Abstract
The lavas of the volcanic Leeward Hawaiian Islands, including Niihau, Nihoa, Necker, La Perouse, and Gardner, are predominantly, if not entirely, basaltic. Assuming that the specimens studied by us are representative, andesine basalt is comparatively rare, olivine-free labradorite basalt is more abundant, olivine-labradorite basalt is most common, and picrite basalt is somewhat less so. One specimen of nephelitic basalt and one of limburgitic basalt were found. There seem to be no andesites and no trachytic rocks or oligoclasite. The general facies is one of decidedly femic rocks, low in silica and alkalies, with high lime and very high magnesia and iron oxides. Titanium is high, but phosphorus is low. There appears to be an increase westward in olivine, as well as in magnesia and titanium, with a concomitant decrease in silica.
