About Ferro-hornblendeHide

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:

Hornblende Root Name Group > Calcium Amphibole Subgroup > w(OH, F, Cl)-dominant Amphibole Group > Amphibole Supergroup

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.

Forms a series with magnesio-hornblende.
