unequivocally classify the rock into the nephelinic suite of Macdonald & Katsura (
1964) and as a nephelinite member of that suite (Macdonald 1968). Although

A similar explanation for the structures in the Arapohue rock is supported by the
presence of a slightly higher percentage of mesostasis glass, the occurrence of
zeolites, and the tendency for the nephelinite dike margins to brecciate and ...

Olivine, clinopyroxene, and feldspathoids constitute 25-60% of the exposed rocks
. There are five rock types within the Uvalde igneous field: alkali basalt, melilite-
olivine nephelinite, olivine nephelinite, nepheline basanite, and phonolite.
