AbstractAs part of a reconnaissance sub-bottom acoustic profiling (SAP) survey, 22 SAP were collected from Lac Kinojévis, Quebec, on July 11, 2014. The eight profiles with the best penetration were located in the southeastern, narrower area of the lake. Two depositional facies can be identified within the SAP returns that represent lacustrine-fluvial and glaciolacustrine deposits. No obvious mass movement deposits are present in the profiles.
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.
