patatt Posted March 15 Share Posted March 15 Could anyone help in telling me what this might be. Found out magnets will stick to the dark part but not the split part also noticed the nipple part has a shape on one side that lines up with the oblong groove I know nothing about stones, but the markings on this seem very strange Quote Link to comment Share on other sites More sharing options...
chrisski Posted March 15 Share Posted March 15 (edited) Don’t mistake my response to have any special knowledge. I suspect this could be an iron ore, perhaps the black magnetic ore is magnetite and the brown is hematite. Magnetite will stick to a magnet, hematite is extremely weak on a magnet. The holes in the brown ore make me think it could also be basalt, a fancy name for a category of lava flow. could be round if it was rolled in a river the right way. River rocks tend to be round. Pediment is angled rocks that could have broke from sun and freezing and tends to be angled. Edited March 15 by chrisski 3 Quote Link to comment Share on other sites More sharing options...
