"Stony meteorites are named for their pyroxene component; for example, meteorites that have about 20 percent FeSiO3 are called Olivine bronzite chondrites, indicating that they contain Olivine and Bronzite (the magnesium-rich pyroxene) and that their structure is chondritic (composed of tiny spherical structures)."
"H-Chondrites: Of the observed chondrite falls, 38 percent are H-Chondrites. The H stands for "high-iron." This group contains 25 to 31 percent total iron by weight, with between 15 and 19 percent of the iron in the uncombined metal state"..." After the high percentage of metal, these stony meteorites are primarily composed of equal amounts of the minerals Olivine and Pyroxene. Since the Pyroxene is usually Bronzite, H-Chondrites"... are referred to as Olivine-Bronzite Chondrites.
