| Deposit | DIP IS VARIABLE TO NEAR VERTICAL. BARITE OCCURS IN RESIDUAL CLAYS AND AS VEINS AND REPLACEMENT MASSES IN BLOCKS OF MARBLE FOUND IN THE RESIDUUM. MICA SCHISTS FORM THE WALL ROCK AND CONTAINS ABUNDANT MAGNETITE GRAINS. STRIKE AND DIP VARYS LOCALLY. THE CLAY IS DERIVED FROM MARBLE OF THE MOUNT ATHOS FORMATION. OLD WORKINGS SHOW THE ORE BODY TO BE QUITE EXTENSIVE, AT LEAST 100 FT (30.5 M) WIDE BY 700 FT (213.4 M) LONG AND PROBABLY LONGER. |
