Abstract : The r from the North Star Mine in the northern portion of the area to Mafeking in the south. The purpose of the study was to test the feasibility of explosion seismology studies in this portion of the Precambrian shield and, if warranted, to interpret the crustal structure in this areesults are presented of a deep crustal seismic survey executed during the summer of 1961 in an area in central western Manitoba. It consisted of a seismic profile along Manitoba provincial highway No. 10 from the North Star Mine in the northern portion of the area to Mafeking in the south. The purpose of the study was to test the feasibility of explosion seismology studies in this portion of the Precambrian shield and, if warranted, to interpret the crustal structure in this area where pronounced gravity anomalies suggest a major warping of the earth's crust. Eight shots were detonated within the abandoned water-filled workings at the North Star Mine and seismic signals were received at distances up to 135 miles to the south. (Author)
