In mineralogy, tenacity is a mineral's behavior when deformed or broken. Common terms. Brittleness. The mineral breaks or powders easily. Most ionic-bonded minerals ...
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.
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
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 ...
A school of mines (or mining school) is an engineering school, often established in the 18th and 19th centuries, that originally focused on mining engineering and applied science. Most have been integrated within larger constructs such as mineral engineering , some no longer focusing primarily on mining subjects, while retaining the name.

Spinel (/ s p ɪ ˈ n ɛ l, ˈ s p ɪ n əl / [7]) is the magnesium/aluminium member of the larger spinel group of minerals. It has the formula MgAl 2 O 4 in the cubic crystal system. Its name comes from the Latin word spinella, a diminutive form of spine, in reference to its pointed crystals. [5]
Goslarite is a hydrated zinc sulfate mineral (ZnSO 4 · 7 H 2 O) which was first found in the Rammelsberg mine, Goslar, Harz, Germany. It was described in 1847. It was described in 1847. Goslarite belongs to the epsomite group which also includes epsomite ( MgSO 4 · 7 H 2 O ) and morenosite ( NiSO 4 · 7 H 2 O ).
