Plantguy Posted October 31, 2010 Share Posted October 31, 2010 Hey gang, mighty impressive stuff you all have there--super, especially the traces of color! Polk a dot preservation still kills me! Drool. I think NAL hunter already mentioned malachite replacement....here's some malachite permineralized wood from near Interstate 40, north of Thoreau, New Mexico. I added a spritz of water to bring out the green color! Undetermined age and species. Regards, Chris Link to comment Share on other sites More sharing options...
Ludwigia Posted October 31, 2010 Share Posted October 31, 2010 Hi, Getting back to substances, Baryt hasn't been mentioned yet. The "Steinhardter Erbsen"(literally: Peas from Steinhardt, a small town in Rheinland-Pfalz) are baryt concretions formed during the Oligocene containing plant substance like pine cones, leaves or branches which have also been metamorphosed into baryt. They're well known above and beyond the German borders as witnessed by the link to the Dutch Forum which I'm giving you. http://english.fossiel.net/determinatie/identificationsearch.php?vindpl_id=229 Best wishes, Roger Greetings from the Lake of Constance.
