Abstract

A new occurence of orbiculitic rocks from the Western Zillertal Alps is investigated. The orbicules consist of a core and a shell. The core is poor in potassium feldspar and rich in quartz and biotite. The shell consists mainly of potassium feldspar. Three chemical analyses. The shell consists mainly analyses, and thirty-one modal analyses were carried out. It is concluded that the orbicules have been derived from xenoliths by a partial melting process.
