Carl, this may help:
Conversions
1% = 10,000ppm = 10,000ug/g = 10mg/g
10% = 100,000ppm = 100,000ug/g = 100mg/g
100% = 1,000,000ppm = 1,000,000ug/g = 1000mg/g

Laurence,
Sorry if this is a stupid question but none of the other pallasites in the
bulletin show their data this same way.
looking at this data . What does it mean when it says;
mg/g etc...
Is this milligrams divided by grams?
What would the percentage be put in a way that it can be compared with the
way others are reported?
Geochemistry: Compositional data: Co 6.0 mg/g; Ni 79 mg/g; Ga 24 μg/g; Ge
~80 μg/g; As 29 μg/g; Ir 0.50 μg/g; Au 2.39 μg/g. Data are the mean of
duplicate determinations. The composition of the metal differs in detail
from other pallasites. For example, the Ir concentration is 0.50 ug/g,
with the nearest relative Seymchan at 0.67 μg/g and Barcis at 0.32 μg/g.
Classification: On element-Au diagrams, Conception Junction plots
distinctly lower than most PMG on Ni and Cu and above most PMG on Co, Ga,
As, and Ir diagrams; it is therefore classified as PMG-anomalous (PMG-an).
Its Ni and Cu contents are the lowest known for PMG. Its nearest PMG-an
neighbor on most diagrams is Krasnojarsk. The low Ni and high Co could
reflect unrepresentative sampling of kamacite and taenite but these are
the means of two replicates.
Thank you.
