May be cut smoothly with a knife. Relatively few minerals are sectile. Sectility is a form of tenacity and can be used to distinguish minerals of similar appearance. [2] Gold, for example, is sectile but pyrite ("fool's gold") is not.
A few minerals such as calcite and kyanite have a hardness that depends significantly on direction. [9]: 254–255 Hardness can also be measured on an absolute scale using a sclerometer; compared to the absolute scale, the Mohs scale is nonlinear. [8]: 52 Tenacity refers to the way a mineral behaves, when it is broken, crushed, bent or torn.
Sectility is the ability of a mineral to be cut into thin pieces with a knife. [1] Minerals that are not sectile will be broken into rougher pieces when cut. Metals and paper are sectile. Sectility can be used to distinguish minerals of similar appearance, and is a form of tenacity. [2] For example, gold is sectile but pyrite ("fool's gold") is ...
Tenacity may refer to: Tenacity (psychology), having persistence in purpose; Tenacity (mineralogy) a mineral's resistance to breaking or deformation; Tenacity (herbicide), a brand name for a selective herbicide; Tenacity (textile strength) Tenacity (audio editor), an Audacity fork; Tenacity (non-profit), an organization founded by Ned Eames
Corundum is a crystalline form of aluminium oxide (Al 2 O 3) typically containing traces of iron, titanium, vanadium, and chromium. [3] [4] It is a rock-forming mineral.It is a naturally transparent material, but can have different colors depending on the presence of transition metal impurities in its crystalline structure. [7]
Reviews in Mineralogy and Geochemistry is the official review journal of the Mineralogical Society of America and The Geochemical Society. It was established in 1974 as Mineralogical Society of America Short Course Notes and renamed to Reviews in Mineralogy in 1980. It obtained its present name in 2000.
Contributions to Mineralogy and Petrology is a peer-reviewed scientific journal published by Springer Science+Business Media since 1947. The journal is a hybrid open-access journal . The journal covers the fields of igneous and metamorphic petrology , geochemistry , and mineralogy .
In mineralogy, the type specimen, also known as type material, is a reference sample by which a mineral is defined. [1] Similar to the biology type methods, a mineral type specimen is a sample (or in some cases a group of samples) of a mineral to which the scientific name of that mineral is formally attached. In other words, a type specimen is ...
