 The study examined two types of olivine from the Hawaiian Mauna Loa and Kilauea volcanoes, which have different compositions and spectroscopic properties. One variety has a lower iron content of 10 to 12 mole percent, while the other has a higher iron content of 18 to 21.5 mole percent. Both varieties also contain chrome spinelides, which correspond to subfor allium acromite and subfor is a valium acromite. These mineralogical features suggest that they originate from the mantle, as do the rocks of the urals alpine type. This article was authored by A.B. Mekiev, V.P. Lutoev, I.P. Vtorov, and others.
