What else can I help you with?
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
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.

Can calcite scratch other minerals if so which one?
No.because calcite is softer then feldspar
What element is common to all four of these minerals Quartz pyroxene olivine calcite?
All four minerals—quartz, pyroxene, olivine, and calcite—contain silicon as a common element. Quartz and olivine are silicate minerals, meaning they are composed primarily of silicon and oxygen, while pyroxene is also a silicate that includes other metal elements. Calcite, although a carbonate mineral, contains carbon and oxygen in addition to calcium but does not contain silicon. Thus, silicon is specifically common to the silicate minerals among them.
