Mar 19, 2024 (Therese Pettigrew) - The Pelletier Township pegmatitic granite zone covers an area of at least 8 by 20 km. Dikes of pegmatitic granite intrude mafic metavolcanic rocks in the northern part of Pelletier Township, as exposed on the Prune Creek Road and adjacent logging roads within the Quetico–Wawa subprovincial boundary zone. These dikes, initially mapped by Berger (1985), range from 1 to 5 m in width, and consist of garnet-muscovite potassic pegmatite and garnet-muscovite fine-grained leucogranite, as at 02-FWB-09 (UTM 305498E 544892N, Zone 17) or sodic pegmatite as at 02-JBS-14 (UTM 305989E 5448581N, Zone 17). Black tourmaline sporadically occurs as intergrowths with quartz in a 5 m thick, garnet-muscovite potassic pegmatite at 02-FWB-09. Sample 02-FWB-62-01 returned 1229 ppm Rb and 40 ppm Cs from a white blocky potassium feldspar from quartz-rich patch in muscovite Mono - Fertile and Peraluminous Granites and Related Rare-Element Mineralization in Pegmatites, North-Central and Northeastern Superior Province Publication Number:
