I only judged from the visual appearance of the samples, and we all know that even though pictures sometimes speak a thousand words, they can also sometimes be quite "taciturn".

[meteorite-list] Conception Junction Pallasite
Dave is not able to post at the moment, and rather than rewriting this I am forwarding it for him. Obviously I had concerns about specimen transport prior to acquiring the meteorite in Conception Junction -- not because the landowner wasn't credible, but rather because it was possible a the stone was transported by a native American, perhaps centuries ago. It's hard in photographs to notice this at first, but the average crystal diameter of Brenham specimens we used for comparison was about 7.5 millimeters, whereas Conception Junction averages only about 4.5 millimeters. It's painfully obvious in a direct comparison that the two are quite different based on physical characteristics alone (including several factors, not just crystal size). Then of course there are the findings of UCLA's Dr. John Wasson, the world's authority on iron and pallasitic meteorites, which are detailed in the monograph through his contribution to same. To summarize, he wrote, "The information I report here shows there is no main group pallasite that is closely related to Conception Junction. Conception Junction is unique." __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
Re: [meteorite-list] Conception Junction
Bernd, Michael G., & All, I see that Robert got a draft of this note out earlier, but I've added a little more detail here as well. Michael M. hit on part of this in his post, but you raised a reasonable question that we're happy to address. Obviously we had concerns about specimen transport prior to acquiring the meteorite in Conception Junction -- not because the landowner wasn't credible, but rather because it was possible a the stone was transported by a native American, perhaps centuries ago. It's hard in photographs to notice this at first due to a lack of perspective (even with a scale cube), but the average crystal diameter of Brenham specimens we used for comparison was about 7.5 millimeters, whereas Conception Junction crystals average only about 4.5 millimeters -- among the smallest of all known pallasites. It's painfully obvious in a direct comparison that the two are quite different based on physical characteristics alone (for several reasons, not just crystal size, including crystal aesthetics and the relatively unique exterior). Then of course there are the findings of UCLA's Dr. John Wasson, the world's authority on iron and pallasitic meteorites, which are detailed in the monograph through his contribution to same. To summarize, he wrote (as Michael M. noted), "The information I report here shows there is no main group pallasite that is closely related to Conception Junction. Conception Junction is unique." He had several other points to make as well, including, "In summary, the composition of the metal in Conception Junction differs from all other known pallasites."

[meteorite-list] Conception Junction approved (question)
Carl inquired: "none of the other pallasites in the bulletin show their data this same way. What does it mean when it says: mg/g etc." This is milligrams per gram. and: "What would the percentage be put in a way that it can be compared with the way others are reported?" Well, like this: Ni = 7.9%, Ga = 24 ppm; Ge ~80 ppm; Ir = 0.50 ppm So, it does have a low Ni content (comparable to that of Marjalahti: 7.81% Ni), the iridium value, on the other hand, is remarkably high. Brenham, for example, has an iridium content of only 0.041 ppm. In other words, C.J. has an iridium content 10 times higher than Brenham.

Re: [meteorite-list] Conception Junction approved (question)
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.

Re: [meteorite-list] Conception Junction approved (question)
Hi Carl, Yes, mg/g is milligrams per gram and µg/g is micrograms per gram. thus, 6.0 mg/g is 0.6% or 6 ppt (parts per thousand, the analog of percent but based on one-thousandths) and, 24 μg/g is 0.0024% or 24 ppm (parts per million, the analog of percent but based on one million) and If none of the other Pallasites show data that way it is probably because they were published before measurements of trace metals was seen as an important classification tool (at least, in the opinion of Wasson et al). Wasson published a huge paper/review with many tables on the subject comparing many irons and arguing that trace metals are a good classification tool. I am still amazed he has had as good results as he presents, since meteorites are natural materials and variations among traces doesn't seem unlikely, though I am sure others will view the mixing as more uniform (but - if everything was so uniform, for example why do we have more olivines in some slices, or areas of many inclusions, etc, ok ... seeding for crystals an imperfections is a different concept but still ... enough of my monologue - I( am sure he has run many duplicate runs using different sampled sections of material from the same meteorites and found that on balance perhaps even if one metal is off, they can be relatively independent variables - at least some of the metal concwentrations, relative to each other and are useful in separation. Not an easy sell or an easy job, I would have gone bananas with such a project if I had such a monumental task to deal with in a lab. You really got to give him credit. But I still bet there are some nuances in this classification system that will need to be worked out due to the base assumptions of mixing. They will probably be attacked by ratios and appropriately selecting metal element pairs or subgroups. Oh wait, of the 20 US pallasites, the one published to Concepcion Junction was Milton, also of Missouri, in 2000: http://www.lpi.usra.edu/meteor/metbull.php?code=16691 you will notice it is the latest one - same format: Milton Found 2000 October Pallasite A single mass of 2040 g was found in a bean field by Ben Rogers and Gary Wennihan. Initial identification was made by C. Rohs and J. Reese at Northwest Missouri State University. Classification and mineralogy (R. Jones, UNM; J. Wasson, UCLA): Small, angular olivines (73 vol%), mean Fa17.2; molar Fe/Mn = 123; metal composition, Ni = 151 mg/g, Co, 9.6 mg/g, Ga, 15.3 µg/g; As, 10.1 µg/g; Ir, 50.4 µg/g, Au, 1.16 µg/g.

Re: [meteorite-list] CONCEPTION JUNCTION, MISSOURI PALLASITE
Martin: Milton is unique in large part because of it's olivine composition. I've taken Fig. 2 from the LPSC2003 abstract you mention below and added a point (red) for Conception Junction (our analyses). http://meteorites.wustl.edu/Conception_Junction_&_Milton.jpg Milton is off by itself whereas Conception Junction plots near the Main Group pallasites.

Information about North America's 20th pallasite can be found here: www.conceptionjunctionpallasite.com I was unable to post earlier due to incorrect email settings and I am reposting this link as a test.

Wasson's statement that: …there is no main-group pallasite that is closely related to Conception Junction. Conception Junction is unique." leaves open the question at to what is the classification? Is it ungrouped, or perhaps, main group anomalous? I would be most interested to know the major and trace element analysis so I could form my own opinion.

Re: [meteorite-list] CONCEPTION JUNCTION, MISSOURI PALLASITE - AD/test
Michael & All, Dr. Wasson submitted his classification of the Conception Junction pallasite (PMG) to the Nomenclature Committee last month, and presumably it will be posted to the Meteorite Bulletin before long. Since much of this information is not publicly available at the moment, please find below an excerpt from Dr. Wasson's contribution to the monograph. He also complied an interesting chart for comparative analysis, but I'm not sure how to post that information with plain text. 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.
