Hi Bernd, I can't seem to post to the list but I have one crusted piece of Carancas and here is what I see: The slickensides are real and I don't think I've ever seen anything quite like them. They're black and look like crust but their laminar appearance suggests either slickensides or some kind of two-dimensional "shock sheath." It's as if you took a shock vein and spread it out across a surface. On the other hand, the crust has the appearance of being cleaved so maybe it really is slickensides. In addition there are a number of fine black shock veins threading the matrix. Part of the matrix is grey and a bit dusty in appearance. Under the slickensides however it's very white and I can see a shock vein or two in the white. I searched my 1.5g piece carefully but couldn't find any sign of a chondrule. This surprised me given its H4/5 classification. No obvious troilite inclusions stand out. Some of the matrix appears to be stained brown, no doubt from clay. And as for smell, there was none that I could detect but I was overcome with .... curiosity :-) Bob
