  1. TOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOT....................................TOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOT! Looks like this could be the end of the "Franconia Iron" train wreck specimen collecting effort... :whoope: ASTROBLEME
  2. has not set their status

  3. Hi Everyone: I have been working for several years on diamond ore associations with meteorite impacts. While there are examples of micro diamonds found inside of meteorites themselves, commercial ores contain diamonds from sources that were formed deep within the Earth. In some cases, an impact cratering event can bring these deep diamonds to the surface. Basically, the large impacts that create large (10 mile+) diameter craters, cause a brief overpressure on the crust and subsequently opens numerous deep fissures that allow for the pressurized kimberlite or related diamond bearing rocks t
  4. Hello Everyone: Years have gone by and now, after all that time, a location for an ungrouped iron meteorite from the general area has been officially revealed. On May 18 of 2004, Pete Meyers recovered a mass of 8.60 grams. More than a year later, Jim Smaller recovered a 43.7 gram mass. Both specimens were identified as meteorites by Schrader, Lauretta, Domanik and Hill of the University of Arizona. The total known weight of 52.3 grams was given the name Sacramento Wash 005 by the Meteoritical Society as of January 14, 2008. These meteorite fragments were recovered more than 5 miles away
  5. CONGRATULATIONS JIM! I am pleased to see that your effort has paid off. Johnny
  6. CONGRATULATIONS to Pete Meyers and Jim Smaller for properly documenting an ungrouped iron meteorite from the Franconia area. Their find made on May 18th, 2004 was approved on the 14th of January, 2008. It took almost 4 years to classify their discovery and I am glad to finally see their success. While many more specimens are likely to be paired with the Sacramento Wash 005, caution must be used when claiming that classification. I have little doubt that some "FRANCONIA IRON" will be marketed as SaW 005. The total mass of SaW 005 is 52.3 grams from which a total of 11.35 grams of type s
  7. Jason: Excellent photo and it rivals many of those I've seen put up by the "pros" recently. That image is a trophy to be proud of! The particle cloud is still expanding at a rapid rate and now exceeds the size of the sun. The discovery 115 years ago was made after it brightened just 5 months after perihelion. It is interesting to note that it is again 5 months after it passed close to the sun and I am thinking there was a collision that caused the particle discharge. There are a lot of asteroids in the belt that the comet must traverse between Mars and Jupiter and a high speed impact
  8. Dear Jason and others with telescopes: Is it possible to determine, at his early date, if the comet has altered the well established historical orbit? My thinking is that there was a collision with another object that released the material that we are now seeing. Hyper-velocity impact would move the main comet body off course. All of Comet 17P/Holmes historical orbit lies within the Mars and Jupiter orbits with a period of 6.9 years. It is not a "deep space traveler" as many scientists speculate all comets must be. The object was discovered over a century ago when it grew brighter than n
  9. Hi Kel: The photos that show the thinner edges seem to have a gray coloration. There also seems to be quite a bit of inclusions that might be gas bubbles. If the specimen was a true tektite, there shouldn't be any gas bubbles and the thin edges should look brownish rather than gray. Perhaps you might try and break off a very small chip and subject it to a torch flame test. Tektite will glow brightly, even to the point that you cannot look at it without hurting your eyes, all without bubbling, frothing or melting. Volcanic glasses (like obsidian) will quickly melt in the flame of an oxyge
  10. Hi Dave: I'd encourage you to purchase several different types of meteorite specimens and practice "finding them" with your detector. If you are heading to a known strewn field like Gold Basin, put representative samples of the meteorite into plastic bags. Then bury the bagged samples in the soils common to the search area at different depths before you start. You can then fine turn your detector over the buried targets and that will certainly give you an advantage. Best of luck and I hope you enjoy yourself. Johnny
  11. Hi John B: I've been quietly digging 'rites so I haven't had time to post much lately. Meteorite impact craters are the most common geological formation in the universe. You can see them on our Moon, all the other planets and even impact craters on small asteroids and comets. All the minerals found on Earth have accumulated from meteor impacts over the eons. We just don't see many craters on Earth due to erosion and many meteors slow too much through our atmosphere to make an impact. The Old Woman meteorite was lying on top of a bunch of boulders. It did not penetrate into the Earth so
  12. Jason: I'm thrilled to see you enjoying yourself now that you are back home. Please accept my gratitude for all that you've done for our country. I hope someday that we will cross paths. I promise not to be a jackass! Sincerely, Johnny
  13. In general; A meteorite that is "on the ground" isn't part of the mineral estate and it would belong to the surface land owner. In the case of Federal lands, a meteorite located on top of the ground belongs to the Federal Government and the American Antiquities Act of 1906 (16USC431-433) Preservation Laws would apply. When a meterotite or fragment of a meteorite is located "in the ground", for instance buried due to an impact cratering event, then it is considered part of the mineral estate. The mineral rights holder is the rightful owner of the buried meteorite specimens. Of course this
