General comments

Subject category Comment text
Deposit LENSES AND STRINGERS OF PYROLUSITE ALONG BEDDING IN SILICIFIED CHERT AND ARGILLITE. N20W VERTICAL SHEAR ZONE CUTS -N20E BEDDING, N20E STEEP FRACTURE ZONE. MANGANESE OXIDES AND B-LACK TO BROWN JASPEROID APPEAR TO BE ASSOCIATED WITH THE NW ST-RUCTURE AS MOST BEDDING REPLACEMENT OCCURS ALONG IT; ROCK IN A-REA OF STRUCTURAL INTERSECTION LACED WITH SILICA VEINLETS. MAS-SIVE PODS OF JASPEROID OCCUR IN EAST WALL OF PIT; SOFTER, GOSS-ANY MNO REPLACEMENT ALONG BEDDING TO WEST OF JASPEROID. IT IS -POSSIBLE THAT THE JASPEROID FORMED ALONG THE STEEP FAULT INTER-SECTION. CRYSTALLINE PYROLUSITE COATS FRACTURES IN JASPEROID; -ROCKS IN DUMPS APPEAR TO BE MASSIVE PYROLUSITE, BUT ONLY SURFA-CE COATING IS PRESENT.
