Rodingite (metamorphosed basic tuff) xenoliths in serpentine. A scientific monument here is dedicated to a small find of micro kosmochlor crystals, but the outcrop behind the monument has completely disappeared. Nearby are outcrops of unusually pure white jadeite (not cuttable). A 6 x 6 km ultramafic body with chromium-rich minerals.
