[meteorite-list] Libyan (looks like a) crater

[Randy Korotev]

Dear List:

I received this intriguing e-mail today from someone I don't know.

=========================

Dear Randy, I am a geophysicist and had a recent 
trip on Libyan desert for campaign of geophysical 
investigations, mostly GPR and Geoelectric 
tomography. Going back to the camp I found at 
sunset –due to low angle light- something strange on the flat desert surface.

I found a perfect circular crater with melt sand 
scattered around . sand grains are melt and 
embedding larger quartz grains. In my opinion 
that’s a impact crater and sand is melt because 
of the heat wave. Larger grains had no time to melt .

That melt rock has a black matrix-nothing like 
that in the area, also there are no similar 
structures in that flat, flat flat  desrt 
surface, sand is only silica and quartz grain and 
no dark matrix can be seen for kilometers.

I made a few geophysics on the spot and found big 
electric anomalies and very anomalous readings of Geoelectric values.

I took a few samples of melt rock –very heavy really.

I am posting a few photos of the crater.

I have another stone found at 2500 m on the bed 
of a melt glacier, same story, that’s not a stone 
of the area, it is like a fuse, heavy and black 
inside with a very aerodynamic shape, I will mail 
you a photo ( after reading once more your 
recommendations) if interested . for sure not a 
human artifact or an original stone of the area.

Sorry to disturb,
...

I put the photos here:

The round thing in the desert looks something 
like a crater.  Maybe it's a bomb crater.  Maybe 
it's a meteorite impact crater.  The rock doesn't 
look like samples of Libyan desert glass that 
I've seen.  I don't know the LDG story well.  Has 
there ever been a crater associated with the glass?
