Just noticed something in the second photo of breccia- if you use the larger white- cream- green- speckled rock inclusion that looks vaguely like the continent of Africa, ( on its side in second photo middle lower left in slab) there seems to be a line where the pieces are lined up from the immediate right side of "Africa" and the pieces seem to form on either side of that for an invisible vertical line the length of the slab. Not a fault or a crack, but don't they appear for some reason to have lined up?

I am depressed and suicidal. The geologist mentioned pyrite, and I wanted nickel. Nickel is meteorological, pyrite is earthy. Bursted my bubble badly. Darn. it sure has the color of pyrite. Don't feel bad. If you would like some nickel just let me know. I have many pounds of it  |

I'm not ready to discount the chance that some of it is nickel. Under the stereo scope I could see at least two different colors of 'pyrite' near each other on more than one of the slabs. Honestly I think Wayne was using the same approach we do in medicine. Always expect the most common and you don't start considering the rare until you disprove the common. |

Just the fact that the relatively small area defined as an impact site supplies most of the world's nickel speaks volumes. How much nickel is in a 9 kilometer meteor ? Testing the metal components should be one of the easier tests. All interesting. Will hold off on the drastic measures. |

Nickel in hydrochloride acid makes green nickel chloride. Carcinogenic so be careful.

Very interesting rocks to say the least.................You should slab one of every rock that is there,put them om display,after you get proper ID's for them............. would be great, sadly most specimens are cut and ground up in the analysis, still it is worth it to get the information. I am sure I will be able to find more like these (well maybe not too many like that polka dotted one!) I wonder if anybody has ever made a wall just with interesting slabs... I could do that but they'd have to be removable. Inevitably I want to turn them over and examine both sides... I know, a Lucite wall imbedded with slabs... rock hound fantasy room come true. OK, maybe I need more coffee this morning. no, I'm sure I need more coffee. |

Occam's Razor perfectly defined. When kidlet had her appendix out as soon as I left the room they asked if she could be pregnant (no) so then appendicitis it is!! Ann are you a physician? |

Master Shotgunner, I thought of you and Occam's Razor immediately when Ann mentioned that... |

No, I'm a clinical laboratory scientist/medical technologist. I currently supervise Point of Care testing and Special Chemistry for a local hospital. I did teach a laboratory practicum for a family practice residency program for many years. It was my favorite position I've ever had with the hospital. It allowed me to work closely with patients and doctors alike. Not to mention all the free lunch and lectures I could participate in every day. I learned more about medicine during those years than I did during my own internship. |

OK, maybe I need more coffee this morning. no, I'm sure I need more coffee. When I left the red and green specimen with Wayne I told him that I wanted at least half of it back if he could. I already planned on sending you some back if you didn't have an identical one sitting at home already. You will just need to tell me if you want a polished slab or a cab back (maybe if I get enough back I may be able to do both!). Wayne didn't think that he would need to destroy too much of any of the pieces for analysis. Most everything he felt he could analyze using thin sections. |

That would be great! an end cut would be plenty, no need to finish it... I would just like to have a little piece to use as reference, to help me understand it. I really would have been ready to see it all get ground up to tell us what it is/was. curiosity will probably be my undoing some day. I keep some cut rocks to help remind me what to look for, others to remind me what NOT to look for LOL. So often the insides look very different than the glacier/lake worn outsides. Thank you Ann!

Haven't been posting responses to your impactite thread, but just wanted to let you know I find it all fascinating!! Especially like all the help everyone else has been able to provide.

This one looks impactified, has a few metal/pyrite bits, looks like it recrystalized around the center breccia. Lots going on.   |

Because you are working for the aliens Jean, and do not want to expose their secrets. It is a known fact that you live in their breeding grounds. |

Jean, an absolute blessing, so many people here have contributed so much to my education, reached out to help in so many ways. The people on this board are a huge and extremely valuable resource, and I count my blessings every day that you all are here! Thank you all so much!

1dave, it brings solace to my simple mind when these impactites are analyzed. I find they display evidence of cataclysm when found in obvious impact sites, time and time again. Same as the relatively undisturbed coral beds. Many reef sections still in tact. Left almost undisturbed. Why am I so closed minded to estimates of time, and dependent on physical evidence ? paranoia I suppose
