Geological Compilation of the Northern Sask Craton and Southern Glennie–Flin Flon Complex in the Pelican Narrows Area, Saskatchewan
Southeast Sheet: Kakinagimak-Mari Lakes Area (parts of 63M/01 and 63N/04)
by R.O. Maxeiner and K.E. Ashton This map was printed from the geologist’s digital file. Geological data were processed using Microsoft Access and ArcView 10 software. Base maps were compiled from 1:50 000 scale digital topographic maps licensed from Saskatchewan Information Services Corporation. Grid coordinates are NAD 83 UTM zone 13. The map was processed overall using ArcView 10 software. The map is available on the internet at www.er.gov.sk.ca. This map may be referenced as: Maxeiner, R.O. and Ashton, K.E. (2012): Geological compilation of the northern Sask craton and southern Glennie–Flin Flon complex in the Pelican Narrows area, Saskatchewan, southeast sheet: Kakinagimak-Mari lakes area (parts of 63M/01 and 63N/04); Sask.
