(1975) determined a K-Ar age of 0.66-0.77 m.y. for the subaerial Aitutaki
nephelinic basalt. The young volcanic flows on Aitutaki represent post- erosional
volcanism, similar to that found on other oceanic islands such as Hawaii. Wood (
1967) ...

Geological Survey Professional Paper
Lherzolite nodules are common in nephelinic basalts on Nunivak Island and
elsewhere in the world, but this is their first known occurrence in tholeiitic basalt.
They provide direct evidence that tholeiitic magma originates at mantle level ...

Jabal ArknO, a major massif which dominates the peneplained metamorphic
basement, is essentially a ring structure of nephelinic-syenitic composition and of
batholite size. Nephelinic syenites, normal syenites and phonolites are the main
lit ...

The lherzolite inclusions suggest that the nephelinic rocks originate at a greater
depth than do those of the alkalic suite. The rare inclusions of wehrlite in
nephelinic rocks may have been picked up at shallow depths, where the magma
came in ...
