartz Feldspar Beryl Hermatite Mica Calcite and others
What minerals scratch calcite?
Any mineral with a Mohs hardness of 3 or above. Diamond, for instance.
What is a non silicate mineral?
A non-silicate mineral is a mineral that does not contain silicon and oxygen as its primary components. Examples of non-silicate minerals include calcite (calcium carbonate) and halite (sodium chloride). These minerals have diverse chemical compositions and properties compared to silicate minerals.
10 most common rock forming minerals?
The 10 most common rock-forming minerals are quartz, feldspar (including orthoclase, plagioclase, and microcline), mica (including muscovite and biotite), amphibole (including hornblende), pyroxene (including augite and enstatite), olivine, calcite, clay minerals, garnet, and hematite.
Can calcite scratch other minerals if so which one?
Yes, calcite can scratch other minerals with a Mohs hardness of 1 to 2, such as gypsum and talc. However, it cannot scratch harder minerals such as quartz or feldspar.
What do quartz pyroxene olivine calcite have in common?
Both minerals have a vitreous luster, a white streak, and contain oxygen.
