Ore body information

  • General form TABULAR, BEDDED
    Thickness 10.67M

Comments on the geologic information

  • GYPSUM IS EXPOSED IN THIS AREA INTERBEDDED WITH LIMESTONE, SHALE, AND CLAY. GYPSUM BEDS RANGED FROM 10 TO 20 FT THICK. LOW PURITY OF THE GYPSUM, STRUCTURAL COMPLICATIONS, FAULTING, AND IGNEOUS INTRUSION LIMIT THE COMMERCIAL POTENTIAL.
