Veins bearing titanian andradite were found in a metasomatically altered clinopyroxenite cumulate of an alkali magmatic suite (Little Dromedary, NSW, Australia). The titanian andradite is up to 2.5 cm in size, mainly subhedral and displays a large concentric, oscillatory intergrowth with layers consisting of plagioclase and alkali feldspar. Detailed field work and petrography showed that there is a gradual change in paragenesis from the cumulitic clinopyroxenite with interstitial plagioclase to...[Show more]
