Mars Express released an article on two distinct volcanic eruptions that have flooded an area of Mar's Daedalia Planum with lava, flowing around an elevated fragment of ancient terrain. The article is
at this link.

Ooooh, 3D picture, too.

I didn't see an article (or a link to an article) at the URL that you posted, but I guess you were referring to http://www.esa.int/Our_Activities/Space_Sc..._plains_of_Mars

Thanks for your work in sharing the results of Mars Express with us.

Sorry about the bad link. Your link certainly works fine, Tom, and is the correct one.

QUOTE (centsworth_II @ Feb 12 2014, 03:21 AM) *
Not around the crater, but I've marked what looks like flow out of the crater. Was the crater like an overflowing well?

I don't think that the ESA interpretation stands up under scrutiny and I have to support OWW's contention that the crater overlays a pre-existing water flow structure. The terrain slopes from left to right which fits the flow indications across the image. It is hard to accept that an impact creating a 20 kilometre crater could melt huge volumes of ice hundreds of kilometres away so the flow indicators alone deny the crater as a source. I suspect that the apparent crater overflow features you marked reflect elements of the pre-existing flow structure that presented a weaker barrier to the crater surge. A depositional rather than erosional feature.

This is Cool!!

Impact crater or Supervolcano?

This seems like a good place to put this. Maybe it deserves its own topic. I would love see some discussion.

Quote: "Without any doubt, more data and high-resolution coverage and even in situ sampling would be necessary to resolve this mystery. And since the gases released in supervolcano eruptions could have had significant effects on the martian climate, this is a topic of great interest."

The idea of supervolcanoes on Mars was new to me, but it is not new to science. A search here indicates that this has not been posted here, so here a couple of cool links from results that were published in Nature in 2013.

NASA Release: Mars Crater May Actually be a Supervolcano

Nature Release: Giant depressions may be ancient eruptions

I found this really cool video from Nature. Supervolcanoes on Mars

This seems to be a wonderful example of research on Mars increasing the understanding of our own planet.
