What amazing veins. I'm irresistibly drawn to the old description of the discovery of gold in the Klondike:
"gold lying thick between flaky slabs of rock like cheese in a sandwich" Phil (reporting from LPSC) -------------------- ... because the Solar System ain't gonna map itself.

Don't underestimate the PR value of a gold discovery...

Wow indeed; that's paydirt (if we're still talking in terms of gold)!

Visible on the lower right of that last anaglyph rendering is a dimensional "bubble" of sorts that certainly has a hollowed aspect to it. And those boxy segments remind me of overhead views of Pueblo Bonito in New Mexico (http://arch.ced.berkeley.edu/kap/gallery/gal151.html). All around, this is an amazing place to be. And this is an amazing time to be witnessing all these outstanding and previously unseen views of so many distant worlds.

Absolutely spectacular, surely to be one of the highlights of the entire mission.
Speaking as a COMPLETE amateur, this looks to me like extraordinarily powerful evidence of hydrothermal activity; finding silica would presumably clinch that interpretation. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

... this looks to me like extraordinarily powerful evidence of hydrothermal activity; finding silica would presumably clinch that interpretation. I wonder, whether the dark phase of the veins are (enriched in) hematite or other ores, and whether there may be a connection to Hematite Ridge, interpreting the veins as clastic dikes filling fractures with liquids of a later epoch, and precipitating minerals. May be resolved later with data from younger layers. Short-term I'm hoping for - almost expecting - interesting elemental enrichments in the veins, and possible detection of new types of minerals (for Mars). Although I'm unsure, whether a new drilling will be approved so shortly after the previous drilling. |

Interesting -- y'all remember those things Curiosity came across early on, that looked like popped mud bubbles that had frozen into stone?
Looks to me like this formation shows one of those bubbles as an erosional remnant in the uppermost layers of what has most effectively resisted erosion, circled in red in the attached detail. I also see a lot of other little circular-to-spherical features in the remnant formation, here. Some might be the remains of small impacts, but others might well be the final remains of other of these "popped bubble" formations. -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain
