General comments

Subject category Comment text
Deposit THE DEPOSIT CONSISTS OF SEVERAL LENSES OF PHOSPHATE-BEARING MATERIAL. MOST OF THE LENSES ARE AT OR NEAR THE BASE OF A GREEN SILTSTONE; A FEW ARE NEAR THE TOP OF THE UNDERLYING YELLOW AND RED SILTSTONE. THE PHOSPHATE BEDS RANGE FROM 0 TO 30 M THICK. THE LENGTH OF MOST LENSES IS LESS THAN 0.5 KM, BUT SOME ARE AS MUCH AS 1.5 KM LONG ALONG STRIKE. THE BEDS ARE FOLDED AND FAULTED. THE MAIN PHOSPHATE MINERAL IS CALCIUM PHOSPHATE OF THE APATITE GROUP. AT THE SURFACE, ACID WEATHERING HAS ALTERED ALL OF THE APATITE TO AN ALUMINUM PHOSPHATE MINERAL, WAVELLITE.
