Hello All, There are a few things that separate Adamana from Holbrook in my mind... The texture of the crust alone of Adamana versus that of Holbrook leaves me little doubt that the two could possibly be paired. The fusion crust of Adamana is a matte black, which contrasts sharply with the crust of recently found Holbrooks, which exhibit a typically blue/black almost shiny crust in most cases, often liberally spread with rust spots. The interior tells the same story - Adamana is a uniform brown, with chondrules poking out here and there. Recently found Holbrooks tend to be less weathered internally, if not more externally, and their dark chondrules contrast starkly with the lighter matrix, creating a much more heterogeneous appearance than that of Adamana. Adamana appears to have been weathered for a prolonged period of time in much drier conditions than all newly found Holbrooks that I've seen; its interior is uniformly weathered and yet the exterior remains virtually untouched, whereas, as can be seen by Larry's recent Holbrook find, the meteorite appears to have weathered more outside than in, to the point of decomposition, even though the matrix appears to have been less stained by rust. This, however, is at least partly due to the friability of Holbrook (Adamana does not appear to share this trait with the Holbrook fall). Whereas, when holding Adamana, I noticed that the broken edges appeared to have been somewhat polished by weathering (a very slight amount), all weathered Holbrooks that I've seen of any great size have simply fragmented given the same amount of weathering. The location of the find.... Fifteen miles is simply impossible, unless it was artificially transported. The mapped strewnfield was roughly one mile long by a half mile wide. The largest stone recovered, weighing in at ~14.5 lbs, was found at the end of this ellipse. The possibility that anything made it farther than this stone is great - it wouldn't surprise me too greatly if a 20lber was found another quarter of a mile on (it could've buried itself on impact, etc), but to say that a smaller stone continued another fifteen miles beyond the known end of the strewnfield is simply ridiculous, to say nothing of the fact that it is much too far north to even be near the same path as the body that created the Holbrook strewnfield. My $.02, Jason

Hi Here is an image of the cast of the "Venus Stone" from Bob's site. http://www.meteoriteman.com/graphics/venus.jpg He sells them for $100 each. My brother and I both picked up one at the Tucson show this year. If I remember correctly he said those were the last ones he had for sale. But you might email him to see if he has any more for sale. http://www.meteoriteman.com/misc.htm Mike -- Mike Jensen Jensen Meteorites 16730 E Ada PL Aurora, CO 80017-3137 303-337-4361 IMCA 4264 website: www.jensenmeteorites.com On 2/22/07, R.
