MARS RECONNAISSANCE ORBITER HIRISE IMAGES
November 14, 2012
o Possible Phyllosilicate Near Margaritifer Chaos
The existence of clay minerals is especially interesting on Mars
since we want to know under what conditions these minerals formed.
Could it have been the presence of water?
o Chutes and Flows
Some of the surface material appears to have breached the crater rim
and flowed into the crater by way of chutes.
o A Streamlined Island in Athabasca Valles
Streamlined islands form by a rapid erosive flow (catastrophic flooding)
around an obstacle such as a resistant rock outcrop or surface armored
by impact ejecta.
o Only on Mars
The South Polar terrain of Mars has a landscape unlike anywhere on Earth.
