[meteorite-list] Meteorites, Elements and The Periodic Table

[m42protosun at aol.com]

Hi list and Bill,
all matter of our solar system is produced from stars of the 1st and 
2nd generation. 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.
Uwe

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?
