|---|---|
| Deposit | THE WHITE, FINE-GRAINED, DOLOMITIC MARBLE ZONE WHICH LOCALLY CONTAINS TALC DEPOSITS IS AT THE APPROXIMATE STRATIGRAPHIC CENTER OF THE FORMATION (VAN HORN, 1948). HE STATES THAT THE THICKNESS OF THE MARBLE IS LESS THAN 100 FEET AT THIS LOCALITY, WHICH WOULD LIMIT THE AREA FOR FUTURE EXPLORATION. |
