[meteorite-list] Conception Junction Specimen / Monograph
Hello List, I came home today to find my specimen of Conception Junction and the Monograph in my mail box. Wow! A beautifully prepared Pallasite and of course a well thought and well put together description of the meteorite's history. Once again, congratulation and job well done! Thanks guys.

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.

[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)
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.

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.

Information about the Conception Junction pallasite, available specimens, and its monograph (authored by Dave with contributions from Dr. Wasson), can be found here: www.conceptionjunctionpallasite.com Limited material will be available to the private collector community, as we are holding specimens in reserve for institutional placement.

[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.

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.

Hello Dave, Karl A., and List, Just a short note to avoid misunderstandings! Of course, I never doubted the landowner's credibility, nor yours, and, Dr. John Wasson's credibility and authority are quite certainly beyond any doubt! 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.
