Good afternoon Folks,

I was looking at a 2 mm part slice of Park Forest today under the microscope
and saw something rather unusual. In an area several mm wide of almost solid
metal there was a circular area about 1 mm wide of small whitish crystals. I
flipped the specimen over and the metal and crystal structure apparently goes
through to the other side of the specimen. Looks almost like a tube of
crystals surrounded by metal.

Do any of you have any idea what I am looking at? Here is a link to some of
the photomicrographs I took of the anomaly:

Thanks in advance for your educated guesses.

Best Regards,

Paul
