a This legend is a field legend that locally incorporates the results of

laboratory investigations, including petrography and geochemistry.b This is a legend common to Ontario Geological Survey Preliminary

Maps P.3548, P.3549, P.3550, P.3551 and P.3552. Thus, not all

map units in the legend may appear on the map face.c A �gneiss association� is an informal stratigraphic term, introduced by

Culshaw et al. (1988), that is primarily based on rock type, but which

also may contain information with respect to plutonic history,

metamorphism or intrusion of mafic dikes. If it were decided to

formally name a "gneiss association" as a lithodemic unit under the

1983 North American Stratigraphic Code, in most cases, they would

correspond to a suite or a complex.
