Dear collectors,

Here is the fourth Rohr collection offering.

CHELYABINSK, Russia: (LL5). Fell February 15, 2013.
This is a nice complete and fresh individual. It is pretty obvious that this was picked up early after the fall. Aside from a tiny (about 1mm x 1mm) late flight chip, this stone is completely covered in thick primary fusion crust. The photo of this might show some crust coloration that looks like rusting – dark reddish brown areas. This may indeed be oxidation BUT it formed during the fall and NOT from later weathering on the ground after the fall. This is not uncommon on fresh Chelyabinsk specimens. I have also seen this on Allende specimens but not all that many other meteorites. This also has an interesting 2mm x 2mm metal nugget poking out of the surface. A great fresh piece (that Linton probably paid a big premium for as he undoubtedly got this soon after the fall) that is in a labeled membrane box.
    10.3 gram fresh complete individual – 25mm x 16mm x 15mm -  SOLD
But I have others- contact me.



GIBEON, Namibia: Fine octahedrite (IVA). Found 1836.
This is a small complete individual that has been wire-brushed moderately. It has an overall dark brownish black color but there are some areas of original exterior (dark orange as I believe that this has also been oiled at some point) showing that this specimen is indeed a small Gibeon. Gibeons of all sizes have become very much in demand and prices have increased to quite surprising levels lately. This also comes with a Linton Rohr collection label.
    18.1 grams – 32mm x 15mm x 11mm - SOLD 

NWA (unstudied):
This is an assortment of 10 relatively fresh and mostly complete stones. One piece (the largest) looks like it could be NWA (869) but I am not going to cut it to find out. The others have a bit of a different look to them. Regardless, these would be great for people that have customers for small things or as gifts for people that just want to own a nice small stone meteorite.
    52.5g lot of 10 stones - SOLD 
But I have others- contact me.

NWA (2871): Primitive achondrite (Lodranite). Found 2004. Tkw = 3500+ grams.
This is a specimen that Linton got from me years ago and likely at a much higher price. I think I pretty much sold out of this stuff at nearly $70/g back when I had a good amount of it (I think I might have a couple small piece in my inventory somewhere). This is an end piece/ cut fragment that shows a granular/ crystalline texture on both the cut surface and the natural exterior.
    3.74 gram end piece – 20mm x 20mm x 5mm - SOLD 
But I have others- contact me.

NWA (4502): Carbonaceous chondrite (CV3). Found 2008. Tkw = about 35 kilograms.
This is another piece that Linton got from me years ago. It is an end piece that shows a nice smooth (wind-polished), rounded back side so this is not a broken fragment but likely a true ½ of an individual. The interior is dark, as is usual for this particular meteorite, but lots of (oblong) chondrules are visible on close inspection. This is an unusual CV meteorite in that it shows quite strong attraction to a magnet. Because of this, this material was first believed to be more likely a weathered CR meteorite before research work was done to sort out the issue.
    24.5 gram end piece – 55mm x 20mm x 10mm - SOLD
But I have others- contact me.

OUM DREGA, Western Sahara: (H3-5). Fell October 16, 2003. Tkw = around 17kilograms.
I kind of forgot about this stuff. Pieces of it were not available for very long. I know I have had it and sold it in the past, but never got enough of this meteorite to have much of it in inventory (unlike Chergach and Bassikounou which are my go-to fresh fall affordable stones in my inventory). This is technically a complete individual, though it looks like it has an end (20mm x 11mm) fractured off of it. This end, however, does show small spots of fusion crust formed on some of the higher spots so this “fracture” is really an area of very light secondary crust. The remainder of the stone is covered by nice thick black primary crust. This piece comes with a Hupe collection label that lists the name as “Amgala” – which is what this material was being called before the research work and reporting were completely done.
    15.0 gram complete individual – 30mm x 18mm x 14mm - $80

SIKHOTE-ALIN, Russia: Coarsest octahedrite (IIAB). Fell February 12, 1947.
This is an interesting piece. At first glance, it looks like a pretty typical but blocky shrapnel fragment. However, on closer inspection, it has smooth areas that look like they were fusion crusted/ thumb-printed surfaces (unfortunately, this has been wire brushed so any actual fusion crust on these areas is now gone). So, it seems that this specimen is more likely a “half-breed”- a piece that is indeed a shrapnel fragment but yet still has some of the sculpted surface that was on the exterior of the original meteorite mass before it got ripped apart in hitting the ground. I have seen some of these type things in the past but they are fairly rare. This comes with a Rohr collection label.
    90.8 gram half-breed – 30mm x 30mm x 20mm - SOLD
