There are fragments of xenoliths in basaltic rocks of young volcanoes
from Stromboli (Italy). They are oordierite bearing bUChite, having white
colours and are in various sizes. The biggest fragment is around 20 '-"In long.
The main minerals are cordierite. Around eithy percent of rocks composed of
cordieritc and 20% consist of tridymite, hypersthene, sanidine and glass.
Microscopic studies shows that the texture is granoblastic and mosaic. The
mineral paragenesis and chemical composition indicated that the original rock
were aluminum - rich and bauKitc - rich shales. The cordierite are the Mgrich
cordierite. Xenoliths mctamophosed by sanidinitefacies.
