Hi all list members, I have not posted to the list in quite a while. I did not like some Of the posts I had made, especially regarding other list members, so I withdraw for about 18 months to self assess before posting again. My email application totally crashed recently and it has taken Weeks to retrieve ANY of my old address book. When I did, it was From 2014! So, anyone and everyone who has changed their email, Phone and/or address since sometime in 2014, PLEASE email me With all information, putting “UPDATE” in the subject box - Thank you. In addition, the same happened to my sales lists, of which, in Addition, I lost ALL of list #5. So, if you would like to receive my VERY OCCASIONAL (i.e. 2 to 5 times a year) ads, please email me with “METOEORITE ADS” In the subject box and I will add you to my list. Everyone knows my Ads ALWAYS contain some killer pieces/prices that result in even Other dealers contacting me immediately. IF YOU WERE ALREADY ON MY LIST please include the following: 1) Your old email address 2) the List # you were on (some were on more than one list - inc. all) 3) Your current email address I will make sure you are only on one list and your email is current. NONE of my emails are ever sold, traded or exchanged to other Parties - ever. Thanks to all list members for their patience with me. Hope to see y’all in TUCSON at ET’s on Fri, Feb 3 and/or Blaine’s Sat, Feb 4 where I will sign Aspects of Meteorite Orientation (Which will be on Show Special 1/2 price) Very best wishes to all, Michael Blood __ Visit our Facebook page https://www.facebook.com/meteoritecentral and the Archives at http://www.meteorite-list-archives.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com https://pairlist3.pair.net/mailman/listinfo/meteorite-list
[meteorite-list] Comment re A Question
I am so sorry that I ever asked my question. I am still learning about these meteorites and all the terminology that goes with the subject. I shall crawl back into my little hole and never again even peek at the list again. The other question re the survivability of an earth bug in a Mars environment was just ignored.. Go figure All I wanted to do was learn something. Next there will be a war abrewing over this inane thread.

[meteorite-list] Comment on Fireston rebuttal
Hi all - The review team did a good job, but... We also have the peoples' accounts to deal with. It seems to me that there was no reason for them to create such extraordinary parts of their histories, unless some extraordinary and memorable event actually happened. I think we have a rough idea of the normal flux of micro-meteorites, so the black mat data will have to be examined in terms of that. I agree with them that the Carolina Bays are probably not part of the holocene start impact, but it is possible that they came from an impact megatsunami ca. 8,350 BCE. Another USGS team is working on the coastal Atlantic sequence. The rebuttal team also graciously ignored the peppered mammoth tusks, but then these are clearly from a separate iron impact event. good hunting, E.P.

[meteorite-list] Comment on M. Blood's Met. Market Trends 05-07
Hello Michael, The Meteorite Collectors Price Guide, by David Weir, to which you refer in your recent Meteorite Times article (just after Kevin's contribution), was compiled by me for about 5 years, up until January 2001, the beginning of the new millennium, when I quit revising it. At that time I allowed Doug (Meteorite Express) to work on it at his pleasure and I removed its link from my website. He continued to update it (mostly the date) in a very minor way. You're correct, it's quite obsolete. At the time I quit revising it, the NWA boom had led to widely varying, abnormal market conditions, almost impossible to adequately monitor, and the price range listed had grown so wide that no meaningful information could be derived from it any longer. My interest in recording prices was for my collection goals just as it was for Kevin and probably Thomas and others, but this was at a time when the number of dealers could be counted on both hands and ANY meteorite offered for sale was a great occasion. A large percentage of meteorite types were unavailable or unknown. Conversely, at the present time every collector is a dealer (primary, secondary, tertiary, etc.), ebay lists dozens of pages of meteorites of every variety for auction, Google searches are magical, and lunar and martian stones, along with samples from the very rarest of groups, are relatively easy to acquire. My Availability Code -- 1) Good Luck!, 2) Here, There, 3) Everywhere -- would now be all 2's and 3's. I doubt if any price guide is able to provide a realistic and timely picture of the current market price ranges; in fact, I was often told this about my own price guide, which was modeled after Philip Bagnall's efforts in his informative book, by some dealers (by yourself too as I recall, and I even included a median price). I felt my efforts were still worthwhile at the time, and it provided me with the information I needed to have -- the difference between a good price and a bad price -- at my fingertips.

[meteorite-list] Comment on zigzagging
Howdy, list I've been very busy this past week and someone may have already made this comment - apologies if so. I wanted to point out that zig-zagging may simply be an artifact of apparent viewing angle. I've attached a crude doodle to this email; I don't know if the listserv allows such things... Picture this - a meteorite tumbling through the atmosphere is tumbling, and traces a corkscrewing path through the sky. Hold up a corkscrew - if you look at it point-on it looks like a circle and if you look at it side-on it looks like a sine wave. If you turn it about 45 degrees or so it is sharply distorted in the vertical - it looks like a zig-zag pattern. It also looks very much like that picture of Pasamonte's ingress that was passed around. I'm not convinced that meteorites can zig zag sharply across the sky - I would assume that violent maneuvers would tend to break them up. Zig-zagging is likely just an artifact of observation. I also take back my previous notion that zig-zagging likely indicates a piece of space junk - apparently anything can appear to zigzag if you look at it from the right angle. Again; my apologies if everyone has gone over this already - I had to trash a lot of messages this week without reading them. Cheers, MDF -- Marc D.
