Mineralogical and chemical properties inversed from 21-lunar …
网页2021年7月29日 · We report on the mineralogical and chemical properties of materials investigated by the lunar rover Yutu-2, which landed on the Von Kármán crater in the pre-Nectarian South Pole–Aitken (SPA ...
Lunar mare TiO2 abundances estimated from UV/Vis reflectance
网页2017年11月1日 · 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
网页2024年3月26日 · 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 ...
网页2010年2月4日 · 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.
网页TiO 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 …
网页2012年9月26日 · 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 …
Estimate of Lunar TiO2 and FeO with M3 Data | SpringerLink
网页2023年1月1日 · 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 ...
网页2006年12月15日 · 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 ...
网页2011年7月1日 · 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 ...
网页1998年2月1日 · 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.
