Recurrence rate and magma effusion rate for the latest volcanism on Arsia Mons, Mars

DOI: 10.1016/j.epsl.2016.10.040 Bibcode: 2017E&PSL.458..170R

Richardson, Jacob A.; Wilson, James A.; Connor, Charles B. +2 more

Magmatism and volcanism have evolved the Martian lithosphere, surface, and climate throughout the history of Mars. Constraining the rates of magma generation and timing of volcanism on the surface clarifies the ways in which magma and volcanic activity have shaped these Martian systems. The ages of lava flows on other planets are often estimated u…

Surface roughness of Titan's hydrocarbon seas

DOI: 10.1016/j.epsl.2017.06.007 Bibcode: 2017E&PSL.474...20G

Lorenz, Ralph D.; Cassini Radar Team; Elachi, Charles +6 more

We derive fields of solutions for the surface properties (roughness and permittivity) of the liquid hydrocarbon bodies Ligeia, Kraken and Punga Mare on Titan by applying the Radar Statistical Reconnaissance (RSR) technique to the Cassini RADAR observations in altimeter mode during the northern early summer. At the time of observation, Kraken and L…

Global permittivity mapping of the Martian surface from SHARAD

DOI: 10.1016/j.epsl.2017.01.012 Bibcode: 2017E&PSL.462...55C

Mège, Daniel; Gurgurewicz, Joanna; Castaldo, Luigi +2 more

SHARAD is a subsurface sounding radar aboard NASA's Mars Reconnaissance Orbiter, capable of detecting dielectric discontinuities in the subsurface caused by compositional and/or structural changes. Echoes coming from the surface contain information on geometric properties at metre scale and on the permittivity of the upper layers of the Martian cr…

The Acheron Dorsum on Mars: A novel interpretation of its linear depressions and a model for its evolution

DOI: 10.1016/j.epsl.2017.02.019 Bibcode: 2017E&PSL.465...92D

Martino, Salvatore; De Blasio, Fabio Vittorio

The Acheron Dorsum north of Olympus Mons on Mars is a unique 800 km-long arcuate ridge apparently unrelated to other adjacent morphologies. Acheron Dorsum is crossed by deep and wide fractures ("fossae", here referred to also as Linear Depressions or "LDs"), commonly interpreted as grabens formed by local lithosphere stress in response to endogeno…

Origins of volatile elements (H, C, N, noble gases) on Earth and Mars in light of recent results from the ROSETTA cometary mission

DOI: 10.1016/j.epsl.2016.02.031 Bibcode: 2016E&PSL.441...91M

Mousis, Olivier; Morbidelli, Alessandro; Altwegg, Kathrin +6 more

Recent measurements of the volatile composition of the coma of Comet 67P/Churyumov-Gerasimenko (hereafter 67P) allow constraints to be set on the origin of volatile elements (water, carbon, nitrogen, noble gases) in inner planets' atmospheres. Analyses by the ROSINA mass spectrometry system onboard the Rosetta spacecraft indicate that 67P ice has …

Eskers in a complete, wet-based glacial system in the Phlegra Montes region, Mars

DOI: 10.1016/j.epsl.2015.09.023 Bibcode: 2015E&PSL.431...96G

Balme, Matthew; Gallagher, Colman

Although glacial landsystems produced under warm/wet based conditions are very common on Earth, even here, observations of subglacial landforms such as eskers emerging from extant glaciers are rare. This paper describes a system of sinuous ridges emerging from the in situ but now degraded piedmont terminus of a Late Amazonian-aged (∼150 Ma) glacie…
