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 ?g/g; Ge ~80 ?g/g; As 29 ?g/g; Ir 0.50 ?g/g; Au 2.39 ?g/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 ?g/g and Barcis at 0.32 ?g/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.
Carl
