Elements higher than Fe (iron) were produced by spallation. Therfore in the beginning (4,6 Byrs ago) the cloud from which our solar sysem was built up was homogenous, comtaining all elements of the PS as we know it tuday. Even the elements Pu+Np, Tc, Pm were abundant. Lot of radioactive isotopes of the elements were abundant, like 26Al. Depending of their short half-life the are today absent. But the stable daughter elemental isotopes are abundant. In CAIs of meteorites is an excess of 26Mg. Thats it.

Dez. 2008, 22:35 Thema: [meteorite-list] Meteorites, Elements and The Periodic Table I understand that many mineral constituents of meteorites are regarded as still unrepresented among native terrestrial products. Are there any elements that are unique to meteorites? _________________________________________________________________ Send e-mail faster without improving your typing skills. http://windowslive.com/Explore/hotmail?ocid=TXT_TAGLM_WL_hotmail_acq_speed_122008 ______________________________________________ http://www.meteoritecentral.com Meteorite-list mailing list Meteorite-list at meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list ________________________________________________________________________ AOL eMail auf Ihrem Hand y!
