idahogold Posted February 1, 2019 Share Posted February 1, 2019 I'd say Felsic extrusive that has the outside edge weathered or clay covering exfoliating...may be a welded tuff...or rhyolite Link to comment Share on other sites More sharing options...
klunker Posted February 2, 2019 Share Posted February 2, 2019 It's definitely Seescandyite. Composed of marsmalloine encrusted with chocolatite. Where in the heck did you find that? Link to comment Share on other sites More sharing options...
