New Paper on Trinitite in “Geology Today”

A new summary paper about trinitite was published in late 2010 in “Geology Today.” The paper is:

Eby, N., R. Hermes, N. Charnley, and J. A. Smoliga, 2010a, 
Trinitite—the atomic rock. vol. 26, no. 5, pp. 180–185.
http://onlinelibrary.wiley.com/doi/10.1111/j.1365-2451.2010.00767.x/abstract
http://onlinelibrary.wiley.com/doi/10.1111/gto.2010.26.issue-5/issuetoc

One conclusion is that much of the surface layer was not created by the melting of the ground surface as previously thought. Instead, they state that further work has shown that much of the trinitite had been entrained in the rising cloud of gasses and subsequently rained down onto the surface as molten droplets. A lot of this material still retains bead and dumbbell shapes
that were formed as the molten material was transported by the gas cloud. They note that a significant amount of these beads and dumbbells was blown downwind and accumulated over a fairly wide area. These beads and dumbells are now found commonly concentrated on the surface of anthills and sometimes called “anthill trinitite.”

Among many other things, they found that the red trinitite, which color results from the presence of copper, contains metallic chondrules that contain iron and lead. They conclude that the metallic chondrules “are melted bits of the first atomic bomb and the surrounding support structures—history encased in glass.”

Trinitite was "Who is Dr. LaPaz"

In the thread [meteorite-list] "Who is Dr. LaPaz" at
http://six.pairlist.net/pipermail/meteorite-list/2010-February/061407.html

Shawn Alan asked:

"Lastly, along with the meteorite specimens I also received
a trinitite fragment weighing at 1.79g that he had collected
from the Trinity project and was wondering if people on
the list knew much about this stuff."

Go look at;
