*From Anders and Grevesse (1989). The values are relative to unit mass of C1 chondrite. tex2html_wrap_inline1516 for tex2html_wrap_inline1384 Al is based on the tex2html_wrap_inline1384 Al/ tex2html_wrap_inline1956 Al ratio of tex2html_wrap_inline1958 as was deduced from Ca-Al rich inclusions in carbonaceous chondrites (Clayton et al., 1988).

tex2html_wrap_inline1960 From Handbook of Physical Properties of Rocks (Robert, 1984) for tex2html_wrap_inline1508 K, tex2html_wrap_inline1510 Th, tex2html_wrap_inline1512 U, and tex2html_wrap_inline1514 U. For tex2html_wrap_inline1384 Al the data were taken from Table of Radioactive Isotopes (Brown et al., 1986).
