Hey guys, this is my first post. I just bought my first metal detector a couple of days ago.. I have dug up my yard and some areas around my house. Anyway I was doing some digging at Lake Michigan and I got a huge Ping from this rock. I would like to know if anyone knows what type of rocks would ping? It is a dark almost black color on the outside, but when I broke a peice off it has a silvery color to it. It is lighter then most rocks. I had someone look at it and they seem to think it might be meteorite. Would the metal detector pick up meteorite? Also does anyone know a way to find out for sure. Thanks everyone for there advice. I will post up my finds over the last couple of days soon.
	
		
			
		
		
	
				
			
						
					
 
  What you have found sounds very familiar to me.  Several times I have dug up large targets that look like what you found, a lightweight, dark, fist sized, black blob with shiny metallic particles that you can break up with your hand.  I'm pretty certain that what you have found is the remains of a charcoal barbecue, probably off of someone's boat.  Boaters will sometimes dump the foil and charcoal overboard in a wadded up lump of aluminium foil, charcoal and grease.  This gets compressed over time by wave action and sand.  Eventually you wind up with a rock that is lightweight (aluminium) and dark (charcoal).
