Text Description: Hornblende gabbro inclusion composed dominantly (40%) of zoned plagioclase (An90-18) and calcic augite (30%). Opacitized pargasite (23%) and euhedral and interstitial titaniferous magnetite (7%) are the other phases present. The plagioclases are laminated, and the texture of the inclusion is probably the result of cumulus processes.
