I think it is fairly clear that the glass in chondrites, which forms
in chondrules because of their rapid cooling from a partially molten
state, is stable on the time-scale of the age of the solar
system. In the most primitive chondrites, the ones unaffected by
reheating or alteration on
Hi Jeff,
Congratulations on the cover story in Science on formation conditions of
chondrules. Your color photograph of a Semarkona cross section is
fabulous.
Cheers,

Hi Jeff and Jim, Wow, tell us more about the article in Science. Could it
be ordered as a single copy at this point? Tom

Have any studies been done on decay
Have any studies been done on decay of glasses in meteorites into crystaline
configurations? Is there a mesurable rate, or does it not happen?
This story brought that to mind-- if impact-generated glasses in meteorites HAVE
NOT decayed into crystaline material in 4 billion years, it's fairly
Hi, Several years ago I ran onto an unusual chondrule in JaH 055 that looks
like glass but it is forming in crystals. I have had various explanations
presented to me and all involved Glass This might be On topic?
If any one is up to taking a look and sharing their observations, I would
