Type of structure Local
Structure description Solution Sags Are The Only Structural Deformations.

Ore body information

  • General form BLANKET (COVERS 2000 SQ MI OF THE COASTAL PLAIN)
    Dip SLOPES OF 5 FT/MILE ARE COMMON TO BONE VALLEY FM.

Controls for ore emplacement

  • Large Scale Barrier Bars May Have Significantly Influenced Deposition.

Comments on the geologic information

  • THE BONE VALLEY FM WAS DEPOSITED ON THE ERODED SURFACE OF THE HAWTHORN FM. BY A TRANSGRESSING SEA THAT REWORKED AND SORTED THE HIGHLY PHOSPHATIC RESIDUAL OF THEHAWTHORN FM. PHOSPHATE RECOVERED IS FROM THE LOWER BONE VALLEY-WHICH IS LESS WEATHERED-AND THE UPPER RESIDUAL PART OF THE HAWTHORN. RIGGS (1967) REDEFINED THE STRATIGRAPHY CREATING HAWTHORN GROUP WHICHINCLUDES ROCKS PREVIOUSLY PLACED IN HAWTHORN AND BONE VALLEY FMS. BONE VALLEY FM. WAS THEN SUBDIVIDED INTO 11 MEMBERS.
