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 ...
The Mineralogical Record was first published in 1970, on the initiative of John S. White, a curator in the Smithsonian Institution's Department of Mineralogy, with the aim of filling the gap between scientific mineralogy journals (which began at that time to look more like solid state physics and chemistry than conventional descriptive mineralogy) and purely amateur magazines.

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.
The journal was established in 1916, with the first issue appearing in July of that year, under the auspices of the Philadelphia Mineralogical Society, the New York Mineralogical Club, and the Mineral Collectors' Association. On December 30, 1919, the Mineralogical Society of America was formed and American Mineralogist became the society's ...
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 .
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 ...

These minerals are found in high-grade metamorphic banded iron formation and form a compositional series between Mn 2 Mg 5 Si 8 O 22 (OH) 2 (tirodite) and Mn 2 Fe 5 Si 8 O 22 (OH) 2 (dannemorite). Calcium, sodium and potassium concentrations in cummingtonite are low. Cummingtonite tends toward more calcium substitution than related anthophyllite.
