Bonhommet et al. 1977

Bonhommet, N., Beeson, M.H. and Dalrymple, G.B. (1977). A contribution to the geochronology and petrology of the island of Lanai, Hawaii. Geological Society of America, Bulletin 88(9): 1,282-1,286.

Chemical analyses of four lava flows from Lanai, Hawaii confirm petrographic observations that the flows of Lanai are typical Hawaiian tholeiites, somewhat more similar in composition to those of Mauna Loa than to those of Kilauea. K-Ar analyses of six samples indicate that Lanai is 1.25+0.04 m.y. old, which is consistent with the hypothesis that the volcanoes of the Hawaiian Islands become older to the northwest from the active volcanoes of Mauna Loa and Kilauea to Kauai.
