An inorganic species or substance occurring in nature, having a definite chemical composition and usually a distinct crystalline form. Rocks, except certain glassy igneous forms, are either simple minerals or aggregates of minerals.
a naturally occurring chemical compound (or element) of known physical properties (which may vary within fixed limits). Minerals are usually solid, although some may be liquid (e.g.. mercury) or gaseous (e.g.. natural gas). Minerals and are usually inorganic, although some are of organic origin (e.g.. Amber, Chalk, Oil). Most minerals may exist in three states under different pressure/temperature conditions.
Any of the various naturally occurring inorganic substances, such as metals, salt, sand, stone, sulfur, and water, usually obtained from the earth. Note: For reporting on the Financial Reporting System the term also includes organic non-renewable substances that are extracted from the earth such as coal, crude oil, and natural gas.
Any of the various naturally occurring substances (such as coal, crude oil, metals, natural gas, salt, sand, stone, sulfur, and water) usually obtained from the earth. The term is used to include all wasting, i.e., non-regenerative, inorganic substances that are extracted from the earth.
a naturally occurring substance with a characteristic chemical composition (which could be expressed by a chemical formula), formed through geological processes; the term encompasses also the mineral structures. Minerals range in composition from pure elements and simple salts to very complex silicates with thousands of known forms; may occur as individual crystals or may be disseminated in some other solid substance. Note: most mineralogists include the requirements of inorganic origin and internal crystalline structure. geology
The building blocks of rocks. Minerals are the individual chemical compounds in solid, crystalline form. The common mineral types (e.g. quartz, feldspar, mica, amphibole, pyroxene, olivine, calcite, dolomite) are often referred to as the "rock-forming" minerals. Note that most of these mineral groups can be chemically complex with the proportions of the constituent elements varying.
One of about thirty relatively simple chemical substances required in the diets of all animals, including humans. Some minerals are compounds of metals (calcium, iron, sodium, potassium, magnesium, copper, manganese, and zinc). Others are compounds of nonmetals (phosphorous, iodine, sulfur, chlorine, and fluorine).
(min'-er-al) A naturally occurring, usually inorganic, solid homogenous material with a definite chemical composition variable within fixed limits and a highly ordered atomic arrangement. For a detailed explanation, see Just What Is a Mineral.
A homogenous, naturally occurring, solid inorganic substance with a definable chemical composition and an internal structure characterized by an orderly arrangement of atoms, ions, or molecules in a lattice.
(2) an inorganic substance occuring in nature, though not necessarily of inorganic origin, which has: (a) definite chemical composition or, more commonly, a characteristic range of composition, and (2) distinctive physical properties or molecular structure. (4) a naturally occuring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form and physical properties.
Naturally occurring, inorganic substance that typically has a crystalline structure. Each mineral has characteristic properties such as hardness, colour, lustre, cleavage and relative density and each has a characteristic chemical composition, e.g. the mineral quartz is silicon dioxide (SiO2). Minerals are the components of rocks.
A naturally occurring inorganic solid having a definite internal structure and a definite chemical composition that varies only within strict limits. Chemical composition and internal structure determine its physical properties, including the tendency to assume a particular geometric form (crystal form).
A naturally-occurring, solid, crystalline substance, usually inorganic, with a specific chemical composition that can vary within defined limits. Different rock types are often formed of different characteristic sets of minerals.
Inorganic salts required by aquatic organisms in moderate or trace quantities, for the correct functioning of an organism's physiological activities. Sufficient quantities of minerals are usually present in aquaculture feeds from the raw materials used. Compared to vitamins, minerals are cheap and stable and so addition of minerals to feeds does not contribute to higher feed costs
1) Any chemical element or compound occuring naturally as a product of inorganic processes. Rocks, except certain glassy forms, are either simple minerals or aggregates of two or more minerals. Such substances as coal and amber are not true minerals.
An inorganic substance ("inorganic" means without a carbon atom) found in nature that is required in small quantities for life and that is acquired through the diet, such as the minerals calcium, chromium, zinc, etc.
In a broad nontechnical sense, the term embraces all inorganic and organic substances that are extracted from the earth for use by man. A substance occurring in nature which has a definite or characteristic range of chemical composition, and distinctive physical properties or molecular structure. With few exceptions, such as opal and mercury, minerals are crystalline solids.
A naturally occurring crystalline substance. Magmas crystallise different minerals as they cool from high temperature. Common minerals in rocks include olivine, pyroxene, plagioclase, magnetite,.and hornblende. Many lavas consist of millimetre-sized phenocrysts of different minerals set in a fine groundmass, the crystals of which are only visible under a microscope.
Naturally occurring solid that has a specific chemical composition and a unique internal arrangement of its atoms. For example, quartz consists of silicon and oxygen atoms in a 1:2 ratio (SiO), and these atoms are bonded together in a hexagonal structure.
A substance that is neither animal nor plant. It is a chemical compound, usually inorganic in nature (no carbon atoms), which occurs naturally. Examples are quartz, feldspar or compounds of crystalline structure. It sometimes includes soluble "rocks" such as limestone. Ground water can dissolve all or a portion of these rocks and the minerals contained in these rocks, thus causing these minerals to be present in tap water. Certain geographic locations contain a high level of minerals which can cause staining and scale problems in pool and spa water.
A term applied to inorganic substances, such as rocks and similar matter found in the earth's strata, as opposed to organic substances such as plant and animal matter. Minerals normally have definite chemical composition and crystal structure. The term is also applied to matter derived from minerals, such as a inorganic ions found in water. The term has been incorrectly applied to ion exchangers, even though most of the modern materials are organic ion exchange resins.
Any substance that is neither animal nor vegetable. It is any class of substances occurring in nature, usually comprising of inorganic substances, such as quartz or feldspar, of definite chemical composition and definite crystal structure. It sometimes includes rocks formed by these substances. Ground water dissolves these rock substances, and the dissolved minerals are present in tap water. Depending on the kinds of rocks the water comes in contact with, the minerals dissolved in the water may be just a few or they may be many. Water hardness is mostly comprised of these minerals.
A naturally occurring chemical compound or limited mixture of chemical compounds. Minerals generally form crystals and have specific physical and chemical properties which can be used to identify them. more details...

A term applied to inorganic substances such as rocks and similar matter found in the earth strata, as opposed to organic substances such as plant and animal matter. Minerals normally have definite chemical composition and crystal structure. The term is also applied to matter derived from minerals, such as the inorganic ions found in water. The term has been applied to ion exchangers, stemming from the early use of natural zeolite. The term is inappropriate to the modern organic ion exchange resins.
Ausually inorganic substance which occurs naturally, and typically has a crystalline struc- ture, whose characteristics of hardness, lustre, color, cleavage, fracture and relative density can be used to identify it. Each mineral has a characteristic mineral composition. Rocks are composed of minerals.
minerals are the building blocks of rocks. They are naturally occurring substances, which often have a crystalline form. They can be single elements (such as gold or diamond) or compounds (such as quartz or pyrite).
a non-living, solid material with particles arranged in a repeating pattern called a crystal. A mineral is usually a combination of 2 or more elements. A mineral cannot be broken down into any other substance.
A nutrient essential in small amounts for good nutrition and health. Examples of minerals include calcium, iron, potassium, sodium, and zinc. Like vitamins, the best way for minerals to enter the body is through food.
Substances such as Calcium, Manganese, Magnesium, Nickel, Copper, Silver, Zinc, Iron, Cobalt or Aluminum. Their presence in high non-chelated concentrations can lead to stains or scale formation. The measure of water hardness is dependent on these minerals.
Vitamins and minerals are essential components in enzymes and coenzymes. Enzymes are molecules involved in speeding up chemical reactions necessary for human bodily function. Coenzymes are molecules that help the enzymes in their chemical reactions. Minerals can be classified as either bulk or trace. Bulk minerals are needed in larger amounts than trace minerals and include calcium, magnesium, sodium, potassium and phosphorus. Trace minerals are needed in only minute quantities and include boron, chromium, copper, iodine, iron, manganese, molybdenum, selenium, and zinc.
one of six types of nutrients needed to sustain life. Among other roles, minerals help keep the nervous and cardio respiratory systems functioning. The two types of miners are macrominerals (such as sodium and potassium), needed in large amounts, and trace minerals (such as zinc), needed in small amounts. Minerals are found in meat and dairy products, vegetables, fruits, grains, seeds, seafood, and salt.
A solid inorganic homogeneous crystalline substance resulting from the inorganic process of nature, with distinctive physical properties and definite chemical composition (or compositions). Also, any substance that is neither animal or vegetable.
An inorganic element found in nature though the term is usually reserved for those elements that are solid. In nutrition, the term mineral is usually used to classify those dietary elements essential to life processes. Examples are calcium and iron.
Natural inorganic substance which is either definite in chemical composition and physical characteristics or any chemical element or compound occurring naturally as a product of inorganic processes.
An inorganic fibre, natural or manufactured. Note 1: Asbestos is a naturally occurring inorganic fibre and the term 'mineral fibre' has sometimes been used to mean asbestos exclusively. Note 2: Metallicc fibres are not normally described as mineral fibres (see metallic (fibre)). (See also Classification Table, p.401.)
A nutrient required by a living organism, but one that does not supply energy. Nitrates in the soil are a source of nitrogen needed by the plant to make protein. Magnesium is a mineral needed by plants to make chlorophyll. Calcium is a mineral needed by humans for bone growth.
an inorganic substance found in nature, having a uniform or restricted chemical composition and a regular crystalline form; any natural substance obtained by mining or quarrying, such as coal, ore, salt, and stone. Gold, silver, and iron are metallic minerals; quartz, feldspar, and calcite are nonmetallic minerals. [AHDOS
A mineral is a naturally-occurring solid of definite chemical composition whose atoms usually form a regular pattern. About 4,000 different types of minerals have been identified. Each mineral has a unique chemical makeup and structure, and can be identified by its physical, structural, and optical properties (like its location, color, luster, streak, hardness, specific gravity, translucency and refraction of light).
A naturally formed, inorganic solid with a specific chemical composition and characteristic crystal structure. Examples of minerals include quartz (SiO2), salt (also called halite, NaCl), graphite (C). Rocks are formed of one or more minerals.
Inorganic elements that originate in the soil, some minerals act as nutrients. There are 16 nutrient minerals, which include calcium, copper, iodine, iron, magnesium, selenium, zinc, copper, manganese, fluoride, chromium and molybdenum. Minerals play a crucial role in the human body for enzyme creation, regulation of heart rhythm, bone formation, digestion, and other metabolic processes.
Minerals are natural compounds formed through geological processes. The term "mineral" encompasses not only the material's chemical composition, but also the mineral's structure. Minerals range in composition from pure elements and simple salts to very complex silicates with thousands of known forms (organic compounds are excluded).
Plays a vital role in regulating many body functions. They act as catalysts in nerve response, muscle contraction and the metabolism of nutrients in foods. They regulate electrolyte balance and hormonal production, and they strengthen skeletal structures.
To dream of minerals, denotes your present unpromising outlook will grow directly brighter. To walk over mineral land, signifies distress, from which you will escape and be bettered in your surroundings.
A chelated mineral is generally attached to a protein transporter molecule with the intent of improved transport across the gut to the blood stream. Although some of the minerals are well absorbed in this manner it does not necessarily always indicative of the best form for absorption.
