Summary:

Named for Kaimuki spur [hill about mi N of Diamond Head, Honolulu 7.5' quad] Island of Oahu. Sketch map of Diamond Head area shows extent. Composed of basalt which varies from dense rock nearly free from vesicles to very scoriaceous material with abundant cavities 2 cm in diameter. Is strewn with rough, pitted blocks weathered to deep red color. Overlies Diamond Head tuff. Younger than Diamond Head tuff.

Summary:

Kaimuki basalt of Wentworth (1926) is called Kaimuki volcanics and included as unit in middle part of Honolulu volcanic series. Lava is a vesicular olivine pahoehoe basalt as much as 200 ft thick near center but only 4 to 8 ft thick at Kapahulu quarry. Underlies calcareous beach material of Waimanalo stand of sea. Apparently basalt erupted during Waipio stand of sea. Assigned middle(?) and late Pleistocene age.

Summary:

Covers area about 2 sq mi on south side of Koolau Range about 10 mi west of Makapuu Head. Type locality: Kaimuku Hill [about 1 mi north of Diamond Head [21 deg 16' 58"N, 157 deg 48' 06"W, Honolulu 7.5' quad] Island of Oahu. Underlies marine limestone of plus 25-ft [Waimanalo] stand of sea and lithified calcareous sand dunes of minus 60-ft (Waipio) stand. Assigned late Pleistocene age based on stratigraphic relations to Waipio stand of sea.
