Hello again!
I'm the one who started this discussion and I think I might not have been specific enough
in asking my question. I do realise that there are many parent-dauther isotopes that can
be used in dating meteorites. I'm also aware that the method of dating would be chosen
according to the composition of the meteorite as well as the age that is to be inffered
( and ofcourse there are other things to be considered). What I ment to ask is:
Why is this isotope pair (129I/129Xe) applicable to MOST meteorites?
Joel Schiff mentions that 129Xe is found in chondrules. Would it be correct to determine
that this method is applicable to most meterorites because 86% of stony meteorites
(which themselfes represent 95% of all meteorites) are chondrites?
Thank guys!
Best regards,
