The magnesite is massive pearl-white, coarsely crystalline with a buff colored weathered surface. It grades laterally into a grey, psuedo-fenestral dolomite and is underlain by a fine- grained dolomite with 1 to 5 centimetre thick chert lenses. Magnesite occurs as one centimetre long crystals and appears to replace dolomite near the basal contact. Locally the larger crystals within a matrix of 0.5 millimetre grains of magnesite give a distinct "porphyritic" (bimodal?) appearance. Considerable silica is present as scattered remnants of cherty patches. EMPR AR 1964-198 EMPR FIELDWORK *1992, pp. 467-470 EMPR OF 1987-13
