Here is a US American classic stone from my collection, pics of which I would like to share with you. The view of the cut surface of this 75.42 g stone is far from being perfect, as there are actually many shiny NiFe metal flakes on it, when put in good light conditions, but the actual weather here doesn't allow for a better pic with my limited camera equipment. And while I will be away for a couple of days now, I promised to show it in short time, so here we go. This crusted end piece has been acquired from a well-known organizer of a famous European meteorite show in the year 2000, and was formerly, as the sale label explains, in the collection of the Houston Natural Sciences museum. I was at the Holbrook site for two times many years ago, after visiting Meteor Crater nearby, last time in the early Nineties, but did not find anything but small crumbs near the railway tracks which somehow resemble that famous fall of 1912, first mentioned as an L6, but later on revised and suggested to be an L/LL6 stone. |

Spectacular Holbrook, one of my favorite strewn fields to hunt. |

As Ben and the many other successful hunters know, it is always such a treat to find even a small Holbrook. So distinctive when you pick up the loupe and see the fine cracks in the crust! |

My apologies, Alex. Your excellent description is now in its proper home :) |

I am hyperaware of it, Alex, and it's even egg-shaped. Say good by to Holkbrook, Daddy : - ( |

maybe LL5, with scattered metal? :) |

You are right, John. Though it still shows defined chondrules, and also lots of shiny NiFe flakes, which can*t be seen in pic #3, unfortunately, because of quite bad light conditions when I took the pic. |

Love the shape, and photo 3 especially. This view gives us an obvious "Amphoterite" look to me. This piece looks like a LL. |

[Thank you my dear collector friend Matthias! Oh, before I forget: you can also see a Black Hole in these pics. That*s in my garden, sitting in the middle of an old galaxy table and always trying to accrete me...] |

Fabolous piece of this historic fall (guess we can call it historic: 107 years on this planet).
(We ourselves get historic step by step, don't we?)
I like endcuts like this one - they reveal all, in this case: fresh black fusion crust with some contraction cracking, and an interior typical for this class with some nice blueish and pretty big chondrules (can imagine the metal flakes you mention, Alex.)
Thanks for showing. |

My own suggested comment on this pic was somehow omitted here, so I will try again here:
