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, because in order to be a silicate a mineral needs to have both silicon and oxygen. The composition for calcite is CaCO3. Calcite is a carbonate mineral.
Is limestone a silicate mineral?
No. Dolomite is formed by the replacement of Calcium in the mineral calcite by Magnesium, giving the chemical formula (Ca,Mg)CaCO3. Rocks formed largely of calcite are called limestones, and those which show extensive Magnesium substitution in calcite are called Dolomitic limestones.
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
Which list the minerals in the correct order from softest to hardest out of talcdiamondcalcitefeldspar?
The correct order of the minerals from softest to hardest is talc, calcite, feldspar, and diamond. Talc is the softest mineral, rated 1 on the Mohs scale, while diamond is the hardest, rated 10. Calcite and feldspar fall in between, with calcite rated at 3 and feldspar at 6.
List the following minerals in order of decreasing hardness apatite calcite corundum feldspar and talc?
In order of decreasing hardness, the minerals are corundum, feldspar, apatite, calcite, and talc. Corundum is the hardest among them, followed by feldspar, then apatite, with calcite being softer, and talc as the softest. This order reflects their positions on the Mohs hardness scale.
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 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.
What minerals scratch calcite?
Any mineral with a Mohs hardness of 3 or above. Diamond, for instance.
