[QUOTE="user 4386, post: 577377, member: 4386"] Hi Sydney... First question is - are you absolutely sure that they are in a volcanic rock (I read your other post on this)? It is difficult to tell from a photo (despite your posting good photos). Just had a slight look of a sedimentary rock. Secondly - what is the mineral in the spheres - I think you said "iron" but what mineral of iron, and what were its features that you used to identify it. Such things (especially gold, which this is not) are usually introduced to volcanic rocks (or whatever) AFTER the rock has formed, and are otherwise commonly not related to the host rock itself in any way. Usually deposited by later fluids that travel through a fracture in the rock. Location might give a clue if you wanted to give it, here or PM. [/QUOTE]
