The six classes of non-silicate minerals are oxides, sulfides, carbonates, sulfates, halides and phosphates. Non-silicate minerals are defined as substances within the Earth that do not contain silicon and are less complex than silicate minerals such as quartz and sand. Minerals are based on the type of anion, or negatively charged ion, within the substance.Continue Reading
Oxides contain oxygen as the anion. These minerals include corundum, hematite, magnetite, chromite and limenite. Corundum is one of the hardest substances known to humanity and is made of aluminum and oxygen. Gems of corundum include rubies and sapphires. Hematite and magnetite are iron ores.
Sulfides and sulfates both contain sulfur; the difference is that sulfates also contain oxygen bound to sulfur, whereas sulfides just contain sulfur atoms. Pyrite, galena, chalcopyrite and bornite contain sulfides. Sulfates include gypsum, anhydrite and barite.
Carbonate minerals consist of carbon and oxygen atoms as anions. Calcite, dolomite, malchite and azurite are common carbonates. Some of these minerals produce bubbles when hydrochloric acid touches them. Phosphates consist of phosphorous bound to oxygen atoms. Apatite and turquoise are two common phosphate minerals.
Halide minerals contain fluorine or chlorine. Halite, or salt, is one of the most common halide minerals in the Earth. Fluorite and sylvite also contain halide gases.Learn more about Geology
Georgius Agricola systematized the study of rocks, minerals and fossils, creating a standard classification and naming system that had not existed before. Perhaps more than any other individual, Agricola is credited with the scientific study of geology through his personal observation and scholarly research.Full Answer >
"ROCK ON! Geology Collection" and "Geology Jeopardy" are some games about rocks and minerals. "ROCK ON!" is a hands-on learning game, while "Geology Jeopardy" is a browser-based computer game for use in the classroom.Full Answer >
MedicineNet and WebMD explain that insufficient evidence exists to support the benefits of colloidal minerals. However, people who use colloidal mineral supplements use them to treat conditions including arthritis, diabetes, flushing poisonous heavy metals from the body, improving general well-being, raising low energy, addressing mineral deficiencies, reducing aches and pains, reducing blood cell clumping, reversing early cataracts and turning gray hair dark again.Full Answer >
Silicate minerals form when silicon and oxygen, the two most abundant elements on earth, combine. These elements combine in what is called tetrahedron, which consists of one silicon and four oxygen atoms.Full Answer >
