The Pololu lavas are largely olivine basalt, and to a minor extent ba salt and picrite-basalt. The Hawi lavas are predominantly oligoclase andesite, with less abundant trachyte. Coarse grained inclusions of gabbro, dunite, and augite-hypersthene peridotite are present. Differentiation was largely or entirely by crystal settling.

20.05.2014After 45 days of reaction, 56 wt % of the initial MgO had reacted with CO2 to form Fe-bearing magnesite, (Mg0.8Fe0.2)CO3, along with minor calcium carbonates. The substantial decrease in olivine content upon carbonation supports the idea that ferroan magnesite formation mainly follows from olivine dissolution.

Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134–141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].
