Description
"An orbicular bead is a stone that is round like a ball and is formed under particular environmental conditions. Orbicular beads are mostly found in granite. This stone is rare, serving as special data for geology and as important data in researching how rocks are formed. The gabbroid in Jeonpo-dong in Busan is an orbicular bead in a gabbro with length of 400m and width of 300m. Orbicular beads have diameter of 1~ 10cm and dark grey or light grey color. Most orbicular beads are found in granite, but the orbicular bead in Jeonpo-dong is found in a gabbro. The gabbroid has high research value because it is found intact. The orbicular gabbro in jeonpo-dong is designated and conserved as a Natural Monument because it is a rare rock reported only to the scientific world in Asia."
