| Abstract | (Summary)
High-resolution compressional (P-) and shear (S-) wave seismic reflection profiles were obtained using a vibratory source/landstreamer data acquisition system. The data were
collected during the summers of 2015 and 2016 along 5 profiles for a cumulative 48 line-km. The work was completed collaboratively with the Ontario Geological Survey (OGS) for a three-dimensional (3-D) mapping project encompassing the Niagara
Peninsula in support of the OGS groundwater geoscience initiative. The project's goal is to build a regional scale 3-D model of Quaternary deposits that form both regional and local aquifers and aquitards. The seismic profiles were collected to
provide improved knowledge of depth to bedrock and stratigraphic architecture of the Quaternary sediments to complement and enhance OGS data collection and modelling. |
| Summary | (Plain Language Summary, not published)
The Geological Survey of Canada acquired 48 line-km of seismic reflection data in July 2015 and July 2016. The shear wave seismic reflection profiles
provide images of the depth to bedrock, and of the structure of the overlying Quaternary sediments. Generally, the sediment structure is very complex exhibiting at least 3 major sequences. A number of bedrock troughs or buried valleys are imaged.
Three dome-shaped structures have been identified. The features are about ~250 and 200 m wide and have a thickness of ~35 m. One dome is ~1500 m wide and 30 m thick. Based on seismic reflection amplitudes diamicton and gravel cannot be uniquely
separated. One mound is intercepted by a borehole and consisted of dirty (slightly silty) sand and gravel. Based on the cored intercept, the dome would be interpreted as an esker. In many areas gravel and/or diamicton layers overlaying bedrock were
highlighted which likely have a significant influence on groundwater flow in the region and act as potential groundwater resources, particularly where associated with bedrock channels. |
