Hornblende Facts and Photos

What Exactly is Hornblende?

Hornblende is a name used to describe a group of minerals which can only be distinguished through detailed chemical analysis.  For this reason all minerals in the group are generally referred to simply as hornblende.  They're important constituents in igneous and metamorphic rocks and mostly occur in dark colours such as black, dark green or brownish green. 

Hornblende minerals have no real use in industry and are mostly popular as mineral specimens.
