  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 to burst through to the surface. Most of the world's most productive diamond mines are located near large impact craters. The best example I can give is the numerous mines in South Africa that were developed near the crater ring structures of the Vredefort impact. The impact at Canyon Diablo didn't have the energy required to force eruption of the uppermost mantle through the crust. I wouldn't think that there is much potential to discover a diamond ore source related to the Meteor Crater in Arizona. Sincerely, ASTROBLEME
  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 from the Franconia track wreck site that has been searched by so many people over these years! The official find location is 34 degrees, 44 minutes, 48 seconds North and 114 degrees, 12 minutes, 36 seconds West. I've plotted these coordinates using Google Earth and the image is posted below.

  5. Erik: Thanks for your opinion.
  6. CONGRATULATIONS JIM! I am pleased to see that your effort has paid off. Johnny
  7. 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 specimen was retained by the University of Arizona. Here's a Google Earth image with the find coordinates plotted for the Meyers and Smaller specimens. The approved meteorite samples were collected more than 5 miles away from the Franconia Train Wreck site! ASTROBLEME
  8. 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 cannot be ruled out. A trajectory map is included so those that have telescopes can see if there is a change in the predicted path across the sky. Documentation of an orbit change would be a fantastic discovery although it will be difficult now since the apparent comet movement against the sky is quite slow. Please keep an eye out for any trajectory change as this would indicate an impact as the cause of brightening. Johnny
  9. 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 normal. This latest brightening is at least 1 million times the normal! My research into comet samples that I have recovered from impact craters reveals that they are not a “dirty ice ball” that many scientists have put forth. Water genesis by shock induced pressures in the amphiboles Cummingtonite and Grunerite yield samples that are primarily magnetite and quartz. These highly shocked samples show tiny fissures that allow for the large volumes of superheated water to escape. These particles can disperse widely in space and make for a spectacular visual display. The reaction for Grunerite is as follows; Fe7Si8O22(OH)2 + 7/6O2 →HYPERVELOCITY SHOCK INDUCED PRESSURE→ 7/3Fe3O4 + 8SiO2 + H2O (36) The reaction for Cummingtonite is as follows; (Fe0.6Mg0.4)7Si8O22(OH)2 + 7/6O2 →HYPERVELOCITY SHOCK INDUCED PRESSURE→ 7/3Fe3O4 + 8SiO2 + H2O (36) Sincerely, Johnny Tonko Copyright © 2006-2007 by Johnny F.

  10. 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 oxygen/acetylene torch and it will bubble and froth to release the volcanic gasses and water that is trapped in the glass. Hope this helps, Astrobleme
  11. 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
  12. Dear John B; Happy Hunting to you as well. ASTROBLEME
  13. 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 therefore it wasn't part of the mineral estate. I believe you are mistaken in your comment that mineral rights have nothing to do with meteorites. It would surprise me if Union Pacific or Newmont Gold would allow meteorites to be dug up out of their mineral estate without their consent. There are lots of lawyers that can help with understanding mineral rights and mining claims as well as the numerous case laws that set legal precedence that guide us. The only legal precedence set in the Old Woman matter is what was determined by the 9th Circuit Court of Appeals in 618 F.2d 618 9th Cir (1980). That case only confirmed that the Secretaries of the Interior, Agriculture and Army have broad discretionary power to dispose of objects of Antiquity found on federal land. There's nothing in that case about mining claims or mineral rights. The gold prospectors who found the 2nd largest US meteorite, David Friburg and Mike Jendruczak, weren't parties in that case yet many people seem to think that their claims had been heard. I suppose the best historical example of how meteorites and mining claims interact would be the Barringer family's ownership of Meteor Crater in Arizona. Sincerely, ASTROBLEME
  14. 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
  15. 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 is only my opinion. You should always seek your own legal advice. Sincerely, Astrobleme
