Re: [meteorite-list] Changes In 14C and Impacts
Hi Sterling, Paul, List - Re: Date of Kitscoty structure Since there have been many ice ages, it seems to me that if the Kitscoty structure was more ancient than the most recent ice age, it would have been scoured away. Hence the timing of its formation would seem to agree with the documented water releases. Please remember that this may have been the first impact of a piece of Comet Giacobinni-Zimmer. The 10,850 BCE impacts were likely to have been the second impacts of pieces of this comet. But refining these dates and aligning them with cometary dynamic orbital models is well beyond my current computational abilities. Re: Changes in 14C and impact If I remember correctly, it was a leading Chinese nuclear physicist (unidentified by name in the paper) who first discussed the production of 14C in comets. Comet composition may be one factor in the 14 C loading. But if we look at the InCal charts, we can see a dramatic change in 14C associated with the Meteor Crater impact, which we know was produced by he impact of an iron asteroid. Hence my hypothesis that in hyper-velocity impacts, some of the photons reach gamma ray energy levels and release neutrons. If this is so, then the area around Meteor Crater may show or may not show some unusual isotopes, depending on their half-lives. good hunting, everyone E.P.

Dear Ed: On June 28, 2015, in “Changes In 14C and Impacts,” you wrote: I am looking forward to your comments on the Kiscoty structure. At this time, I lack any comments about the Kiscoty structure. The problem is that the only material that I have been able to find about is a newspaper article that lacks any coordinates and has only a medium to small scale map with terrible resolution and lacking any mark as to where this feature is in the map. Given, the scale and resolution of the the article’s map, it is impossible discern what in this map is the “Kiscoty structure” and exactly where it is located. I would need a specific location, preferably a latitude and longitude, of some sort for its center and what its diameter or radius is to be able to comment on the Kiscoty structure.
