For mineral occurrences in the map area consult Chart A, accompanying the Sudbury-Manitoulin report.

Only the thickest and most extensive Cenozoic de posits in which bedrock outcrops are absent or scarce are shown.

Formation subdivisions of the Phanerozoic rocks are according to Liberty (1973).

cMafic dikes that intrude rocks of the Grenville Prov ince may be younger than diabase dikes cutting the Huronian rocks of the Southern Province.

The Salmay Lake Formation is probably approxi mately correlative with the Stobie arid Elsie Mountain Formations.

aMost of the mafic dikes cutting the Early Precam brian rocks of the Superior Province are probably of pre-Huronian age, although some are undoubtedly correlative with the post-Huronian Nipissing Diabase and late amphibolite, trap, and lamprophyre dikes.

Where in places a formation is too narrow to show colour, and must be represented in black, a short black bar appears in the appropriate legend block.
