  1. Pretty sure that's a hot rock with magnetite, which has a metallic luster when freshly cut; the GB meteorites don’t have large masses of nickel-iron...just small flakes like your smaller specimen.
  2. The closeup of the window into your rock is definitely showing metal flakes typical of the GB meteorites...great photo. Lots of the fragments have been broken and the fusion crust stripped away by mechanical weathering, leaving no obvious exterior characteristics of meteorites, so they can be difficult to recognize until the interior is exposed, showing the telltale nickel-iron flakes.
  3. Hope you get to shoot some footage of a decent lump at depth with your 17”, Bill. Looking forward to patch hunting with one during next fall and winter’s desert prospecting season, if they’re available by then. Been there, Mike...nothing worse than having gold fever and cabin fever at the same time.
  4. I haven't been out in the hills too often lately, what with working lots of overtime at my summer job, road and area closures due to forest fires and such; in fact, I can still count on one hand the number of outings with the new GPX 6000, and only a few hours each time at that. Pictured above is what I have found so far, just going over spots I have thoroughly gridded with previous ML PIs, the GPZ 7000, Nox, GM 1000, and couldn't find any more targets. 5.2 grams total. It's what I have come to expect from Minelab over the years: new technology + old patch = more gold.
  5. Got my third Nevada cold find today; story here: https://www.detectorprospector.com/forums/topic/15876-new-nevada-cold-find/
  6. Joemonk, I've had the best experience with Alan Rubin's team at UCLA; very quick turnaround: https://meteorites.ucla.edu/research/ Best of luck to you.
  7. The interior is way too light in color for typical basalt, although leucobasalt can be very light in color. Achondrite all the way...IF it is indeed a meteorite...expert analysis is required for that determination.
  8. I'm by no means an expert on the chemical composition of meteorites, but from what I've read about the subject in O. Richard Norton's “Field Guide to Meteors and Meteorites”, Appendix 1, the lack of calcium, magnesium, potassium and sodium in the university lab analysis does not bode well for a stony meteorite; unless, of course, the analysis did not test for these elements. As for an iron meteorite, the outer surface and cut surface of your specimens do not resemble any irons that I have handled or seen photos of, and a recent fall would be in pristine condition. If you suspect your rocks to be iron meteorites, I would suggest doing an acid etch to see if it reveals a Widmanstätten pattern: https://en.m.wikipedia.org/wiki/Widmanstätten_pattern
  9. It's better than a reality tv show, Mitchel...you can’t make this stuff up! 🤣
  10. The famous Meteorite Men are together again! A new short film series starring Steve Arnold and produced by Geoffrey Notkin. Meet expert meteorite hunter Steve Arnold, one of the stars of TV's multi-award-winning Discovery Science series "Meteorite Men." In this exclusive YouTube series, Steve teaches you how to find fallen space rocks, and what equipment you will need out there in the field. Learn more by visiting Steve's official website: https://www.fireballsteve.com
  11. I hope you catch that big space fish; good luck!
  12. Must have been small filings from the file adhering to the surface; you may want to clean the surface and then look at it again under magnification, as granite will never contain metal flakes.
  13. Contact Information Daffy, you can email some photos and a link to this forum thread to: Alan E. Rubin aerubin@ucla.edu Institute of Geophysics and Planetary Physics University of California Los Angeles, CA 90095-1567 Telephone 310-825-3202 FAX 310-206-3051 Here's a link to his web page: http://cosmochemists.igpp.ucla.edu/Rubin.html Good luck, and please keep us updated here.
  14. While that is generally true, there are always exceptions; for example, this 98% fusion crusted, 120 gram Tissint shergottite achondrite individual, which shows a remarkably rough and uneven surface:
