Summary:

Black Point basalt. Chiefly basalt and tuff. Thickness about 6 feet. Composes Black Point (promontory), Island of Oahu, Hawaii. Included in middle part of Honolulu volcanic series [q.v.]. Overlies Diamond Head tuff. Underlies calcareous beach sediments of Waimanalo stand of sea. Assigned to middle(?) and late Pleistocene Waipio stand of sea based on stratigraphic relations. [Age is considered late Pleistocene.]
[Type locality not designated.] Named from Black Point [Kupikipikio Point], on southeast side of Diamond Head, which consists chiefly of this lava, [Honolulu 7.5-min quadrangle, Honolulu Co.], Island of Oahu, HI. Exposed 40+ acres on south side of island, 9.5 mi west of Makapuu Head.
[GNC remark (ca. 1935, US geologic names lexicon, USGS Bull. 896, Kupikipikio entry p. 1123): Same as Kupikipikio basalt of Wentworth, 1926 (Bernice P. Bishop Mus. Bull., no. 30, Pyroclastic geology of Oahu). The meaning of Kupikipikio is Black Point.]

Summary:

Pg. 78. Black Point basalt. Thin lava flow of nepheline basanite, 6 to 25 feet thick, and associated dike of similar composition. Rests on reef limestone correlated with plus 95-foot (Kaena) stand of sea, and on Diamond Head tuff. Overlain by beach limestone of plus 25-foot (Waimanalo) stand of sea. No fossils. Age is considered late Pleistocene, based on stratigraphic relations.
Exposed over about 40 acres on south side of Island of Oahu, 9.5 mi west of Makapuu Head.

Summary:

K-Ar ages on basalt from Black Point Basalt of Honolulu Volcanic Series is 0.48 +/-0.08 Ma. (K-Ar ages of Gramlich and others (1971) were recalculated to be 0.302 +/-0.005 Ma based on decay constants used in this study).

Summary:

Black Point Basalt (Stearns, IN Stearns and Vaksvik, 1935) abandoned as formal unit and called Black Point flow, informal unit in Honolulu Volcanics. Honolulu Volcanics assigned Pleistocene and Holocene(?) age. [Age of Black Point Basalt most likely Pleistocene based on isotopic dating by earlier authors.]
