Spherulitic Rhyolite Geode Mineral Specimen measuring at 4" x 3" x 2.25" weighing 475.6g. This specimen has earthy brown gray white colors with a touch of mauve purple and light green colors. The geode is filled with bladed calcite, and drusy siderite and was recovered in 1997 on the northern edge of the Mt Skukum Caldera Complex near Berney Creek and Vesuvius Hill Yukon Territory in Canada. This fine specimen is part of an Eocene age pyroclastic volcanic flow of felsic rocks and has bubbly inclusions throughout the stone matrix, interesting mineral and a sure conversation piece.
