It is an isomorphous mixture of three molecules; a calcium-iron-magnesium silicate, and aluminium-iron-magnesium silicate, and an iron-magnesium silicate. Manganese, titanium, and Sodium are sometimes present. Fluorine substitutes for the hydroxyl in the structure. The general formula can be given as (Ca,Na)2–3(Mg,Fe,Al)5(Al,Si)8O22(OH,F)2. Hornblende has a hardness of 5–6, a specific gravity of 2.9–3.4 and is typically an opaque green, greenish-brown, brown or black color. Its cleavage angles are at 56 and 124 degrees. It is the principal mineral of amphibolites. Very dark brown to black hornblendes that contain titanium are ordinarily called basaltic hornblende.

  • Hornblende was a mineral composed of a mixture of three different silicate molecules. It was found in the explosive mineral formations on Gamma Trianguli VI, mixed with uraninite and quartz. It was also a component of granite. (TOS: "The Apple" )
  • Hornblende is a mineral that is a part of the Amphibole group of minerals. It is a double-chained inosilicate that is typically dark in colour.
