Hornblende (general formula Ca 2 Mg 4 (Al,Fe 3 +)(Al,Si) 8 O 22 (OH) 2), a member of the amphibole group, is a major-rock forming mineral found in high concentrations in intermediate igneous rocks, e.g., diorite, as well as medium- to high-grade metamorphic rocks (e.g., amphibolite facies), especially in mafic/ultramafic protoliths. Hornblende does not usually occur as a major mineral in the sedimentary …
