Deposit ROUGHLY CIRCULAR TO POD-SHAPED PEGMATITE IS CONCENTRICALLY ZONED AND CONTAINS 1) 5- TO 20-FT-THICK WALL ZONE OF GRAPHIC GRANITE WITH SCATTERED BIOTITE BLADES; 2) OUTER INTERMEDIATE ZONE ENCOMPASSING THE MIDDLE INTERMEDIATE OF BIOTITE WITH THORITE AND CYRTOLITE AGGREGATES IN MICROCLINE-PERTHITE; 3) POORLY DEVELOPED INNER INTERMEDIATE ZONE OF FLUORITE; 4) QUARTZ CORE. FERGUSONITE OCCURS IN OUTER INTERMEDIATE ZONE.
Deposit 9 VEINS AT STOCKTON MINE, ALL STRIKE NE, PARALLEL TO SCHISTOSITY OF HOST ROCK. VEINS ARE PEGMATITIC IN CHARACTER; GERTRUDE AND STOCKTON ARE MAIN VEINS IN DISTRICT
