A mineral is a naturally occurring substance, representable by a chemical formula, that is usually solid and inorganic, and has a crystal structure. It is different from a rock, which can be an aggregate of minerals or non-minerals and does not have a specific chemical composition. The exact definition of a mineral is under debate, especially with respect to the requirement a valid species be abiogenic, and to a lesser extent with regard to it having an ordered atomic structure. The study of minerals is called mineralogy.
There are over 5,300 known mineral species; over 5,070 of these have been approved by the International Mineralogical Association (IMA). The silicate minerals compose over 90% of the Earth's crust. The diversity and abundance of mineral species is controlled by the Earth's chemistry. Silicon and oxygen constitute approximately 75% of the Earth's crust, which translates directly into the predominance of silicate minerals. Minerals are distinguished by various chemical and physical properties. Differences in chemical composition and crystal structure distinguish various species, and these properties in turn are influenced by the mineral's geological environment of formation. Changes in the temperature, pressure, or bulk composition of a rock mass cause changes in its minerals.

Rock and Mineral (geology) - July 22, 1996
Here are the 13 most rare and valuable gemstones and minerals ever seen in the world like the blye Benitoite and red diamonds! Subscribe for new videos Monday Wednesday and Friday! 8. Jeremejevite This mineral was discovered way back in 1883 by a French mineralogist named Augustin Alexis Damour, who named it after the Russian scientist Pavel Vladimirovich Eremeev. The crystal was found on Mt. Soktui in Siberia, Russia. Since then, it has been described as being found in the Eifel District of Germany and in the Pamir Mountains in Namibia. This rare aluminum borate mineral is comprised of variable hydroxide and fluoride ions. 7. Poudretteite This mineral was first found during the mid-1960’s in the Poudrette quarry of Mont Saint-Hilaire, Quebec. However, it wasn’t until 1987 that the...

Episode 1 introduces the concept of a mineral. Minerals are defined by five criteria; 1) They must be solid substances 2) they must be naturally-occurring 3) they must have a definable chemical composition 4) they must have an orderly crystalline structure 5) they must be inorganic by nature. The video introduces mineral properties using common fruit and vegetables as analogies for these five descriptive criteria. The video also demonstrates the orderly crystalline structure of halite (NaCl) using a model made of food (marshmallows and grapes). Comparisons between common substances such as ice and glass versus the mineral definition are made to illustrate the specific nature of the mineral definition.
A mineral is a “naturally occurring substance that is solid and inorganic representable by a chemical formula, and has an ordered atomic structure.” Rocks, unlike minerals, don’t have a specific chemical composition, and can be made of both minerals or non-minerals. Although there are over 4,900 known types of minerals, the ones here are just a small sample of beauty our planet has to offer. Without further adieu,let your eyes feast on some of the world’s most beautiful minerals and stones straight from Mother Earth. And they say diamond’s are a girls best friend…not anymore!
The steps used to identify minerals
Here is a song I created to help my 6th grade students study. I hope you enjoy. Minerals have special properties To help identify, observe it Observe, identify it These minerals, they're naturally occurring Inorganic solids, crystal shape Elements always the same Minerals To classify it as, it must be Found in the crust, but naturally But you know it is so, inorganic not plant and trees Animals once living, minerals then it can't be A mineral is always solid It has definite volume And you know that you should know And here we go Minerals line up so Making crystals shape strong Faces, edges, corners hold With elements made of atoms Same chemical and physical Making composition But most are made of the minerals Are made up of a compound Two or more elements they're no longer alone Dissol...
