This lava specimen was part of a flow that entered the ocean, shattered, and released olivine to form a green sand beach on Mauna Loa's south coast, Hawaii. The heavier olivine particles separated from the other particles by the ocean currents. The green mineral olivine was concentrated to form the unusual green sand beach.
