Geology spans the minute and gigantic, from skeletonized leaves in China to water on mars

by distinct mineralogical assemblages, compatible with high temperatures (180 to 200 degrees Celsius) due to frictional heating during seismic slip. Foliated cataclasites and black gouges were also produced by laboratory friction experiments performed on host sediments at sub-seismic and seismic slip rates, respectively. The results of the study show that black gouges represent a potential diagnostic marker for seismic faulting in shallow creeping faults, thus helping to understand the time-space partitioning between aseismic and seismic behavior of faults at shallow crustal levels.


Evidence for widespread aqueous sedimentation in the northern plains of Mars
Mark R. Salvatore and Philip R. Christensen, School of Earth and Space Exploration, Arizona State University, P.O. Box 876305, Moeur Building, Room 131, 201 E. Orange Mall, Tempe, Arizona 85287-6305, USA. Published online 21 Mar. 2014; http://dx.doi.org/10.1130/G35319.1.

The massive networks of outflow channels are some of the most prominent fluvial features on Mars. However, the sedimentary deposits associated with these features have never been definitively identified due overprinting by subsequent geologic processes. This study by Mark R. Salvatore and Philip R. Christensen identifies a widespread sedimentary unit through a large portion of the martian northern lowlands by interrogating exposures in the walls of impact craters, which expose the subsurface stratigraphy. This unit, whose observed extent covers an area greater than that of Greenland, exhibits unique morphologies, spectral signatures, and associations with regional topography that all support an origin from the martian outflow channels. This is the first identification of such sedimentary deposits and the first to characterize their outcrop-scale properties. These properties all suggest that the northern lowlands of Mars served as a glo
