Economic information

Comments on the geologic information

  • Geologic Description = Sample from an 8 ft. zone of rubble of black chert, black paper shale, black shaly dolomite, and oolitic phosphate rocks in the Carboniferous Lisburne Group; there probably are 2 horizons (each about 6 in. thick) of phosphate rock (Patton and Matzko, 1959, p. 11-12). Stratigraphic position in Lisburne Group uncertain.
  • Age = Carboniferous
