Compositional analyses of small lunar pyroclastic deposits using Clementine multispectral data
Clementine ultraviolet-visible (UVVIS) data are used to examine the compositions of 18 pyroclastic deposits (15 small, three large) at 13 sites on the Moon. Compositional variations among pyroclastic deposits largely result from differing amounts of new basaltic (or juvenile) matehal and reworked local matehal entrained in their ejecta upon eruption. Characterization of pyroclastic deposit comp...
متن کاملCompositional analyses of lunar pyroclastic deposits
The 5-band Clementine UVVIS data at 100 m/pixel were used to examine the compositions of 75 large and small lunar pyroclastic deposits (LPDs), and these were compared to representative lunar maria and highlands deposits. Results show that the albedo, spectral color, and inferred composition of most LPDs are similar to those of low-titanium, mature lunar maria. These LPDs may have consisted larg...
متن کاملRemote Sensing of Lunar Pyroclastic Mantling Deposits
Mantling deposits on the Moon are considered to be pyroclastic units emplaced on the lunar surface as a result of explosive fire fountaining. These pyroclastic units are characterized as having low albedos, having smooth fine-textured surfaces, and consisting in part of homogeneous, Febearing volcanic glass and partially crystallized spheres. Mantling units exhibit low returns on depolarized 3....
متن کاملWater in Lunar Pyroclastic Deposits : Linking Orbital Observations To
Introduction: Water (OH and/or H2O) on the lunar surface and preserved in lunar materials can record information about solar wind, cosmic ray, impact, and lunar interior processes. In particular, understanding if any lunar surface hydration signatures can be linked to endogenous (e.g., magmatic) sources has the potential to inform us of the nature and distribution of volatiles in the lunar inte...
متن کاملRadiative Transfer Modeling of Compositions of Lunar Pyroclastic Deposits
Introduction: While over 100 lunar pyroclastic deposits have been identified remotely [1], their compositions remain poorly constrained. In this work, we attempt to determine the compositions of three lunar pyroclastic deposits for which we have high-quality spectra: the Aristarchus Plateau, Mare Humorum, and Sulpicius Gallus [2]. The spectral behavior of lunar pyroclastic deposits is a combina...
