'Impact Pit' Pics
Hello All,
After a bit of work on his part, and no fewer than
thirty-seven emails that did or didn't get to wherever they were supposed to
go (we may never know what gets lost within the bowels of the internet...),
Jeff Kuyken was able to get a number of pics of cratered Sikhotes up onto his
site.
They're of seven Sikhote-Alins in our collection
(viz., my father's and my collection), which display pits on leading edges,
trailing edges, non-oriented irons, and in a fairly wide range of sizes.
Enjoy!
7.9g
Oriented.
Crater on trailing edge.
Diameter of crater is 3mm with a depth of
~1.5mm.
Upraised rim, and small bump visible in the bottom of
the pit itself.
54.6g
Not oriented.
Crater is approximately 2.5mm across and about
2mm deep.
Upraised rim.
77.7g
Not oriented.
Crater has a 2mm diameter and a 1/2mm
depth.
Clear upraised rim.
Second best crater of the
lot.
17.9g
Not oriented.
Crater is 3mm in diameter and ~1.5-2mm
deep.
47.4g
Oriented
Crater on the leading edge.
The crater is 2.5mm in diameter and 1.5mm deep.
Oriented, crater just off dead-center on the leading
edge.
Diameter = 4mm
Depth = 2mm
And here's a picture of all of the Sikhotes together;
the order from left to right, back row to front.
3, 2, 1,
6, 5, 4,
7
Best Regards,
Jason
