Hi George,
I couldn't get the comment block to open up on the excellent 'Clayton's
craters' post. But these structures go to the question you've posed there.
I think we are looking at a mixture of both volcanism, and impact scars.
Which means it is going to be a long time before we can come up with a
conclusive answer.
But if it's ok to give one's best guess, for these, I'll lean towards a very
large, multiple fragment impact storm a only few thousand years ago. Most
likely a broken up, icy comet. Unfortunately, the target zone was an ancient
volcanic field. So that any otherwise conclusive evidence of impacts is
going to be contaminated with solid evidence of volcanism, and visa versa.
But consider that the Sphinx was buried up to his neck in the sands of the
Sahara until modern archeologists dug him out. And then mentally subtract
the windblown sands from those images of over-lapping ring-walled
structures. That place might always be an enigma. But I don't believe those
blast burnt facies are anywhere near as old as they say.
The weakest link in standard landform theory is in the time honored, 19th
century practice of doing geo-chronology by mutual inter-assumptive
uniformitarian confabulation. If the age of those rocks wasn't arrived at by
modern radiometric methods, I just ain't buying it. And I remain to be
convinced of the dependability of some of those methods as well, when a
large airburst event is suspected.
Firestone, and friends cited Toon et al in the 2007 paper, when they
proposed temps as high as 10^7 deg. C. in the Younger Dryas impacts. That's
ten million degrees folks. But then they just drifted right on past the
significance of the energies such temps describe. And although they didn't
ask them, that figure begs questions for the plasma physicists. How do we
expect matter to behave when we elevate its temp so high that all of the
electrons, and protons, are stripped from the nuclei?
First of all, and probably most important, is that no matter what it is in
its cooler state, it is now a completely ionized thermal plasma. And it is a
superconductor. Its heat flows electrically. Such a plasma can be contained
by magnetic fields. Even those generated by its own electrical currents. So
it self-organizes into actual structures like beams, filaments, and double
layers. In short, the stuff can be expected to behave almost like a thing
alive.
And those twisting filaments of thermal plasma should bear a startling
resemblance to the ancient descriptions of fire breathing dragons with
breath so hot it can melt stone.
Google the work of Anthony Peratt, at Los Alamos National Lab for extensive
experimental research into electric plasma phenomena. And a detailed
explanation of compelling evidence that ancient peoples all over the world
have witnessed very high energy plasma events in the skies above, and left
drawings of what they saw in ancient rock art on every continent.

The powerful magnetic fields of the twisted pairs of filaments that can
organize and form in such a plasma can produce intense synchrotron
radiation. And that's where the radiometric data becomes questionable.
Because of the potential for random ion implantation anomalies, especially
anywhere a large plasma discharge event has hit the ground. (the center of
of an airburst impact vortice is a superconducting plasma)
When I asked Bill Napier what he thought of all that, he replied the he had
a problem with the ten million degree figure that Toon et al provided. He
pointed out that even if we bring a bolide in at 30 km/sec, and we translate
100% of the kinetic energy into heat in the atmosphere, we still only get
somewhere in the neighborhood of 100,000 deg C. But he also noted that even
at the more conservative temp. we are still talking about a very
'substantial plasma'. At that time it hadn't quite dawned on me in that in a
multiple fragment, airburst event, only the first pieces fall into cold
atmosphere. The rest fall into already superheated impact plasma, and just
crank up the heat and pressure. The higher figure described in the Firestone
paper doesn't seem such a stretch when you look at it in that light. Either
way, it's time to re-think the standard model of an impact event.
As for how much we don't know, consider this: On the other side of the
world, in central Mexico we find the pristine Chihuahuan ignimbrites
deposited in a continuous, random colliding, inter-flowing sheet of high
speed, fluid density currents. The standard model for a density current or
pyroclastic flow, requires a slope to flow down to provide the motive force.
Most of that stuff is on fairly level ground. So gravity wasn't the motive
force there. It also requires a volcanic vent and magma chamber to account
for the material. And the heat and pressure to get the melted rock, and
breccias into atmospheric suspension. No such rifting vent, or related
supergiant magma chamber has ever been found to account for the nearly
50,000 sq miles of continuous interflowing ignimbrites. And yet except for a
short stretch of 60 miles or so along the Chihuahua City-El Paso highway,
they've never even been mapped.
Let's put the questions of the source of the materials, or heat, and
pressure, aside for a moment. A 50,000 sq mile pristine, continuous,
interflowing density current of flash melted stone, undisturbed on the
surface, describes a geologically recent explosive event so vast that it
makes the worst Yellowstone or Toba can throw at us seem like a mouse
breaking wind by comparison. And yet no one has ever really bothered to ask
just what the hell happen there. We really don't know anything about those
materials, or the surreal landforms that rise among them beyond speculation.
And that's only just across the border, folks.
