Estimated using data from the 10 samples (2, 92cm increments) of profile 3, stratum 1, A site.
The x + S.E. atom perc 5 t 2354) for these samples
Atom percent of natural
U is 0.720.
More data is needed to confirm these estimates of natural 3 U
was 0.720 + 0.0064.
ttt Preliminary
estimates.
About 50% of results are reported.
