Immobile trace elements classify the rocks as calc-alkaline with dominantly andesitic to basaltic-andesitic composition. Using a major element classification schemes, the least altered rocks lie in the fields for slightly alkaline rocks (monzonite and monzodiorite), while younger post-mineral felsic dykes plot in the granodiorite to granite fields). High LOI data fall mostly in basalt and andesite – basaltic andesite and alkali basalt fields.
