Question

Select the option that lists oxide minerals only.

• A. Spinel, Corundum, Rutile
• B. Olivine, Pyroxene, Magnetite
• C. Apatite, Galena, Monazite
• D. Fluorite, Halite, Calcite

Hint:

When identifying oxide minerals, look for compounds where oxygen is bonded with metals, such as aluminum oxide, titanium oxide, or iron oxide.

Answer 1

The Correct Option is A

Step 1: Understanding Oxide Minerals
Oxide minerals are those in which oxygen is bonded with one or more metals. Common oxide minerals include spinel, corundum, and rutile, all of which have oxygen atoms combined with metal ions.

Step 2: Evaluating the Options
Spinel, Corundum, and Rutile are all oxide minerals. Spinel is composed of magnesium and aluminum oxide, corundum is aluminum oxide, and rutile is titanium dioxide.
Olivine and Pyroxene are silicate minerals, not oxides.
Apatite, Galena, and Monazite are phosphate and sulfide minerals, respectively, not oxides.
Fluorite, Halite, and Calcite are halide, salt, and carbonate minerals, respectively, not oxides.
