Not at all, I found this rock in the kern river here in Southern CaliforniaKAbron, thanks for putting it down! Bring it to your university geology dept. they should be able to tell you? It looks to have a fusion crust and regmaglypts?
But the river can also cause that to some degree, but not it being metallic? there is a possibility of it being magnetite or hematite? if you don't mind me asking where did you find it? HH
