Hydrogen Isotopes in Lunar Volcanic Glasses and Melt

Common Water The Moon has been traditionally considered bone-dry, but in recent years a number of studies have shown that during mantle melting, the lunar mantle had as much water as Earth's upper mantle. Saal et al. (p.1317, published online 9 May; see the cover) measured the isotopic composition of hydrogen dissolved in volcanic glass and olivine-hosted melt inclusions recovered from the Get price

Millerite

Millerite is thought to form from sulfur and nickel which exist in pristine olivine in trace amounts, and which are driven out of the olivine during metamorphic processes. Magmatic olivine generally has up to ~4000 ppm Ni and up to 2500 ppm S within the crystal lattice, as contaminants and substituting for other transition metals with similar ionic radii (Fe 2+ and Mn 2+ ).

The Crust of the Moon as Seen by GRAIL

High-resolution gravity data obtained from the dual Gravity Recovery and Interior Laboratory (GRAIL) spacecraft show that the bulk density of the Moon's highlands crust is 2550 kilograms per cubic meter, substantially lower than generally assumed. When combined with remote sensing and sample data, this density implies an average crustal porosity of 12% to depths of at least a few kilometers Get price

Flotation of Chromite as Pre

Olivine is a magnesium-iron silicate (Mg, Fe) 2 SiO 4 that also contains small amounts of other minerals e.g. chromium oxide at concentration levels near 0.2 wt%. Chromium oxide is associated to iron and magnesium in the form of chromite particles which are inert during the carbonation reaction. Get price

Boom boom pow: Shock

Olivine grains throughout the Lafayette and MIL 00346 thin sections have been aqueously altered to form iddingsite veins, thus demonstrating that liquid water penetrated throughout both rocks. The more severe aqueous alteration of olivine in comparison to augite reflects the considerably greater reactivity of olivine in the presence of Martian fluids ( 31 ). Get price

The origin of eucrites, diogenites, and olivine diogenites:

If all of the olivine is concentrated in a dunite layer, this layer should be 300–500 m thick. However, it is more likely that the olivine is more diffusely distributed in thin, cryptic layers of dunite, harzburgite, and olivine diogenite accounting for 10–20% of the lower Get price

Magmatic Differentiation

Thus, as we have seen, crystallization of olivine from a basaltic liquid would eventually reach a point where olivine would react with the liquid to produce orthopyroxene. Bowen postulated that with further cooling pyroxene would react with the liquid, which by this time had become more enriched in H 2 O, to produce hornblende. Get price
