Re: [meteorite-list] CONCEPTION JUNCTION, MISSOURI PALLASITE - AD/test
Interesting composition! Might this hint the meteorite may be extra solar? a visitor from another star system? only time will tell!

Anyway, hope this helps answer some of the good questions that have been posted: The information I report here shows there is no main-group pallasite that is closely related to Conception Junction. Conception Junction is unique. If I compare Conception Junction with other main group pallasites (PMG) with Au contents within 10% of that in Conception Junction (i.e. in the range 2.0 to 2.5 mg/g Au), only Seymchan and PCA 91004 have Ir concentrations within a factor of two of that in Conception Junction. If I sort on Ir, I find that there is no other PMG among the 40 that I have studied that has a closely similar Ir value. The nearest are Pescora Escarpment 91004 (0.76 mg/g Ir), Seymchan (0.67 mg/g) and Barcis, a scarcely studied Russian PMG (0.32 mg/g Ir). The Co content of this sample is high (6.0 mg/g). If I sort my PMG data on the basis of Co, I find that there are three irons with higher Co, namely Krasnojarsk, Rawlinna 001 and one sample of Phillips County, and a couple more that are slightly lower, namely Springwater and Zaisho. The Ni content is also rather low, as is shown in the chart below comparing Conception Junction to PCA 91004, Seymchan, Barcis and Krasnojarsk. In summary, the composition of the metal in Conception Junction differs from all other known pallasites.
