JeffD Posted October 7, 2011 Share Posted October 7, 2011 (edited) Hello, I found these along a dried up river in Az. I believe them to be nodules...could anybody confirm this for me? I saw a recent topic addressing the same issue but his nodule looks almost nothing like mine. I have a variety varying in size, shape, and weight. Is so what should I do with them...are they worth splitting? They look cool as is for display pieces and I would hate to ruin that...help! The last picture only has my three biggest ones. The largest is about the size of a fist. Other two about the size of a ping pong ball. Edited October 7, 2011 by JeffD Link to comment Share on other sites More sharing options...
Coco Posted October 7, 2011 Share Posted October 7, 2011 Hi, They look like quartz geodes. It is not sure, but maybe that there would be crystals inside.

dhk Posted October 8, 2011 Share Posted October 8, 2011 I'm going with the geodes. Split one open and see what you find inside. Link to comment Share on other sites More sharing options...
Indy Posted October 8, 2011 Share Posted October 8, 2011 These are "quartz geodes"...at least that is what I've always called them, and are commonly found in stream beds here in Missouri. It's been a long time since I broke one open but calling on memory... they have low quality brittle quarts inside. Noticed another post on our forum of similar shaped quartz geodes found in Missouri: My link Flash from the Past (Show Us Your Fossils)MAPS Fossil Show Link to comment Share on other sites More sharing options...
JeffD Posted October 8, 2011 Author Share Posted October 8, 2011 Thanks for your help everybody. I will split one of the smaller ones open and post pictures of it. I am very timid about the larger one because I would not want to ruin it haha. But maybe one day soon I will muster up the will!! lol thanks again Link to comment Share on other sites More sharing options...
Vordigern Posted October 9, 2011 Share Posted October 9, 2011 if the small one does turn out to be a geode you might be able to cut the larger one with a tile saw, good luck Link to comment Share on other sites More sharing options...
