Rare element minerals Nb, Ta, monazite, etc. was found in post-cambrian pegmatite. Minerals identifted are columbite and monazite, possible containing uraniobite and germanium--manganese garnet. Most of the minerals are produced dispersedly in the zone of massive feldspar quartz pn the pegmatite. (W.D.M.)
