The following questions are commonly asked about minerals.
What is the difference between a mineral and a rock? A mineral is a substance that is formed either through biological, geological, or chemical processes, though it sometimes includes all three. It has a uniform chemical composition, which means that one part of a mineral is the same as another part. In contrast, a rock does not have a uniform chemical composition. One piece of a rock can be very different from another. In fact, rocks are formed by minerals aggregating together, again due to geological or chemical processes.
Is salt a mineral? Yes. Salt is a naturally occurring mineral that is found in the halide class of minerals. These include the halite, fluorite, sylvite, and sal ammoniac minerals. Halide minerals are formed through evaporation, where water leaves behind a thick halide layer. The Dead Sea and the Great Salt Lake are two examples of landlocked lakes that produce large natural salt deposits.
Where do phosphate minerals come from? Phosphate is a mineral group made out of phosphorus, antimony, arsenic, or vanadium. The most common source of phosphate minerals on our planet comes from apatite, which is found in the teeth and bones of animals. Because bones do not decay, the apatite from them is slowly transformed into a phosphate mineral.
What is the largest mineral group? Silicate minerals are by far the largest of minerals. This includes the beautiful quartzes, micas, and feldspars. They are formed through a chemical reaction that leaves the minerals consisting mainly of silicon and oxygen. Since most rocks are over 95 percent silica, it is no wonder that silicate minerals are the most common.
Minerals, natural substances, are elements such as gold and silver. Minerals can range in composition from pure elements to complex silicates, and the study of such substances is called mineralogy. In comparison, rocks are hard, naturally-formed masses of minerals or petrified matter. Rock shops sell various types of rocks and minerals to people who enjoy collecting them. Such elements can include hemimorphite, adamite, fluorite, calcite, apophyllite, scheelite, barite, galena, malachite, quartz, cerussite, tourmaline, amazonite, beryl and barite. Minerals and vitamins are nutrients the human body needs in order to thrive. Often, we don't get enough vitamins and minerals in our diet, and we need to take supplements to make sure we get a sufficient amount. Stores and dealers that sell minerals may also sell rocks, metal, gems, clay, crystals, trace elements, organic compounds, and colloidal minerals. If you are looking for vitamin and mineral supplements, visit a health foods store, nutrition store, or the health and beauty section of your local drug store. Consult with staff to find out about the best supplements to take if you're on a diet or are strength training. If you are looking for a specialist, collector, or dealer to buy from or sell to, search for dealers or shops in your area. Go online to do your research on how minerals affect water supplies, where you can find mineral foundation and makeup, which states are mineral rich, and where you can find a mineralogy tech expert in your area. The library is also a great resource to find out more on gems, vitamins, metals, crystals, industrial mining, natural elements, import laws, lists, pictures, photos, and more.
