I classified this 44 gram meteorite and it is still in my possession; 9 grams of it is now in the IOM repository and the remaining mass of 35 grams will be shipped back to the owner. If you look at the classification in the MetBull you will see that I determined it to be a lunar fragmental breccia based on electron microprobe analyses. The find history was communicated to me by the owner which I reported verbatim in the write-up. This is normal practice. I was quite surprised to read on the internet today that someone is accusing Xinjiang meteorite hunters of transplanting NWAs to the Taklamakan Desert and implying that Pakepake 005 was also transplanted from NWA. The comment was on the MPOD website, but there was no tangible evidence provided by the accuser other than ??the physical and chemical weathering features were dissimilar from those of the meteorites recovered in the Xinjiang deserts by my team??. Obviously, such a public accusation should be backed up with quantitative data, however none was provided. I look forward to seeing such evidence if it exists or which tests were carried out to prove NWA transplantation. In the meantime, it is probably a good idea for everyone to take a deep breath and resist jumping to unsupported conclusions. Now for a few points of clarification. This meteorite was not sold to the owner by the finder as a lunar meteorite. It was initially identified as a likely HED and sold as such. I was the one who determined it to be lunar through my microprobe work. I have learned from the owner that hunters in Xinjiang are becoming more aware that the most valuable and rare meteorites are not necessarily magnetic like the lion?s share of what is normally found, namely EOCs. Therefore, they are now also on the lookout for achondrites. I believe a similar evolution took place in NWA many years ago and now we see mostly very rare meteorites coming from NWA because they have been high-graded by Saharan hunters and dealers ? the EOCs, unless massive, never see the meteorite market light of day. The owner also told me that the discoverers are Uyghur people from Xinjiang who might not easily obtain lunar meteorites from NWA to transplant and they typically want to remain anonymous. Does this mean that it is impossible for some of the Xinjiang meteorites to be transplanted? Of course not, this is always a possibility with ?found? meteorites ? anywhere in the world. On the other hand, am I surprised that a small lunar meteorite was found in China?s largest sandy desert? Not at all, especially given that there are now over 660 lunar meteorites in the MetBull, weighing many kilograms, most of which were found in the Sahara Desert. No one bats an eye when another ~10 kg lunar highlands breccia is found in the Sahara. I think the more interesting question is why are there not more lunars found elsewhere in the world like in the deserts of Antarctica, Atacama, North America, etc. And of course, why are there no lunar falls? ************************************* Carl B.
