Summary

Intrusion of an adamellite with K-feldspar megacrysts into metadolerite wall-rock has produced a hybrid rock with K-feldspar porphyroblasts and quartz “ocelli” rimmed by hornblende. This indicates a high-level development of the feldspar and suggests that mafic contamination is an important factor in the genesis of the xenolith-rich porphyritic adamellite.
