On coming in contact with water, olivine undergoes a chemical reaction that consumes oxygen and locks it up with the water.
That doesn't make sense, Wang said, because olivine usually crystallizes early and the titanium-rich ilmenite crystallizes late.

The rocks are composed of olivine 70%, orthopyroxene 15%, clinopyroxene (mainly diopside [En 47- 49] 5% to10%), and spinel 2%.
In the process, olivine turns into the mineral serpentine and water splits into its components, hydrogen and oxygen.
Olivine and spinel are common components of asteroids and meteorites, and have been found on the floors and around the central peaks of lunar craters like Copernicus, Theophilus and Tycho that are around 100 kilometers (63 miles) in diameter.

Objectives of this study include: 1) determining mineral composition of olivine, clinopyroxene, and orthopyroxene in the xenoliths; 2) examining individual chemical zoning characteristics or orthopyroxene, clinopyroxene, and olivine; 3) comparing mineral chemistry and zoning differences between xenoliths from different eruption styles; and 4) use xenolith compositions to determine lithospheric mantle pressure and temperature.
Furthermore, minerals common to both series (chromite, olivine, augite, plagioclase, magnetite and ilmenite) are compositionally distinct reflecting fundamental chemical differences between the two magma series.
