| Abstract | As part of a reconnaissance sub-bottom acoustic profiling (SAP) survey, eleven SAP were collected from Lac Macamic, Quebec, on July 21, 2014. Good penetration of the sub-bottom was obtained in both of
the profiled bays. Three facies can be identified within the SAP returns that represent lacustrine, glaciolacustrine and mass movement deposits. The profiles collected from Lac Macamic demonstrate the presence of mass movement deposits within this
basin. |
| Summary | (Plain Language Summary, not published)
This report is one of eight that are being released concurrently. All contain the results of geophysical surveys of the bed of a selected lakes in the
area of Rouyn-Noranada-Kirkland Lake, Quebec-Ontario. The results from some of the lakes show evidence of ancient landslides that occurred in a large glacial lake. These results will be used in a study that is investigating whether the landslides
were triggered by an ancient earthquake. |
