Summary:
Named for Paniau hill. Type locality at E side of Paniau hill [21 deg 56' 21"N, 160 deg 04' 59"W] forming remnant of shield volcano on Island of Niihau, HI. Composed of thin-bedded vesicular olivine basalts of both aa and pahoehoe type, beds of vitric lapilli ash, and basaltic dikes. Maximum exposed thickness is 1281 ft at type locality. Underlies with erosional unconformity Kiekie volcanic series. Map plate and cross section show overlying sedimentary rocks of recent age inland and in valleys. Age is given as Pliocene(?).

Summary:
Paniau Volcanic Series of Stearns (1947) is reduced in rank and renamed Paniau Basalt to reflect composition of basalt. Unpublished K-Ar data for 11 flows of Paniau indicate Miocene and Pliocene age (G.B. Dalrymple, oral commun., 1986).
