Comment (Deposit): THE PEGMATITE CONSISTS OF TWO UNITS: A WALL ZONE OF REDDISH MICROCLINE, WHITE PLAGIOCLASE (AB 87) AND COLORLESS QUARTZ TO 4 INCHES LONG, AND A CORE OF QUARTZ AND LIGHT RED MICROCLINE WITH BIOTITE ALTERED TO CHLORITE. EUXENITE ASSOCIATED WITH MINOR MONAZITE MOSTLY IN WALL ZONE NEAR CORE. RADIOACTIVE ILMENITE ENCLOSED IN PARALLEL SHEAFS FO BIOTITE IN CORE ALONG ITS MARGINS. ALLANITE IN QUARTZ PEGMATITE CUT BY BIOTITE BLADES.
