Lavas recovered from Bowie seamount range from alkalic
basalt and basanite through hawaiite, mugearite and benmoreite (Engel et al.
The steep pattern with a negative slope is characteristic of alkalic
basalts produced by partial melting of garnet bearing material (Ragland, 1989), where the HREE are retained in garnet relative to LREE.

Two suites, or collections of magmas, known as alkalic
and subalkalic, can be distinguished on the basis of their alkali content ([Na.

hypabyssal and volcanic rocks at Cripple Creek, Colorado.
The postshield volcanic lavas and tephra underlying the three older sites are considered more alkalic
(higher content of basic cations) than the shield-stage lavas and tephra (Clague and Dalrymple 1989) upon which the two youngest sites have developed.
These rocks were coevally (simultaneously) intruded by granitic rocks of alkalic
(syenite) and calc-alkalic
(quartz monzonite) compositions.
