Subject	has color	has weather resistance	has texture	has definition	is part of	has composition	has thickness	is a kind of
iron meteorite fusion crust	blue-black to black	very low	resembling freshly welded steel			magnetite (iron oxide)	small fraction of a millimeter	iron meteorite characteristic
primary fusion crust	black except for rare iron-poor meteorites			thin layer of ablated material that forms before a potential meteoroid break up from the beginning of incandescent flight until dark flight	meteorite		greater than secondary fusion crust	meteorite fusion crust
secondary fusion crust	black except for rare iron-poor meteorites			forms on a freshly broken face if the meteoroid break up occurs before reaching the retardation point	meteorite		smaller than primary fusion crust and not as smooth because the broken face suffers less ablation	meteorite fusion crust
stone meteorite fusion crust	black except for rare iron-poor meteorites	high	dull black for most stone meteorites, or glassy for low melting point eucrites		stone meteorite	mostly silicate glass with some magnetite	less than one millimeter to several millimeters	meteorite fusion crust
