Summary:

"This formation is restricted to the Puu Waawaa cone and to certain strata exposed in the face of the Anahulu cliff, north of the Puu Waawaa cone (Puako 15' quadrangle) [Puu Anahulu 7.5' quad]". Cone is surrounded and partly buried by Hualalai flows. Assigned Pleistocene(?) age.

Summary:

Named for Cone Puu Waawaa. Type locality Puu Waawaa on Northern slope of Hualalai Volcano, Island of Hawaii HI. Is trachyte unit of Hualalai volcanic series. Extends 6 mi to north. Exposures as much as 900 ft thick. Base not exposed. Cone and flow partly underlie and overlie basalts from Hualalai and Mauna Loa as shown in diagrammatic cross-sections. Estimated eruption of Waawaa in early and middle Pleistocene time (p.183-184).

Summary:

Mapped as trachyte of Puu Waawaa. Map shows trachytic pumice cone and lava flows as unit of Hualalai volcanic series. Assigned Pleistocene age on map.

Summary:

Name changed from Waawaa Volcanics (a unit of Hualalai Volcanic Series) to Waawaa Formation in chart only. [Evidently no longer member of Hualalai --now named "Hualalai Formation" --since both are of equal rank]. Text discusses trachyte "pumice of Puu Waawaa" and "trachyte lava flow".

Summary:

Waawaa Volcanics of Hualalai Volcanic Series of Stearns and Macdonald (1946) reduced in rank and named Waawaa Trachyte Member of Hualalai Volcanics. Name change reflects lithology. Recent unpublished K-Ar determinations by G.B. Dalrymple (oral commun., 1986) indicate 0.105 Ma. Age is Pleistocene.
