The Constitution and Structure of the Lunar Interior
The current state of understanding of the lunar interior is the sum of nearly four decades of work and a range of exploration programs spanning that same time period. Missions of the 1960s includingExpand

Extracting olivine (Fo–Fa) compositions from Raman spectral peak positions
The dominant feature of the olivine Raman spectrum is a doublet that occurs in the spectral region of 815–825 cm � 1 (DB1) and 838– 857 cm � 1 (DB2). These features arise from coupled symmetric andExpand

Comparative zircon U–Pb geochronology of impact melt breccias from Apollo 12 and lunar meteorite SaU 169, and implications for the age of the Imbrium impact
Abstract The ages of zircons from high-Th impact-melt breccias (IMBs) from meteorite Sayh al Uhaymir (SaU) 169 and from rock fragments in soil samples from Apollo 12 have been determined using theExpand

Sulfates on Mars: A systematic Raman spectroscopic study of hydration states of magnesium sulfates
The martian orbital and landed surface missions, OMEGA on Mar Express and the two Mars Explorations Rovers, respectively, have yielded evidence pointing to the presence of magnesium sulfates on theExpand

Northwest Africa 773: Lunar mare breccia with a shallow-formed olivine-cumulate component, inferred very-low-Ti (VLT) heritage, and a KREEP connection
Abstract Lunar meteorite Northwest Africa 773 (herein referred to as NWA773) is a breccia composed predominantly of mafic volcanic components, including a prominent igneous clast lithology. The clastExpand

Raman spectroscopy of Fe-Ti-Cr-oxides, case study: Martian meteorite EETA79001
Abstract Raman spectral features of chromite, ulvöspinel, magnetite, ilmenite, hematite, and some of their solid solutions are presented. Although most Fe-Ti-Cr-oxides produce relatively weak RamanExpand

Phase transition pathways of the hydrates of magnesium sulfate in the temperature range 50°C to 5°C: Implication for sulfates on Mars
[1] Dehydration/rehydration experiments were conducted on pure Mg-sulfates and mixtures of epsomite with Ca-sulfates, Fe-sulfates, Fe-oxide, and Fe-hydroxide. The goal was to investigate theExpand

Partitioning in REE-saturating minerals - Theory, experiment, and modelling of whitlockite, apatite, and evolution of lunar residual magmas
We present compositions, including REEs determined by ion microprobe, of apatite and whitlockite in lunar rock assemblages rich in incompatible trace elements. Total concentrations of REE oxides inExpand

Crystal chemistry of lunar merrillite and comparison to other meteoritic and planetary suites of whitlockite and merrillite
Abstract Merrillite, also known as “whitlockite„ , is one of the main phosphate minerals, along with apatite, that occur in lunar rocks, martian meteorites, and in many other groups of meteorites.Expand
