LUNAR ORIENTALE BASIN: NATURE OF IMPACT MELT AND VOLCANIC FLOODING FROM CHANDRAYAAN-1 (M3, TMC, HySI)
Introduction: Many impact basins on the Moon are filled with extensive mare basalts [1]. This obscures a) the primary structure of fresh basin interiors, including the nature and distribution of impact melts, and b) the nature of the early stages of the filling of basins with mare basalts. In contrast, the interior of the Orientale basin, the youngest and most well-preserved large basin on the ...
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 کاملDid the Orientale impact melt sheet undergo large-scale igneous differentiation by crystal settling?
Significant quantities of shock-induced melt are predicted to form during basin-scale impact events and may contribute substantially to compositional variation in the lunar crust through differentiation processes. Knowledge of the evolution of impact melt sheets and the cooling and crystallization processes involved is therefore important to understanding the geology and petrology of the Moon. ...
متن کاملThickness of proximal ejecta from the Orientale Basin from Lunar Orbiter Laser Altimeter (LOLA) data: Implications for multi‐ring basin formation
[1] Quantifying the ejecta distribution around large lunar basins is important to understanding the origin of basin rings, the volume of the transient cavity, the depth of sampling, and the nature of the basin formation processes. We have used newly obtained altimetry data of the Moon from the Lunar Orbiter Laser Altimeter (LOLA) instrument to estimate the thickness of ejecta in the region surr...
متن کاملPSRD: A Sample from an Ancient Sea of Impact Melt
Sophisticated computer modeling of the formation of lunar multi-ringed basins by impact indicate that substantial volumes of impact melt are produced, leading to melt bodies hundreds of kilometers in diameter and tens of kilometers deep. The impressively large bodies of magma created by the impact of a projectile 50 to 300 kilometers across might have differentiated, producing a zoned body with...
