Generation of nordmarkitic melts by melting of basement gneisses: the Astrophyllite Bay complex
Acid-basic net-veined or pillowed dykes and intrusive bodies are small but important components in the felsic complexes of the Tertiary magmatic province in East Greenland. In Astrophyllite bay in the Snout Series syenite intrusion at the margin of the Kangerdlugssuaq syenite intrusion basic trachya...
