I googled meteorite. Most suspected meteorites are not. There are places that will test your rock for free but you could lose 20 % of the specimen to their tests. This looks like an iron meterite image Google has. My problem is that the whole thing would have that burned crust not just one side. I will look into the address of one of those sites where you can send it to have it tested.

This rock has vesicles. Meteorites do not have vesicles. The burnt outer crust should be glass if this is a meteorite.

Looks like a volcanic rock to me, they can be heavy or light. Check the area you found it for any old volcanoes near by. Here is a photo of gold in volcanic rock. alt text

My guess is Slag. Often confused with meteorites. Some will also be magnetic from the inclosed iron.   If there was a refinery nearby from where you found it, it may explain where it came :)

The reason I know this is because I found a similar rock like these images and also a black glass/obsidian type in the same field and it was driving me nuts trying to find out what it was.... so, I asked a university professor of geology in my city (McGill University) ....three weeks later I got an Answer lol

Did some research; there was, in fact, an industrial refinery nearby.  The yellow crystal-ish veins are crystilized impurities.   Thought I would save you some time and tell you about my experience...I still kept all the rocks! Loll
