The rarity of a mineral is determined by various factors including the specific geological conditions required for its formation the limited geographic regions where it can be found and the difficulty in extracting and processing it These factors contribute to the mineral s scarcity driving up its market value In some cases these minerals are so rare that only a
Which mineral property is the least useful for identifying minerals and why View Available Hint s a Streak is the least useful property for identification because it does not work for minerals with metallic lusters b Color is the least useful property for identification because it is the most obvious property c Streak is the least useful property for identification as the same mineral

Barite barites or heavy spar a white yellow blue red or colorless mineral It is a sulfate of barium BaSO 4 found in nature as tabular crystals or in granular or massive form and has a high specific gravity The mineral is widely distributed throughout the world It often occurs in veins with lead and zinc minerals
After successful mineral exploits in South Africa he thought that the rand belt stretched up to Zimbabwe and thus he sought a mineral concession from Lobengula the King of the Ndebele s Thus the colonisation of Zimbabwe began as the King was tricked into signing the treaty by putting an X mark which signified the beginning of white
Bauxite is a sedimentary rock mineral that is the primary source of aluminum It is formed through the weathering of aluminum rich rocks in tropical and subtropical regions The name bauxite is derived from the French village of Les Baux where it was first discovered in 1821 by geologist Pierre Berthier Bauxite is typically found in layers beneath a few meters of
The photos above Figure show examples of different mineral habits Habit a property closely related to crystal shape includes shape and size of crystal faces how forms combine how well developed different forms are and the way multiple crystals grow thus is the characteristic appearance a mineral can have
Minerals that are the same color may have a different colored streak Many minerals such as the quartz in the Figure above do not have streak To check streak scrape the mineral across an unglazed porcelain plate Figure below Why do we need to check for more than one property in mineral identification A mineral s appearance helps
This mineral is mostly found in Utah Arizona Nevada Montana Peru China New Mexico and Australia Gold Gold is considered as one of the most valuable minerals on Earth This mineral is used in making jewelries medicines artwork and even dentistry Additionally this mineral is also used as the standard currency
A mineral that contains a useful amount of a particular element like iron is classified as an ore Ores are concentrated deposits of valuable minerals and are economically significant for extraction In contrast industrial minerals and gem bearing minerals serve different purposes and classifications Explanation Classification of Minerals
Alignment of clays micas graphite or other platy minerals the separation of a rock into light and dark layers or parallel fracturing leads to planar fabrics called photo on the right above Figure shows foliation vertical fracture traces that cuts across a bedding plane separating older and youger rock layers of different compositions
The Meguma Terrane of Nova Scotia An Example of How Index Minerals Are Used The southern and southwestern parts of Nova Scotia were regionally metamorphosed during the Devonian Acadian Orogeny around 400 Ma when a relatively small continental block—the Meguma Terrane Figure top —collided with the existing eastern margin of North America
1 Felsic Igneous Rocks Definition Felsic rocks are rich in silica over 65% and contain a high proportion of lighter minerals like quartz and term felsic derives from feldspar and silica Characteristics These rocks are generally light in color ranging from white to pink or light have a high content of aluminum potassium and sodium
Garnet refers to a group of minerals that share a common crystal structure but come in a variety of colors and compositions These minerals belong to the nesosilicate family and have a general chemical formula of X3Y2 SiO4 3 where X and Y are elements that can vary The most commonly found garnets are typically red to reddish brown in color but they can also
Discover 9 common minerals with surprising uses in everyday products from table salt and pencil leads to drywall and soap Learn how rocks and minerals end up in your home Chalk A Useful Fossil Chalk is a soft porous form of limestone used historically for writing but also as a building material abrasive and source of quicklime
Mining the Environment and Politics; A mineral deposit is a place in Earth s crust where geologic processes have concentrated one or more minerals at greater abundance than in the average crust An ore deposit is a mineral deposit that can be produced to make a profit Thus all ore deposits are mineral deposits but the reverse is not true Many factors control the profitability
Development of deposits of useful minerals involves a system of organizational engineering measures for extracting minerals from the Earth s interior Deposits of commercial minerals are accumulations of mineral substances at the Earth s surf ace or interior that are suitable for industrial development in their amounts
It promotes material water and energy efficiency to reduce the environmental footprint of mineral based product life cycles GM allows the recovery of all useful minerals and minimises mining waste
The world of modern electronics is powered by a remarkable array of minerals each contributing its unique properties to the intricate tapestry of technological advancement These minerals often hidden beneath the Earth s surface play a pivotal role in shaping the devices and innovations that have become indispensable parts of our daily lives From the
A mineral deposit is a place in Earth s crust where geologic processes have concentrated one or more minerals but not pyrite or pyrrhotite Diagrams such as the one in this box Figure are useful ways to describe complex mineral relationships without words and we use them to predict and interpret ore deposit mineralogy
