Hi everyone, Many pieces of broken Chelyabinsk specimens display what appears like fusion crust over slickensides, but is that what it really is? I've talked with Blaine Reed and he thinks we're seeing blackish shock veins (planes really) where the meteorite split along a line of weakness. He even mentioned a piece he's seen where a large shock vein in the matrix leads directly to the broken, dark face. Assuming Chelyabinsk shows both slickensides and shock vein planes, how do you tell them apart? Thanks for your thoughts. Bob ______________________________________________
