secondary fusion crust
subject			fact

secondary fusion crust	is a part of meteorite
	is a kind of meteorite fusion crust
	has definition forms on a freshly broken face if the meteoroid break up occurs before reaching the retardation point
	has thickness smaller than primary fusion crust and not as smooth because the broken face suffers less ablation
meteorite fusion crust	has extent directly proportional to the initial velocity of a meteoroid
	has color black except for rare iron-poor meteorites
	has texture
	has weather resistance
	has composition
	is different from interior of meteorite
