“…The best documented is the Eberswalde Crater fan delta whose distributary network has been exposed by eolian erosion (Malin and Edgett, 2003;Moore et al, 2003;Jerolmack et al, 2004;Bhattacharya et al, 2005;Lewis and Aharonson, 2006;Wood, 2006). Other examples are presented by Ori et al (2000), Howard et al (2005), Irwin et al (2005b), Di Achille et al (2006, and Weitz et al (2006). Most of the clear examples of deltas occur in just a few craters at the distal end of sparse incised valley networks that appear to have been incised during short terminal period of fluvial activity on Mars, probably about 3.7 b.y.…”

“…Included in this group are the Esberwalde Delta (Malin and Edgett, 2003;Moore et al, 2003), Holden Crater (Grant and Parker, 2002;Pondrelli et al, 2005), a series of craters in Memnomia (Ori et al, 2000), a group of craters in Arabia (McGill, 2002) and some of those identified originally by Cabrol and Grin (1999). In addition, there are interpreted deltas within individual craters from Moore and Howard (2005), Williams and Edgett (2005), Fassett and Head (2005), Mangold and Ansan (2006), and Weitz et al (2006).…”

“…Thus, the initial fl ows would carve channels through the lobes. Hence, the presence of a channel cutting through the terraced fan of Di Achille et al (2006) and Weitz et al (2006) is evidence for a minor second event after the lake level dropped. However, the absence of channels dissecting the lobes indicates that there was no second event Kraal et al, 2008), unless the second event entirely covered the smaller delta of a smaller fi rst event, but, again, this can be tested with straightforward experiments.…”

“…Furthermore the rate of percolation in craters that are not watertight ('leaky cauldrons'), would modify aggradation and progradation as well as delta morphology and is relatively easy to explore experimentally. Depending on further progress, the origin of lobed fans such as described in Irwin et al (2005), Di Achille et al (2006) and Weitz et al (2006) can be reinterpreted as deltaic.…”

Deltas on planet Mars record past climate, but so far a wide range of hypotheses for their formation have been proposed. The objective of this paper is to understand martian fan deltas, their formative conditions, evolution and formative duration, and implications for the past climate.As an introduction to Mars, physiographic provinces are described and unambiguous proof is listed for the presence of fl owing water in the past, such as certain minerals, groundwater, catastrophic outfl ow channels, alluvial fans and fan deltas, distributary networks and glaciers. The climate history of Mars differs from that of Earth by having had much drier conditions than on Earth, extreme intermittency and extreme events, most of them billions of years ago.Tens of fan deltas, unchannelized fan deltas and stepped fans have been found in impact crater and other lakes. The stepped fans were likely formed by backstepping under fast rising lake levels and have no known terrestrial equivalent. The fan deltas were formed once the lake overfl owed. Alluvial fans are much more numerous and formed with less water.The delta studies illustrate how major challenges of martian morphology and reconstruction of past conditions can be taken up most effectively by combinations of the available high-resolution images and digital elevation models, terrestrial analogues, laboratory experiments and physics-based models gleaned from geomorphology.To resolve formative mechanisms and time scale of martian fans and deltas, morphological distinctions between dense debris fl ows and dilute fl uvial fl ows must be identifi ed for both source and sink areas. Furthermore, the properties of the martian surface material are very poorly constrained but can be explored by modelling various mass wasting, fl uvial and glacial phenomena and hydrology, and by experimentation with slightly cohesive sediment. Finally, the highly debated role of groundwater sapping in valley and delta formation on Mars should be explored experimentally.
