Basaltic Pyroclastic Deposits on Earth and Mars: Constraints for Robotic Exploration of Martian Pyroclastic Deposits
Introduction: Basaltic pyroclastic rocks are uncommon on Earth because most mafic magmas are too volatile-poor to drive explosive eruptions [3-4]. However, basaltic pyroclastic deposits maybe much more common on Mars than on Earth [4-7] because Mars’ lower gravity and thinner atmosphere permit explosive eruptions from magmas with lower volatile contents. Though rare, basaltic pyroclastic rock o...
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 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 کاملLunar Pyroclastic Deposits and the Origin of the Moon 1
Debate over the origin and evolution of the Moon, and implications relative to the Earth, has remained lively and productive since the last human exploration of that small planet in 1972. More recently, issues related to the evolution of Mars, Venus and Mercury have received increasing attention from the planetary geology community and the public as many robotic missions have augmented the earl...
متن کاملDeep submarine pyroclastic eruptions: theory and predicted landforms and deposits
Submarine pyroclastic eruptions at depths greater than a few hundred meters are generally considered to be rare or absent because the pressure of the overlying water column is sufficient to suppress juvenile gas exsolution so that magmatic disruption and pyroclastic activity do not occur. Consideration of detailed models of the ascent and eruption of magma in a range of sea floor environments s...
