5203 |a"A marine geophysical survey program was conducted in Lake Simcoe, Ontario in September 1992, and May and June, 1993 as part of a program to better understand the lake bottom and the subbottom geology. This Open File report provides a seismostratigraphic framework for the ongoing environmental assessment of Lake Simcoe and of similar lakes, and to assess seismic hazards in southern Ontario. A 4 km by 4 km survey grid covered the lake, with more closely-spaced survey lines in Kempenfelt Bay and Cook’s Bay. High-resolution single- and multichannel seismic reflection profiling were used to delineate late- and post-glacial sedimentary strata, structures and lakefloor features. Acoustic basement is Ordovician sedimentary rock, overlain by three seismostratigraphic sequences within the unconsolidated sediments"--Abstract, p. iii.
