squalicorax Posted December 5, 2012 Share Posted December 5, 2012 Possibly some sort of Porphyritic basaltic rock? My Flickr Page of My Collection: http://www.flickr.com/photos/79424101@N00/sets Link to comment Share on other sites More sharing options...
evren Posted December 5, 2012 Share Posted December 5, 2012 I've seen stuff like this formed from power lines coming down and "welding" gravel and dirt together. For simplicities sake I'd agree that it's probably some sort of extrusive basaltic lava. Link to comment Share on other sites More sharing options...
Auspex Posted December 5, 2012 Share Posted December 5, 2012 It could also be slag from iron ore refining.
