| Deposit | GARNETS UP TO 13 MM IN PEGMATITE CUTTING PRECAMBRIAN SCHIST |
| Deposit | "Minor quantities of fergusonite(?) occur in a pegmatite that cuts pre-Cambrian tourmalinized mica schist and gneiess. The pegmatite strikes N50E and dips 85NW with exposures for 140 ft. The pegmatite was mined for mica, beryl, and tantalite in 1942 and 1943." [Bull. 50, 1966, p. 220.] |
| Deposit | "The pegmatite cuts pre-Cambrian tourmalinized mica schist and gneiss. There are two open pits and two timbered shafts. The pegmatite strikes N50E and dips 85 NW with exposures for 140 ft. Seventy-five feet north of the main pegmatite body is a quartz-potash feldspar-mica-plagioclase pegmatite which stirkes north and is vertical; it is apparently not connected with the larger body. Cover prevents an accurate estimate of the extent of the pegmatite beyond the workings. Muscovite is abundant near the hanging wall in the larger pegmatite. The books are light-green speckled with magnetite, and ruled. Only a small quantity is of sheet quality; about 10% is punch quality. Up to 1943, 38,000 lbs of scrap mica, 2,500 lbs of punch and 500 lbs of rifted mica were produced. Two tons of beryl (12.39% BeO) were shipped up to 1942. The beryl crystals are corroded. Small tantalite crystals (45% Ta2O3) are rare in this district; about 85 lbs were recovered up to 1943. Minor accessory minerals include fergusonite(?) and pink euhedral garnets and orange subhedral garnets about 13mm in diameter." (Bull. 50, p. 132) |
