Lunar mare TiO2 abundances estimated from UV/Vis reflectance
WEBNov 1, 2017 · We find a wide variation of TiO 2 abundances (from 0 to 10 wt%) for early mare volcanism (>2.6 Ga), whereas only medium to high TiO 2 values (average = 6.8 wt%, minimum = 4.5 wt%) are found for younger mare units (<2.6 Ga).
Unusual Ti minerals on the Moon produced by space weathering
WEBMar 26, 2024 · In this paper, we describe the occurrence and mineralogy of space-weathering-produced titanium-oxide deposits (TiO 2 and Ti 2 O) in lunar samples. We propose that the formation mechanism of...
The titanium contents of lunar mare basalts - GIGUERE - 2000 ...
WEBFeb 4, 2010 · Abstract— Lunar mare basalt sample data suggest that there is a bimodal distribution of TiO 2 concentrations. Using a refined technique for remote determination of TiO 2, we find that the maria actually vary continuously from low to high values.
WEBTiO 2 (5wt%) and significantly higher FeO content (22.5wt%). Most mare basalts from Apollo and Luna collections have TiO 2 contents in the range 0.6–10wt%, and abundances between 5 and 6wt% are...
Refinement of lunar TiO2 analysis with multispectral features of …
WEBSep 26, 2012 · We present a SVM-SVM model for predicting TiO 2 abundance on the Moon using Chang’E-1 IIM imagery. Estimation of lunar titanium abundance is a small-sample and high-dimension issue, and SVM has been shown to work well for this type of issue.
Estimate of Lunar TiO2 and FeO with M3 Data | SpringerLink
WEBJan 1, 2023 · In the current study, visible to near-infrared reflectance data acquired by the Moon Mineralogy Mapper (M 3) on Chandrayaan-1 (Clark et al. 2010; Pieters et al. 2009; Dhingra et al. 2010) are used to investigate the FeO and TiO 2 abundance of lunar surface at global scales.
Testing the relation between UV–vis color and TiO2 content of the lunar ...
WEBDec 15, 2006 · Reflectance spectroscopy is important for placing lunar samples into a regional and global geologic context. To this end, the ultraviolet–visible (UV–vis) color ratio, used to estimate the TiO 2 composition of mature mare basalts, has been one of the most widely used spectral parameters in lunar exploration.
Preliminary results of TiO2 mapping using Imaging Interferometer data ...
WEBJul 1, 2011 · The derived TiO 2 abundances are validated with Clementine UVVIS results in several regions, including lunar highlands neighboring the Apollo 16 landing site, and high-Ti and low-Ti maria near the standard site of Mare Serenitatis (MS2).
Mapping the FeO and TiO2 content of the lunar surface with ...
WEBFeb 1, 1998 · The derivation of quantitative elemental concentrations from multispectral imaging of the Moon has long been a goal of lunar remote sensing. Concentration maps at the spatial resolutions available from the recent Clementine mission would provide a revolutionary new tool for understanding the origin and evolution of the lunar crust.
