Abstract:
The mineralogic and geochemical investigation showed: (1) bulk As and Sb concentrations within the Avon Park are low; (2) As values ranged from <0.1 to 30.8 mg/kg and Sb from <0.1 to 6.76 mg/kg; (3) average values were 2.07 mg/kg As and 0.26 mg/kg Sb; (4) pyrite was present as framboids, hollow framboid rings, small irregularly shaped pieces with topography, and euhedral crystals; it was typically associated with oxidized laminations, fractures, and molds; (5) the framboid rings may have been precipitated by a bacteria making them biogenic; (6) euhedral pyrites contained significantly less As than other morphologies; (7) individual pyrites ranged from <0.1 to 1.43 wt% As while Sb ranged from <0.1 to .44 wt%; (8) the samples from zones of high permeability had lower As and Sb averages than those of the other samples: 0.98 mg/kg As and 0.18 mg/kg Sb versus 1.32 mg/kg As and 0.19 mg/kg Sb for interval and 2.9 mg/kg As and 0.34 mg/kg Sb for targeted samples.
