Hi Marco: The short lived isotopes decayed 4.5 - 4.6 or so billion years ago, and only warmed the acreeted asteroid at that time. They are but a distant memory when the meteorite falls here on earth today.
As for hot rocks. I found Buzzard coulee specimens in the spring time 2009. The ones that were exposed to the sun, were nice and warm, almost hot, when we picked them up. : ) Murray Paulson On Wed, Nov 24, 2010 at 2:03 AM, Marco Langbroek <[email protected]> wrote: > Piper et al., > ...........................> > The same goes for reports of "very hot" meteorites. > > In more speculative moments, I have pondered a few times whether the decay > of very shortlived radioisotopes in meteorites could play a role in reports > of "glowing" and "hot" fresh-fallen meteorites as well.
