It appears they are not hematitic...

Phew - relief! The 'just blueberries' hypothesis was giving me headaches the more I tried to believe it.
QUOTE (Bill Harris @ Sep 14 2012, 04:10 AM)  This new unit is indeed interesting. [ . . . ] No doubt there will be much arm-waving and pacing of the floor going around. Not just here but at NASA too it seems. This is a big moment for sure. I hope you (UMSF geologists plural) will continue to share your arm-waving with the rest of us despite the complexity of the subject in view. |

QUOTE (marsophile @ Sep 14 2012, 09:07 PM) From Steve Squyres: "we have a wonderful geological puzzle in front of us. We have multiple working hypotheses, and we have no favorite hypothesis at this time. It's going to take a while to work this out, so the thing to do now is keep an open mind and let the rocks do the talking." I love this. We did have this kind of quote since nearly Sol 1, then once in a while but didn't have it again for years! -------------------- |

To what extent are the scientists able to work 'both sides of the field', ie sit in and contribute to both Curiosity and Opportunity SOWG meetings? Are some of them locked in on Mars time, or is that just the operations personnel? I can imagine some researchers who are tied down atm with stuff like calibrating instruments on MSL but would like to be able to assist in the planning Oppy's science campaign at this location.

Actually, this feels a lot like when Spirit arrived at the Columbia Hills and immediately found Pot of Gold rock. And Squyres said it was like starting the mission up fresh.
This feels like we're starting a new exploration all over again, here...  -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain

Luv the plaster patch.....and cool that we are not seeing another blueberries site.
Participatory explorartion at it's best..... from a guy who remembers Mariner 4, never would have imagined how we can now all be a part of this journey. Indeed a new exploration has begun..... LUV THIS!!! (Have I said that before  Craig |

Well these new "berries" are blue (at least as much as the other ones).

I vaguely remember seeing similar layers of impact spherules in the NW Australia Pilbara mining leases (longer ago than I really care to contemplate). Regardless of the formative process for the spherules the matrix seems highly resistant to aeolian erosion. This does imply aqueous alteration/strong lithification which could occur within a directly emplaced layer or through transportation and accumulation.

Just as an aside...
In the JPL release on Kirkwood, I really like the fact that the image they use is credited to: NASA/JPL-Caltech/Cornell Univ./ USGS/Modesto Junior College Looks like some enthusiastic, future UMSF'ers have been busy

One of the first things I noticed working with images from this location is that there is an excess of yellow in the raw IRB tri-color images. This is anomalous. I remember that previously I noticed this same color bias at the stop at Santa Maria Crater. At the time I thought that this crater penetrated the Burns Fm and disturbed the basal unit underlying the Burns (basal, in this case, being the geologic unit underneath the Meridiani playa deposits). At Santa Maria Oppy also encountered blue, burple and light-toned rocks of "unknown affinities" that, unfortunately, we did not have time to examine closely.
I supect that this basal unit is the pre-Endeavour surface, highly weathered and comprised of a mish-mash of various impactites, ejectites and other residual units. This may well be the source of the holy-grail phyllosilicates of which we seeketh. There are some of the Santa Maria images at my Mars photosite (listed in my Sig) --Bill -------------------- |

A nice writeup on Prof. Hagen is in the college's "Vista and Voices" news letter (pdf) at this link: (search for JPL, or Hagen) www.mjc.edu/general/president/2011springvistasvoices.pdf Congratulations to Prof.Hagen for his outstanding work! -------------------- CLA CLL

I took some times to stitch this kinda huge mosaic of these very interestings outcrops. Do this place have a name ?
Some frames are missing, they will surely be available in the next few days .
