About Ferro-hornblende
Formula:
◻Ca2(Fe2+4Al)(Si7Al)O22(OH)2
Defined as an amphibole in the magnesio-hornblende group of the Calcium subgroup with Fe2+>Mg and Al>Fe3+ in the C position and (OH) as the dominant ion in the W position.
Colour:
Dark green to black, greenish-brown, more rarely lighter green
Lustre:
Vitreous
Hardness:
5 - 6
Specific Gravity:
3.12 - 3.30
Crystal System:
Monoclinic
Member of:
Name:
Named in 1789 by Abraham Gottlieb Werner from an old German term for dark minerals with no ore value and from "blende", meaning to deceive in allusion to it occurring in ore deposits but not yielding any metal and for ferro- indicating Fe2+ as a dominant cation.
