Don't mean to compete against the Home Sweet Home thread, but I thought I'd put together a summary of the main observations and points discussed so far with regard to Home Plate, especially now that the thread is almost 20 pages long. I wouldn't be surprised that even after we eventually get the spectroscopy data, we'll probably still have a way to go before we get a handle on the origin of Home Plate.

So, anyways, I hope everybody finds the post of some use. The link is on my homepage.

Cheers,
Aldo.

Thanks. I don't know if english speaking geologists call this a cauliflower bomb, but everybody will catch the image and see how these bombs will look like.

These bombs form when a quantity of lava is quickly mixed with water, a thing which of course results in a large explosion. This happens in submarine strombolian activity, but also in maars, when the lava climbs through a watertable, or when a stream pours into the maar. It is these explosions which form the maar and project debris and ashes far away, so that maars often have no rims.



NEW UPDATE ON THE NASA SITE AND STILL NO ANALYSIS RESULTS.

... a cauliflower bomb

Back when I was rude and crude I might have made a joke about this, but no more!
Tell me, Richard (is my pronunciation - Reeshard - correct?) can you tell me something about the pioneer, Faget. His name has been given to one of the rocky exposures on McCool Hill. I know Korolev but not Faget (Fajay? I hope) TIA

Shaka: In a way the HP deposits are related to an impact structure in that they accumulated in a depression caused by an earlier impact and were preserved by the protection this low area provided.\While on speculations, are the scattered chunks of viscicular basalt associated with a thin flow at a later time or are they air -fall erratics associated with a volcanic eruption. Mainly because of their distribution, I am inclined to think they are ejecta but would it not require a different vent source from the HP volcanics because of a their mafic composition??

Neb, (do you spell your name backwards in the yellow forum?), I'm pleased to see that you are keeping the faith on our impact postulate. You would agree that if we could core down far enough we would find suevite, breccia, shatter cones, PDFs - the whole box-and-dice?. (It might be hard to find a place on Mars where you wouldn't, right?) If these spongebob rocks went flying up into the air, would they come down looking this good, and in a non-random distribution? Why is it that, try as I might, I just can't see the vesicular, vacuolar, styrofoam structure of the laminated cross-bedded upper unit of HP?? I look at it, and all I see is sandstone! http://marsrovers.jpl.nasa.gov/gallery/all...A0P2956M2M1.JPG
I see lots of little bumps, and under each bump is a partly-rounded, dark grain of "olivine-rich basalt", bound up with a lighter matrix that, apparently, is not sulfate. Why don't I see more openings, exposed on the surface, to all these vacuoles? Some of us used to think that this unit was like Eldorado well steeped in brine and then dried. Why am I the only one left who thinks that?
Your guidance is appreciated, and, if Tim Denko is reading, yours also.
