In other words since there is no sample collected from Mercury there is no way to compare O-isotopes with meteorites to conclude an origin from Mercury. I think a scientist might be willing to go out on a limb if the following conditions were met: 1) It was pure anorthosite or some other combination that could only be created on a planetary sized body and had a vastly different O-isotope measurement than the Moon, Mars or Earth. 2) It had measurable CRE exposure. 3) It had a young crystallization age. 4) It had evidence of higher levels of exposure to the solar wind because of its proximity to the sun. 5) It had no water-bearing or water-altered minerals such as pieces from Mars. 6) It had a high level of shock, possible maskelynation of feldspars. I have seen N3 and feel you need to wait for the all important O-isotopes due out within a couple of weeks. If the Isotopes are anomalous then a crystallization age must be determined and it has to meet several parameters before any statement of origin can be made. N3 strongly reminds me of Dhofar 378 on appearance alone. I think David Weirs site has an excellent picture of this. I hope it can be proven to be from Mercury. But with an estimated one in a hundred chance compared to Martian finds, based on current models, this would be an extremely difficult goal to achieve. You have come up with other fantastic stones so who knows something outrageous is bound to show up in your collection. When the O-isotopes measurements are realized I hope you inform the list of the results. It could prove to be pretty interesting. Anyway, congratulations on such an interesting find!
