Mare Basalt Fragments in Lunar Highlands Meteorites: Connecting Measured Ti Abundances with Orbital
Lunar highland meteorites contain small proportions of mare basalt fragments, which are important for defining lunar basalts in areas not visited by Apollo/Luna. We analyzed seven mare basalt fragments from three highland meteorites, and retrieved the Ti contents of their parent magmas from core pyroxene compositions. The analyzed clasts span the range of VLT and low-Ti, basalts in Apollo & Lun...
متن کاملPetrologic Comparisons of Lunar Mare Basalt Meteorites Dh-287A and NWA
Introduction: It is intriguing that the majority of lunar meteorites (~30) have been discovered in the hot deserts of Middle-East and North Africa. In contrast, of 10s of thousands of meteorite finds from Antarctica over 30 years, only a handful (~5) are lunar. This bias towards the lunar meteorite recovery from the hot deserts may be due to the preferential fall of lunar meteorites in these re...
متن کاملInvestigating the water contents and hydrogen isotopic compositions of lunar apatite
The initial studies of Apollo rock samples concluded that the Moon was an anhydrous planetary body [1]. Recently there has been a change of opinion with several research groups detecting copious amounts of water, up to 6050 ppm from a range of lunar glasses, melt inclusions and apatite [2-7]. Here we report results from insitu ion microprobe analysis of apatite grains from Apollo mare basalt 12...
متن کاملLunar mare deposits associated with the Orientale impact basin: New insights into mineralogy, history, mode of emplacement, and relation to Orientale Basin evolution from Moon Mineralogy Mapper (M) data from Chandrayaan‐1
[1] Moon Mineralogy Mapper (M) image and spectral reflectance data are combined to analyze mare basalt units in and adjacent to the Orientale multiring impact basin. Models are assessed for the relationships between basin formation and mare basalt emplacement. Mare basalt emplacement on the western nearside limb began prior to the Orientale event as evidenced by the presence of cryptomaria. The...
متن کاملVisible/near Infrared Spectral Characterization of Brecciated Mare Basalt Flow and Surface Mare Basalt
Introduction: Lunar mare basalts are products of partial melting of the lunar interior, thus are keys to understand the chemical compositions of the source mantle. However, the iron-enrichment of the mare basalt samples returned by Apollo and Luna missions, compared to the terrestrial basalts, have led to an inference that the mare basalt hand specimen do not represent the primary magma composi...
