squali Posted January 7, 2011 Share Posted January 7, 2011 The blueish tint and nodules could be vivianite -a mineral that develops in marine deposits. It's hard to remember why you drained the swamp when your surrounded by alligators. Link to comment Share on other sites More sharing options...
squali Posted January 7, 2011 Share Posted January 7, 2011 if it is Vivianite it degrades under uv light and I have only had success by keeping it sealed in a film container.

-AnThOnY- Posted January 7, 2011 Author Share Posted January 7, 2011 (edited) The blue is the shell, its alot more pronounced in the picture, doesnt look that blue actually. And all the nodules look exactly like the marcasite I have Edited January 7, 2011 by -AnThOnY- Link to comment Share on other sites More sharing options...
