1. minerals

   In geology and mineralogy, a mineral or mineral species is, broadly speaking, a solid chemical compound with a fairly well-defined chemical composition and a specific crystal structure that occurs naturally in pure form.The geological definition of mineral normally excludes compounds that occur only in living organisms. However, some minerals are often biogenic (such as calcite) or are organic compounds in the sense of chemistry (such as mellite). Moreover, living organisms often synthesize inorganic minerals (such as hydroxylapatite) that also occur in rocks. The concept of mineral is distinct from rock, which is any bulk solid geologic material that is relatively homogeneous at a large enough scale. A rock may consist of one type of mineral, or may be an aggregate of two or more different types of minerals, spacially segregated into distinct phases.Some natural solid substances without a definite crystalline structure, such as opal or obsidian, are more properly called mineraloids. If a chemical compound occurs naturally with different crystal structures, each structure is considered a different mineral species. Thus, for example, quartz and stishovite are two different minerals consisting of the same compound, silicon dioxide. The International Mineralogical Association (IMA) is the generally recognized standard body for the definition and nomenclature of mineral species. As of November 2022, the IMA recognizes 5,863 official mineral species.The chemical composition of a named mineral species may vary somewhat by the inclusion of small amounts of impurities. Specific varieties of a species sometimes have conventional or official names of their own. For example, amethyst is a purple variety of the mineral species quartz. Some mineral species can have variable proportions of two or more chemical elements that occupy equivalent positions in the mineral's structure; for example, the formula of mackinawite is given as (Fe,Ni)9S8, meaning FexNi9-xS8, where x is a variable number between 0 and 9. Sometimes a mineral with variable composition is split into separate species, more or less arbitrarily, forming a mineral group; that is the case of the silicates CaxMgyFe2-x-ySiO4, the olivine group. Besides the essential chemical composition and crystal structure, the description of a mineral species usually includes its common physical properties such as habit, hardness, lustre, diaphaneity, colour, streak, tenacity, cleavage, fracture, parting, specific gravity, magnetism, fluorescence, radioactivity, as well as its taste or smell and its reaction to acid. Minerals are classified by key chemical constituents; the two dominant systems are the Dana classification and the Strunz classification. Silicate minerals comprise approximately 90% of the Earth's crust. Other important mineral groups include the native elements, sulfides, oxides, halides, carbonates, sulfates, and phosphates.

1. Minerals

   Native, inorganic or fossilized organic substances having a definite chemical composition and formed by inorganic reactions. They may occur as individual crystals or may be disseminated in some other mineral or rock.

Examples of Minerals in a Sentence

1. Regan Bailey:

   It’s way too early to really know if use of multivitamin-minerals over time reduces the risk of cardiovascular mortality (or any other health problem or cause of death) in women, our study suggests the possibility that there is such a connection for women, which is an interesting finding but to know for sure would require a clinical trial.

2. Kevin Fox:

   The exploration space is not full of wonderful opportunities, what are we looking at? It's trite to say the battery minerals sector is attracting a lot of interest and we are obviously looking at that. We include in that copper.

3. Craig Hopp:

   At the moment, evidence to support the use of individual vitamins and minerals for treatment or prevention of chronic disease outcomes is weak, a diet high in fruits in vegetables includes [ lots of ] vitamins and minerals... and is epidemiologically associated with reduced instance of a whole host of chronic diseases.

4. Rod Schoonover:

   China, the next-door neighbor, is embarking on a very significant green energy development program, lithium and the rare earths are so far irreplaceable because of their density and physical properties. Those minerals factor into their long-term plans.

5. Brad Singer:

   Lava flows are ideal recorders of the magnetic field. They have a lot of iron-bearing minerals, and when they cool, they lock in the direction of the field, but it's a spotty record. No volcanoes are erupting continuously. So we're relying on careful field work to identify the right records.
