Mike Murphy Posted October 24, 2008 Share Posted October 24, 2008 water plant? This specimen is not a plant fossil. The rock is a volcanic intrusive rock (probably basalt) with phenocrysts of feldspar (pinkish tabular crystals or prisms) and olivine (green tabular crystals or prisms). The rock has been water-worm to a smooth surface. Regards, Mike Link to comment Share on other sites More sharing options...
Guest solius symbiosus Posted October 24, 2008 Share Posted October 24, 2008 I think the second one is a type of porphyry. That is what I thought when I first saw it, but the larger grains of the xls had me thinking peridotite. That said, I know next to nothing about hard rock geology.

Ramo Posted October 25, 2008 Share Posted October 25, 2008 Welcome to the forum. Did you get a chance to go down the Alpine slide a Lutsen? That thing is a blast! There are some nice gravel pits in that area with very nice Agates. If you find yourself up that way again, I'd deffinately check them out.
