During preparation of the CD-ROM the data has also been "cleaned" by replacing all 0 (below detection values) with a value 2/3rds the reported detection limits (rounded to an integer) i.e.

Element Detection Limit (ppm) Substitute Value
Cu 1 1
Pb 9 6
Zn 3 2
Co 3 2
Ni 2 1
Mn 26 18
Li 1 1
Sn 4 3
W 4 3
Ta 5 3
Ba 54 36
As 10 7
