About Manganbabingtonite
Formula:
Ca2(Mn,Fe)FeSi5O14(OH)
Colour:
Dark greenish black to yellowish green
Hardness:
6½ - 7
Specific Gravity:
3.452
Crystal System:
Triclinic
Name:
Named for being the manganese dominant analogue of babingtonite. The root name is in honor of Dr. William Babington (21 May 1756, Portglenone, near Coleraine, County Antrim, Northern Ireland, UK - 29 April 1833, London, England, UK), physician and mineralogist, curator of the John Stuart, 3rd Earl of Bute mineral collection until 1792, founding member and President (from 1822 to 1824) of the Geological Society of London and author of noted systematic books on mineralogy (1796, 1799).
