Detailed description

Orbiculare Texturen, d.h. konzentrisch zonierte sphärische Strukturen gibt es in vielen Gesteinen. Die Zusammensetzung schwankt zwischen Diorit und Granit. In Australien z.B. erscheinen die Rundungen in einer Granodiorit-Matrix. Sie bestehen aus Andesin, Plagioklas, Hornblende und Biotit, welche um einen Kern aus Plagioklas und/ oder Hornblende angeordnet sind oder seltener in mafischem Schiefer.
Siehe auch unter Kugeldiorit.
