“…The results presented here corroborate other studies that advocate a late magmatic insurgence in the Ladon basin. Following the experimental results obtained by Luzzi et al (2021), the general radial and concentric distribution of grabens centered at the western part of the basin, as well as their T and Y-shaped junctions, would testify to such a late magmatic activity causing oblate extension and diffused fissure eruptions. Similarly, the abundance of FFCs in the close vicinity of the East Ladon study area (Figure 2) would testify to the nearby emplacement of magmatic bodies, whether sills or laccoliths, which could share a common magmatic source with Units 1-3 in this work.…”

“…For this reason, similar to the Moon (Jozwiak et al, 2014), magma intrusion and subsequent crater floor uplift might be a cause for FFC formation even in the absence of groundwater or ice (Bamberg et al, 2014). Luzzi et al (2021) suggested that FFC fracturing could result from a succession of magmatic inflation and deflation episodes.…”

The evolution of the Ladon basin has been marked by intense geological activity and the discharge of huge volumes of water from the Martian highlands to the lowlands in the late Noachian and Hesperian. We explore the potential of the ExoMars Trace Gas Orbiter/Color and Stereo Surface Imaging System color image data set for geological interpretation and show that it is particularly effective for geologic mapping in combination with other data sets such as HiRISE, Context, and Compact Reconnaissance Imaging Spectrometer for Mars. The study area displays dark lobate flows of upper Hesperian to early Amazonian age, which were likely extruded from a regional extensional fault network. Spectral analysis suggests that these flows and the underlying rocks are ultramafic. Two distinct altered levels are observed below the lobate flows. The upper, yellow‐orange level shows hundreds of structurally controlled narrow ridges reminiscent of ridges of listwanite, a suite of silicified, fracture‐controlled silica‐carbonate rocks derived from an ultramafic source and from serpentine. In addition to serpentinite, the detected mineral assemblages may include chlorite, carbonates, and talc. Kaolin minerals are detected in the lower, white level, which could have formed by groundwater alteration of plagioclase in the volcanic pile. Volcanism, tectonics, hydrothermal activity, and kaolinization are interpreted to be coeval, with hydrothermal activity and kaolinization controlled by the interactions between the aquifer and the hot, ultramafic lobate flows. Following our interpretations, East Ladon may host the first listwanite ridges described on Mars, involving a hydrothermal system rooted in a Hesperian aquifer and affecting ultramafic rocks from a magmatic source yet to be identified.

“…(2016) found that more segmented faults show a lower D max / L ratio, while individual fault segments accumulated more displacement for a given fault length, and this could be due either to an advanced maturity in the fault's evolution or to the fact that such fault grew in isolation and had no chances of linkage; Finally, in case where the fault experiences a reactivation in the opposite sense of slip (and this would be the case if we assume both the inflation first proposed by P. H. Schultz (1976), and the piecemeal caldera collapse suggested by Luzzi et al. (2021)), reverse faults reactivated as normal can show lower values of D max / L ratios (Kim & Sanderson, 2005). …”

“…Several types of terrains and thus landforms are peculiar to specific areas or even planets or moons. For instance, Chaotic Terrains are planetary surface features notably found on Mars, Mercury, Jupiter's moon Europa and Pluto (Luzzi et al, 2020(Luzzi et al, , 2021Skjetne et al, 2021). Mountains, hills, plains volcanoes are common in almost all rocky planets of the Solar System (Hargitai & Kereszturi, 2015).…”

The exploration of terrestrial planets in the Solar System was and still is performed mainly on data that cover almost all the electromagnetic spectrum, acquired over the last century by several types of orbiters, rovers, and landers. Planetary data volumes are constantly increasing both in quality and quantity, with the contribution of both public and private entities.Imagery has always been the primary resource for researchers in planetary sciences, especially for geologists and geomorphologists. In the last two decades, the progress in the development of very high-resolution image sensors gave the community access to images with a spatial resolution on the order of centimeters. Data collected by High Resolution Imaging Science Experiment (HiRISE) instrument, on board of the Mars Reconnaissance Orbiter (MRO) (McEwen et al., 2007) or by the Narrow Angle Camera experiment, on board of Lunar Reconnaissance Orbiter (Robinson et al., 2010), have been used in several works to constrain the surface properties of respectively, Mars and the Moon.
