Summary:
Named for town of Lahaina [20 deg 52' 42"N, 156 deg 40' 57"W Lahaina 7.5' quad} west end of Island of Maui. Includes Kekaa cinder cone, Laina volcanics, Kilea volcanics, and Hele cinder cone, all on western part of west Maui. Consists of fire fountain deposits, thin flows of picritic basalt, nepheline basalts, and cinder cones. Is up to 60 ft thick (Laina volcanics). Overlies Pleistocene alluvial fan; underlies 1 to 1.5 ft of soil. Text says age is late Pleistocene or Recent but map shows middle(?) and late Pleistocene and Recent age.

Summary:
Separated from older Wailuku and Honolua volcanic series by profound erosional unconformity. Assigned Pleistocene or Recent(?) age based on lack of weathering and erosion, unconformable relationship to older lavas, and super position on gravels of probable Pleistocene age. Believed to be same age as some of late Hana volcanic series on Island of E Maui and Honolulu volcanic series on Island of Oahu.

Summary:
Lahaina Volcanic Series of Stearns and Macdonald (1942) here reduced in rank and renamed Lahaina Formation in accordance with provisions of Code [but change to conform with code had already taken place --see Clague and others (1982)] [Note: units within Lahaina Volcanic Series are not addressed]. Map shows Recent age.

Summary:
No type locality designated by original authors. Principal reference locality: Puu Laina [20 deg 53' 58"N, 156 deg 40' 16"W, Lahaina 7.5'quad, western end of Island of Maui, HI]. Kilea Volcanics and Laina Volcanics, units of Lahaina Volcanics (formerly Lahaina Volcanic Series of Stearns and Macdonald, 1942) are abandoned as formally named units, because they are of limited extent. They are called "Kilea flow and cinder cone" and "Laina flows and cinder cone", informal units of Lahaina Volcanics (of Clague and others, 1982). Assigned Pleistocene age.
