Hawaiite

Hawaiite is an olivine basalt with a composition between alkali basalt and mugearite.^[1] It was first used as a name for some lavas found on the island of Hawaii.

It occurs during the later stages of volcanic activity on oceanic islands such as Hawaii,^[2] which happens to be when the alkali metals are most present.^[3]

In gemology, hawaiite is a colloquial term for Hawaii-originated peridot, which is a gem-quality form of the mineral olivine.^[4]
