New Members SaintSakuraMN Posted February 25 New Members Share Posted February 25 Found several of these on a beach in Grand Marais, MN on Lake Superior. The light colored part is a bit rougher feeling and the red/maroon knobs or nodules are quite hard and smooth and raised. I can’t find anything on them…someone mentioned in another forum possibly Rapakivi Granite or Granite Mica Schist but I think they seem a bit different than the images I saw of those. The largest one has a few tiny pockets of crystals. Thoughts? Link to comment Share on other sites More sharing options...
Ludwigia Posted February 25 Share Posted February 25 First of all, these are not fossils, so although you probably already know that, you should have posted under "Rocks & Minerals", but never mind. I think it's possible that the red nodules might be worn garnet, making the stones an extremely eroded metamorphic garnet mica schist. Greetings from the Lake of Constance.

Mark Kmiecik Posted February 25 Share Posted February 25 I think they are taconite pellets, bleached by exposure to sun and surf. A lot of them in that area missed the bin while loading the freighters and have washed up on area beaches. 1 Mark. Fossil hunting is easy -- they don't run away when you shoot at them!
