AbstractAs part of a reconnaissance sub-bottom acoustic profiling (SAP) survey, 32 SAP were collected from Lac Flavrian, Quebec, on July 14, 2014. The quality of the returns from Lac Flavrian are generally poor with there being little to no penetration of the sub-bottom along most of the profiles. Despite this, three depositional facies can be identified within the lake basin returns that represent lacustrine, glaciolacustrine and mass movement deposits.
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.
