Jan 28, 2017 (A Wilson) - Veins of coarse white to pink and orange calcite cut the granite; the calcite contains dark green to black thorianite crystals ( .. micro"). light brown to amber plagioclase crystals measuring up to 2 cm wide, greenish blue to light green prismatic aggregates of clinopyroxene, green clinoamphibole, orange-red to brown bastnaesite as irregular patches associated with pyroxene and plagioclase, and reddish brown titanite grains. The white and pink calcite fluoresces pink under .. short" ultraviolet rays. The crystalline limestone is finely disseminated with molybdenite. pyrite (small crystals) and amber mica. It contains crystals of green apatite and greyish green prismatic aggregates of plagioclase.
