Some of the beaches there are of a greenish colour, because of the olivine sand resulting from picrite basalt lavas.
2.
Dependent upon various regional locations, the NAIP is made up of MORB ( Mid Ocean Ridge Basalt ), alkali basalt, tholeiitic basalt, and picrite basalt.
3.
Picrite basalt is found in the lavas of Mauna Kea and Mauna Loa in Hawaii, Cura�ao, in the Piton de la Fournaise volcano on R�union Island and various other oceanic island volcanoes.
4.
The olivine-rich picrite basalts that occur with the more common tholeiitic basalts of K + lauea and other volcanoes of the Hawaiian Islands are the result of accumulation of olivine crystals either in a portion of the magma chamber or in a caldera lava lake.
