Magnesiohornblende (Magnesio-hornblende), a calcium magnesium aluminum silicate hydroxide mineral of the amphibole group, has been found in several specimens from Sterling Hill; it has not been reported from Franklin. It occurs as dark green, massive material with titanite and calcite from the 1140 crosscut, on the 1500 level and as dark brown ...

Magnesio-hornblende
Crudely formed magnesiohornblende crystals and masses in white calcite. Also present but hard to discern is a very dark green-black mica, probably phlogopite. From Excalibur Mineral Co. with EDS ID, see child image for spectrum and analysis, corresponds to magnesiohornblende with significant Zn and Mn substitution.

Effective reverse flotation separation of siderite from …
Magnesiohornblende is a typical Mg-Fe-Al-bearing silicate mineral, often associated with siderite [4]. It consists of a basic skeleton of interlocking double chains of silica-oxygen tetrahedra, in which some of the Si atoms are replaced by Al atoms and the interstices of the double chains are filled with different metal ions (e.g., iron ...
