Hveragerthi Posted May 10, 2007 Share Posted May 10, 2007 I found this rock that I found pretty interesting. The rock is shaped like a turtle shell. Curved and smooth on the bottom. The top is grooved. There is a black crust over most of the rock. It is strongly magnetic at various parts of the rock. When I cut it open I found it contains occasional balls of iron, which are the only magnetic areas. The first attached photo shows the top. The second photo shows the bottom. And the third photo shows a cut piece showing the interior with one of the balls of iron. Quote Link to comment Share on other sites More sharing options...
