| Abstract | As part of a reconnaissance sub-bottom acoustic profiling (SAP) survey, eleven SAP were collected from Lac Caste, Quebec, on July 10, 2014. The returns with the best penetration of the sub-bottom were
collected in the small bay in the southern area of the lake and along the immediate south and west sides of the main basin. There was no penetration of the sub-bottom over most of the central and eastern areas of the main basin. Three facies are
present within the SAP returns that represent lacustrine, glaciolacustrine and mass movement deposits. The profiles collected from Lac Caste 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. |
