Abstract
The rocks of Tahiti constitute what is probably the most complete suite of strongly alkaline rocks in the Pacific Ocean. New analytical and petrographic data show that the differentiated rocks form two divergent series. Each series is represented by a wide range of effusive and plutonic rocks that differ mainly in their relative degree of silica enrichment. The end members of one series are trachytes and syenites that are almost exactly saturated; the second series trends toward phonolites and nepheline syenites.
