Summary: Mud volcanism has been proposed as a formation mechanism for certain landforms on Mars, but data from CRISM has not been fully utilized to study these features. While specific minerals like phyllosilicates, carbonates, or sulfates were not confidently identified, hydrated glass of volcanic origin and high-Ca pyroxene were observed in Valles Marineris. Nanophase ferric oxide signatures were consistent on a global scale in CRISM visible data from mud volcano features.

Summary: The study investigated small-scale domes in western Arcadia Planitia near Tyndall crater, revealing the presence of ferrous silicate minerals and high-Ca pyroxene and glass mixtures. Spectral evidence showed absorption features consistent with Fe-bearing plagioclase and alkali feldspar, along with convexity associated with alkali-rich plagioclase or alkali feldspars on top of some domes. Morphological observations indicated a connection with ice through brain terrain material on the domes, suggesting a continuum from intrusive cryptodomes to flat extrusive domes potentially of felsic composition.

Summary: Researchers have mapped and classified unique landforms on Mars, determining that they were formed by subsurface sediment mobilization. They propose that the sediment likely originated from the same source and suggest the possibility of previously unconsidered sequences of events leading to sedimentary-volcanic activity within Adamas Labyrinthus.

Summary: This study presents geochemical evidence supporting the hypothesis of supervolcanic calderas in northwest Arabia Terra. Gravitational modeling suggests the presence of low-density pyroclastic loading and a low elastic thickness, indicating higher heat flow during eruption. The unique geochemical observations reinforce the compositional distinctiveness of this region compared to contemporaneous volcanoes.

Summary: A study suggests that the pitted cones and knobs on the surface of Mars may be formed by mud volcanism, and a quantitative color band ratio technique using HiRISE camera data can provide additional mineralogical information about these formations. The findings show that the mud materials on Mars are consistently associated with ferric minerals, indicating the presence of mud volcanism.

Summary: Volcanism has played a significant role in altering the Martian surface, with the Tharsis volcanic province displaying a variety of lava flows with similar characteristics to those on Earth. The study reveals that eruption rates, viscosities, and emplacement times are comparable between Mars and Earth, indicating the potential for ongoing localized volcanic activity on Mars.

Summary: The study of basalt clasts from the PKT returned by Chang'e-5 mission reveals that these two-billion-year-old basalts are not derived from KREEP mantle source, but produced high abundances of rare-earth elements and thorium through low-degree partial melting and extensive fractional crystallization. This suggests that the KREEP association may not be a prerequisite for young mare volcanism, indicating a more sustained cooling history of the lunar interior to generate the Moon's youngest melts.

Summary: The Von Karman crater was flooded with mare basalts during at least three main phases, forming a layer of basalt at least 320 meters thick. The compositional characteristics of the ejecta around the crater vary radially with distance, indicating possible mineral heterogeneity. The Yutu-2 rover may potentially test the hypothesis of similar sources for the mare basalts in the crater.

Summary: Carbonate minerals have been detected in the Jezero crater and the Nili Fossae region with similar properties and are likely to have a shared origin. The presence of both Mg- and Fe-rich carbonates in the region is consistent with olivine carbonation, and hydrothermal alteration is suggested as the most likely formation mechanism.

Summary: The study evaluates the capabilities of VSWIR imaging spectroscopy in the Samail Ophiolite, Oman. Findings show that VSWIR spectroscopy can be used to identify the time order of different alteration events, record rock compositions, and reflect changes in rock pressure and temperature. Spectroscopy can discriminate between carbonate and serpentine phases, as well as carbonate solid solutions.

Summary: The East African rift system is formed above mantle upwellings and the formation of rifts is related to lithospheric thinning and magmatic activity. The amount of splitting varies spatially and the fast axes are predominantly parallel to the orientation of the rifts. Thick lithospheric modules have less splitting and different orientations, which may indicate mantle plume flow. Splitting rotates and increases in strength as it enters the rift zones, suggesting that the anisotropy is mainly present at shallow depths.

Summary: Oxygen fugacity is a fundamental parameter for understanding redox processes in igneous systems. This study compares the Fe-XANES oxybarometry method with the V-in-olivine method for evaluating fO(2) in MORB lavas. The results show that the V-in-olivine method is not applicable to samples with low MgO content, and that the majority of Archean komatiite sources have lower fO(2) than modern MORB.

Summary: The volatile components CO2 and H2O play a major role in mantle melting and heterogeneity. In this study, Ca isotopes were used to trace the lithological heterogeneity in alkaline magmatic rocks. The results revealed the presence of K-richterite and carbonate components as the source of alkaline magmas with low delta 44/40Ca values. These findings highlight the importance of Ca isotopes as a robust tracer of lithological variation caused by volatiles in the Earth's upper mantle.

Summary: Although the current approach to estimate catchment-wide denudation rates using only 10Be concentrations has made significant progress in geomorphology, this study argues for the inclusion of 26Al measurements and testing of steady-state assumptions in slow eroding, formerly glaciated landscapes. The study conducted measurements of both 10Be and 26Al in stream sediments from the Vosges Massif in France and found that elevation, slope, channel steepness, and precipitation were the primary factors controlling denudation rates. The study also revealed a significant relationship between the extent of past glaciation and the cosmogenic (un-)steadiness in the stream sediments.

Summary: Numerical models of Earth's mantle dynamics can predict the vigour and mixing of mantle flow, and the average slab sinking rates are an unexplored parameter that can provide intrinsic information on these characteristics. Through numerical experiments, it has been found that slab sinking rates are strongly correlated with mantle convection and mixing, and may explain geochemical observations from hotspot volcanoes.
