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.. In other words, they are minerals formed as a result of biological processes. Minerals range in composition from pure elements and simple salts to very complex silicates with thousands of known forms (organic compounds are excluded). Most of the sulfides are simple structurally, exhibit high symmetry in their crystal forms, and have many of the properties of metals, including metallic lustre and electrical conductivity. The term "mineral" encompasses not only the material's chemical composition, but also the mineral's structure. Comparing their properties with the definition of a mineral. A mineral is a naturally occurring crystalline solid that cannot be physically broken down into smaller components.. Glossary of Geology (Bates and Jackson, 1980, p. 401) defines a mineral as The study of minerals is called mineralogy. A mass of rock particles, grains of minerals, or both.

They all are on the soft side, from hardness 3 to 4 on the Mohs hardness scale. Mineral strength is calculated by measuring tenacity, hardness, cleavage, and fracture. A brief treatment of mineralogy follows. Orpheus Minerals. Uses of Gold. They often are strikingly coloured and have a low hardness and a high specific gravity. Orpheus was established to explore for and discover greenfield uranium deposits in South Australia and the Northern Territory at economic grade and scale. Defining a mineral. c.

A formal definition of a mineral, as used by geologists would be: A naturally occurring inorganic solid that has a definite chemical composition, and an ordered internal structure. Gems are most commonly made of minerals. A mineral is composed of a single element or compound. Luster: The reflection of light from the surface of a mineral, described by its quality and intensity. a. Allochromatic minerals are "other colored" due to trace impurities in their composition or defects in their structure. About half of the known chemical elements possess some metallic properties. iii. Acicular means "needlelike." This mineral is actinolite. Gold has unique properties that make it one of the most useful minerals. adoption forums for . streak, the colour of a mineral in its powdered form. In this case, the color is a .

For further discussion, see geology: Study of the composition of the . The group includes kaolinite, which is chemically similar . In paleontology, dendritic mineral crystal forms are often mistaken for fossils. A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. The word mineral means different things to different people. mineral, naturally occurring homogeneous solid with a definite chemical composition and a highly ordered atomic arrangement; it is usually formed by inorganic processes. Here are some examples: Geologist's Definition. This is measured by scratching it against another substance of known hardness on the Mohs Hardness Scale. The earth is composed of mineral elements, either alone or in a myriad of combinations called compounds. b. Irregular mass of crystals. 2012 March 1, Lee A.
