http://www.theodoregray.com/PeriodicTable/Elements/077/index.html#samplex1 The picture of the metallic substance I have several of . . . they are very easy to spot at the find site because they are so bright and shiny. I'm not second guessing myself Dave, I am second guessing the experts. The find is what it is. It must be explained. I know of no other impact that resulted in a K/T layer, so I have to stay with Chicxulub. Maybe the thing came in so shallow it bounced. It was, after all, over 10km wide. The volcanic issue is one I'm also quite certain of. The lava bombs here were sent so high that every piece shows evidence of ablation, thumbprinting and flow markings. Normal volcanic processes can produce small numbers of such objects but what exists out here is ridiculous. Dave, thanks for the naysay. If you want one of these nuggets, I'd be happy to send you one. Let me know. A million to one doesn't happen every day!

Wyoming has three that I know of that aren't even on the poster. You more than likely have something related to a currently known impact site or one that is yet to be catalogued yet, rather than a Chixulub ejecta field. Your writings below tend to point out to me that you find it can't be so yet you second guess as I do myself when I am so involved in a project. I would go with some of the impact professionals but...many other things could be the percentage shot.

Thank you Dave. You know it never occurred to me that I would find iridium nuggets, but it seems that's exactly what these pieces are. I just located a photo from the Harvard Museum of Natural History of a natural iridium nugget and I am completely convinced that's what I have here. Now I'm confused on these impact pieces. Iridium's melt/flow temperature is around 3500 degrees F conditions that could only have been present in the vicinity of the impact. That makes these iridium splattered hunks of brecciated calcerous limestone part of the original bottom of the Gulf of Mexico. The location I am finding these pieces is more than 1500 nautical miles from Chicxulub. The current science of impact structures has embraced a general formula for impact ejecta distribution maintains that 95% of ejecta should make landfall within 5 crater radii of the center of the impact. I would place my location at least 10 radii from Chicxulub. I think the angle of attack of the Chicxulub impactor has a lot to do with this anomal
y. The object arrived at a 20-30 degree AoA travelling from SE to NW. Careful study of the radar images of the Chicxulub crater structure shows perhaps a 20 degree segment of the NW crater isn't there. Maybe that's because it was violently propelled toward this place? <dfreeman_at_fascination.com> wrote:You need to get some of your K/T boundary clay suspects off to a lab for

there. We have a half inch thick layer up by Castle Gardens in central
Wyoming. Colorado has a thicker layer than that in a few spots in
Southern Colorado. Heck, it was first discovered in Italy.
Best of luck.
