| Deposit | TALC OCCURS 20 TO 21 KM NORTH OF CACULE WITHIN A BELT OF MIGMATIC GNEISSES HAVING LAYERS OF CALC-SILICATES. THE 2 TALC-BEARING LAYERS STRIKE N20-30E, AND ARE 7 AND 20 METERS THICK. THE TALC IS DERIVED FROM THE ALTERATION OF ACTINOLITE AND OTHER CA-MG SILICATES IN THE GNEISS. THE PRESENCE OF NUMEROUS IMPURITIES AND LACK OF PERSISTENCE WITH DEPTH MAKE THESE DEPOSITS UNECONOMIC. |
