“…Ares Valles and the Kasei Valles and Echus Chasma system have been suggested to share this episodic behavior, but at a much earlier time in martian history (Warner et al, 2009;Chapman et al, 2010), indicating that Mangala Valles represents a younger expression of what may be a similar subsurface process. Detailed comparative studies of other more recently active fluvial-volcanic systems, such as Athabasca Valles (Jaeger et al, 2007(Jaeger et al, , 2010, may aid in determining the extent to which repeated fluvial and volcanic activity has extended into the Amazonian Period. Comparing the timing and global distribution of these events may also provide insight into whether or not this activity has occurred within isolated systems, or has instead been associated with high-volume, planetary-scale volcanic pulses (Anderson et al, 2001;Wilson et al, 2001;Neukum et al, 2010).…”

A new mapping-based study of the 900-km-long Mangala Valles outflow system was motivated by the availability of new high-resolution images and continued debates about the roles of water and lava in outflow channels on Mars. This study uses photogeologic analysis, geomorphic surface mapping, cratering statistics, and relative stratigraphy. Results show that Mangala Valles underwent at least two episodes of fluvial activity and at least three episodes of volcanic activity during the Late Amazonian. The occurrence of scoured bedrock at the base of the mapped stratigraphy, in addition to evidence provided by crater retention ages, suggests that fluvial activity preceded the deposition of two of the volcanic units. Crater counts performed at 30 locations throughout the area have allowed us to construct the following timeline: (1) formation of Noachian Highlands and possible initial flooding event(s) before ~1 Ga, (2) emplacement of Tharsis lava flows in the valley from ~700 to 1000 Ma, (3) a megaflooding event at ~700-800 Ma sourced from Mangala Fossa, (4) valley fill by a sequence of lava flows sourced from Mangala Fossa ~400-500 Ma, (5) another megaflooding event from ~400 Ma, (6) a final phase of volcanism sourced from Mangala Fossa ~300-350 Ma, and (7) emplacement of eolian sedimentary deposits in the northern portion of the valley ~300 Ma. These results are consistent with alternating episodes of aqueous flooding and volcanism in the valles. This pattern of geologic activity is similar to that of other outflow systems, such as Kasei Valles, suggesting that there is a recurring, and perhaps coupled, nature of these processes on Mars.

“…In addition, Keszthelyi et al (2004) observed that Icelandic lava flows have a similar surface morphology to the PRP terrain. Jaeger et al (2007Jaeger et al ( , 2010) also supported the idea that the PRP terrain was formed by a thin layer of solidified lava. Currently, the origin of the PRP terrain remains debated (see reviews by Page, 2010), and the debate is open-ended because it is closely related to the Mars climate in recent geologic time.…”

Commission VI, WG VI/4KEY WORDS: Mars, Elysium Planitia, platy-ridged-polygonized terrain, mud flow ABSTRACT:The origin of the platy-ridged-polygonized (PRP) terrains on Martian surface has long been debated. The terrain has generally been classified as water, pack ice, or basalt lava related flow. The crater counting results of the PRP terrains suggest they are geologically very young; therefore, they are significant in understanding the recent evolution of Mars. This work evaluated the current hypotheses through detailed analysis of the distribution and microtopographies with the High Resolution Imaging Science Experiment (HiRISE) images for the PRP terrains in Elysium Planitia, Mars. Quantitative measurements and statistics of the typical features of the PRP terrains were also made. In addition, we also found an analog site in Tarim Basin in Xinjiang, China. Our results suggest that mud flow is responsible for the formation of the PRP terrains on the Mars surface, although the hypothesis of low-viscosity basalt lava floods cannot be completely excluded. This finding implies that a regional environment suitable for liquid water may have existed in recent geologic time, which has great importance for future Mars scientific exploration.

“…A beak-shaped radar-bright feature (21-K) agrees closely with the mapped extent of this smaller basin and is consistent with the debouching of rough-surfaced Cerberus Palus lavas from the spillway (21-G). The maps of Vaucher et al (2009a) and Jaeger et al (2010) show a narrow lava channel extending from the southern tip of this feature to a small pond basin at 139°E, 5°N; this channel and basin are referred to, respectively, as the ''western lava path'' and ''western lava basin'' in Vaucher et al (2009a) Keszthelyi et al, 2010;Balme et al, 2011). This moderate brightness also extends north of Lethe Basin and across the plains separating the northern and southern branches of Athabasca Valles.…”

“…Athabasca Valles is one of several radar-bright channels in Elysium that appear to have been cut by fissure-fed water and/or lava flows and then filled with flood lavas (Burr et al, 2002a,b;Berman and Hartmann, 2002;Plescia, 2003b;Lanagan, 2004;Jaeger et al, 2007Jaeger et al, , 2010Hurwitz and Head, 2012).

“…Jaeger et al (2010) have some of the Cerberus Palus lavas exiting the basin through a spillway (21-G) in the southwest and spreading out into a second basin. A beak-shaped radar-bright feature (21-K) agrees closely with the mapped extent of this smaller basin and is consistent with the debouching of rough-surfaced Cerberus Palus lavas from the spillway (21-G).…”
