About CummingtoniteHide

Formula:
β—»{Mg2}{Mg5}(Si8O22)(OH)2
Cummingtonite is defined as a monoclinic amphibole belong to the magnesium-iron-manganese amphibole subgroup.
It is defined with Mg as the dominant element both in the B and C positions.
Colour:
Translucent dark green, brown, grey, colourless
Lustre:
Vitreous
Hardness:
5 - 6
Specific Gravity:
3.1 - 3.6
Crystal System:
Monoclinic
Name:
Cummingtonite was originally named in 1824 by Chester Dewey for the type locality in Cummington, Massachusetts, USA. Dewey (1824) did not analyze the species, but noted its unusual physical appearance. Actual physical description and chemical analyses for cummingtonite were provided by Thomson (1831) and subsequently improved by Smith and Brush (1853). Leake (1978) published a report assigning cummingtonite the wide range Mg/Mg + Fe = 0.3-0.7. In 2006, Hawthorne and Oberti published new boundaries between cummingtonite and grunerite at Mg:Fe2+ = 1:1.
