Come on, they meteorites are often covered with frothy blue-black crust, sometimes 2 or 3 mm thick, it flackes off, it was caused by the fusion of iron minerals while burning at thousands of degrees on entry, exactly the same way silicates form fusion crusts on stones. Thus, we have two different types of materials, burning, and when they land, they have a surface of crust comprised of molten material due to heat alteration. How can that not be called a fusion crust? Michael Farmer Received on Sun 07 Jan 2007 01:34:23 PM PST |
