"In August 1979 the Co-CRUST (Consortium for Crustal Reconnaissance Using Seismic Techniques) group continued its cooperative seismic survey program in the southern part of Manitoba and Saskatchewan. The first phase of the project was undertaken in July1977 and its findings were reported by Green and Stephenson (1978) and Green et al. {1980). The rationale of the study was to obtain information about the nature of the boundary zone between the Churchill and Superior Tectonic Provinces of the Canadian Shield. The surface geological characteristics of the transition zone and the associated geophysical anomalies were described by Green and Stephenson {1978). This report includes a brief outline of the objectives, the geographic setting of the 1979 portion of the survey, field procedures, field parameters, digital data tape formats, and a short summary of the preliminary interpretation"--Introd., p. 1.
