General comments

Subject category Comment text
Deposit LIMESTONE OCCURS IN LENSES OF VARIABLE ORIENTATION AND HAS BEEN THINNED IN PLACES BY FOLDING. THE LIMESTONE CONTAINS MINOR DISSEMINATIONS OF GRAPHITE AND, NEAR THE MARGINS, SPORADIC BANDS OF CHLORITE AND COARSE HORNBLENDE HORNFELS. ONE IRREGULAR BODY IS ESSENTIALLY CONTINUOUS FOR 1550 FT AND RANGES FROM 6-50 FT IN THICKNESS. OTHER LENSES ARE 100-300 FT LONG AND 16-30 FT THICK. THE LIMESTONE HAS A DISTINCT ODOR OF H2S WHEN FRESHLY BROKEN.
