Mann 2

Located 5.2 km southwest of Mann 1 and 6.5 km north-northeast of the North Red Wine complex the Mann 2 occurrence is a long narrow body of about 3.5 km x 100-200 m. It lies within deformed rocks of the Letitia Lake Group, and is correlated by Curtis and Currie (1981, Fig. 39) with their blue-black melanocratic gneiss (unit 7), and interpreted as a dyke phase of the agpaitic rocks of the Red Wine complexes (031-00-157 and Fig. 1_80). The rocks are schistose with augen-like albite crystals up to 1 cm long and disc-like schlieren of pyroxene up to 2 cm in diameter. The general mineralogy is nepheline and arfvedsonite, with albite, blue omphacitic pyroxene and variable, but minor, pectolite, lamprophyllite, murmanite, ramsayite, astrophyllite, aenigmatite, catapleite etc.
