GANGES PLAIN — Kosi R. Mahananda-Tista Brahmaputra LARGE FANS Switching behavior — Kosi River avulsions — – cross entire surface of fan – average rate ~19 yr between switching events

Kosi R. avulsions Megafan distribution (n=88) on a Mars-like continent —

Megafan distribution in Africa’s basin-swell context.

2.4 Swell margins: single-margin (i.e. larger) basins ―

– fan distribution along basin 3.3 2.5 circumferences 1 – large fans at variable altitudes – on swell flanks mainly 2.3 – sometimes on basin floors 2.2 – diamond-shaped fans more frequent

3.2 2.1 – clusters of fans in the T/T pattern

2.7 Rifts: smaller double-margin basins —

– most fans and fan clusters within rifted lowlands 3.1 – occasionally on swell crests — 3.5 Salamat fan (Central African Rep.) Modern and paleo-megafans Sudd, Africa’s largest – triangle-shaped fans more frequent Possible megafans Rifts all contain smaller fans Unexpected conclusions —

Large fans are probably — • new class of landform feature on the planet — not the freak end point in the alluvial fan continuum • the norm in all filling continental basins -- Unexpected conclusions —

Large fans are probably — • new class of landform feature on the planet — not the freak end point in the alluvial fan continuum • the norm in all filling continental basins -- • at the poorly known middling scale the new stuff

the middling scale Unexpected conclusions —

prediction — successful prediction of location is now being performed for Earth landscapes Megafans on Mars ? ―

• Inverted channel appears to be a precise analog for widespread intercrater ridged terrain of the Crater Meridiani units (“ridge-forming unit”) to the northeast

• CRISM response — evidence for rim phyllosilicates, plus water, plus hemate upslope → ideal terrestrial condions for microbial acvity

“ … any hypothesis to explain their origin must be consistent with :

1. coherent deposition over at least the hundred kilometer scale P 2. exposures of these units over hundreds P of thousands of square kilometers 3. generally planar strata P 4. developed conformally to the (likely) preexisting shallow regional slope P 5. formation beginning toward the end of the epoch and continuing into P the 6. geographical association with both older and younger valley networks P ? 7. lack of evidence that deposition took N/A place in closed basins 8. significant physical compositional
