moodorf Posted July 28 Share Posted July 28 (edited) I broke apart a very weathered favosite coral fossil found at my spot, looking for vugs. This time I found the inside had some strange lustrous component to it. I'm still pretty new to rocks so I have no idea what it is inside of this particular piece. Here's a fragment. It's not silvery, it's just that the luster makes it look silvery. Here's the outside Any help appreciated. Thanks for looking Edited July 28 by moodorf Link to comment Share on other sites More sharing options...
FranzBernhard Posted July 28 Share Posted July 28 Probably galena. Pic before last pic shows typical cubic cleaveage of galena. Franz Bernhard 1 Link to comment Share on other sites More sharing options...
moodorf Posted July 28 Author Share Posted July 28 Hmmm Galena would be pretty cool Link to comment Share on other sites More sharing options...
ynot Posted July 28 Share Posted July 28 Not seeing any coral or other fossil here. Looks like a piece of pegmatite with several different minerals. The shiny dark grey could be galina. 1 Link to comment Share on other sites More sharing options...
moodorf Posted July 28 Author Share Posted July 28 Yeah I did crack open many a rock that day, could be that it was one of the ones that wasn't a fossil. Link to comment Share on other sites More sharing options...
