Title Tectono-magmatic, sedimentary and hydrothermal history of Arsinoes and Pyrrhae Chaos, Mars Publication Type Journal Article Year of Publication 2020 Authors Luzzi E, Rossi APio, Carli C, Altieri F Journal Submitted for publication in Journal of Geophysical Research : Planets Abstract
Arsinoes and Pyrrhae Chaos are two adjacent chaotic terrains located east to Valles Marineris and west to Arabia Terra, on Mars. In this work we produced a morpho-stratigraphic map of the area, characterized by a volcanic bedrock disrupted into polygonal mesas and knobs (Chaotic Terrain Unit) and two non-disrupted units interpreted as sedimentary and presenting a spectral variation, likely associated to hydrated minerals. The reconstructed geological history of the area starts with the collapse that caused the formation of the chaotic terrains. Since volcano-tectonic evidences are widespread all-over the area (e.g. fissure vents/graben, radial and concentric systems of faults, y-shaped conjunctions, lava flows, pit chains), and an intricate system of lava conduits is hypothesized for the occurrence of such features, we propose the possibility that the whole collapse was caused primarily by volcano-tectonic processes. On Earth, polygonal blocks and systems of concentric + radial fissures are originated in the frame of a particular caldera collapse called chaotic or piecemeal. In the study area on Mars, the chaotic collapse would have been triggered by repeated inflation and deflation of a putative magma chamber in depth under the terrain. In a late stage, after the end of the volcano-tectonic activity, a lacustrine/evaporitic depositional environment could have set, with the deposition of the non-disrupted units. The hydrated minerals found in the periphery of the Chaos could be the result of hydrothermal alteration of the basaltic bedrock.

Title Abundance and size-frequency distributions of boulders in Linne crater's ejecta (Moon) Publication Type Journal Article Year of Publication 2018 Authors Pajola M, Pozzobon R, Lucchetti A, Rossato S, Baratti E, Galluzzi V, Cremonese G Journal arXiv:1812.00590 [astro-ph] Date Published dec Keywords Astrophysics - Earth and Planetary Astrophysics Abstract
This paper presents the abundances and the size-frequency distributions (SFD) of the ejected boulders surrounding the Linne crater, located on the Moon's Mare Serenitatis basin. By means of Lunar Reconnaissance Orbiter Camera high-resolution images we prepare a context geological map of the Linne crater as well as we identify 12000 boulders > 4.4 m, with a maximum measured size of 30.8 m. The cumulative number of boulders per km2 is fitted with a power-law curve with index -4.03 +0.09/-0.10. By studying the radial ejecta abundances, we find that the largest ones are located within the first 2 km from the crater's centre, while few tens of boulders with sizes < 8 m are detectable above 5 km from the crater's rim. We find that the Linne proximal ejecta blanket is slightly asymmetrical, as indicated in the geological map too, showing a density increase in the NE-SW direction. This may be the result of an oblique impact emplacement of the original impactor, or it may be explained with a perpendicular impact in the Mare Serenitatis location, but on a surface with lunar basalts with different local mechanical properties. By exploiting our boulders size density as a function of the distance from the crater's centre, we derive a possible regolith thickness at the Linne impact of 4.75 m, supporting similar values based on Earth-based radar and optical data in the Mare Serenitatis basin.
