Model for the origin, ascent, and eruption of lunar picritic magmas
A model for the origin, ascent, and eruption of the lunar A17 orange glass magma has been constructed using petrological constraints from gas solubility experiments and from analyses of the lunar sample 74220 to better determine the nature and origin of this unique explosive eruption. Three stages of the eruption have been identified. Stage 1 of the eruption model extends from ~550 km, the A17 ...
متن کاملA Revised Model for the Ascent and Eruption of Gas-saturated Lunar Picritic
Introduction: Prior to the discovery of H2O dissolved in the picritic lunar glass beads [1], models for the eruption of lunar picritic magmas involved both a column of melt extending deep into the lunar mantle, and a gas-assisted lift of the magma to achieve explosive eruption [2,3,4,5]. In a H-free moon, first gas phase formation would have involved the oxidation of reduced C (graphite) to pro...
متن کاملWe model the ascent and eruption of lunar mare basalt magmas with new data on crustal
48 We model the ascent and eruption of lunar mare basalt magmas with new data on crustal 49 thickness and density (GRAIL), magma properties, and surface topography, morphology and 50 structure (Lunar Reconnaissance Orbiter). GRAIL recently measured the broad spatial variation 51 of the bulk density structure of the crust of the Moon. Comparing this with the densities of lunar 52 basaltic and pi...
متن کاملThe Behavior of Thorium in Lunar Picritic Magmas: Implications for the Bulk Thorium Content of the Lunar Mantle and Lunar Heat Flow
Introduction: Previous studies of heat flow from the lunar mantle have suggested that the amount of heat flow is strongly dependent on the abundance of radioactive isotopes in the mantle and is at least loosely correlated with Th content [1,2]. Measurements of heat flow from the Apollo missions had been used to imply that those measurements could be extended outside of KREEP terrains; however, ...
متن کاملthe use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach
abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...
