This digital data release contains the results of geochemical and grain size analyses conducted on drillcore samples of glacial sediments from two wells in the Muskeg Mountain area north of Fort McMurray in northeastern Alberta. The samples were analyzed to help understand the differences in geophysical log responses of glacigenic sequences and to further characterize the thick package of sediment resting on the bedrock topography surface in the area.
Geochemical and particle size analyses have been successfully used to differentiate till units in core which can then aid in correlating with geophysical responses of similar sediments in neighbouring wells, thus allowing units to be mapped over a larger area. Cores were selected to be examined based on the length and quality of recovery. Geochemical analysis was completed on the silt and clay fraction of core samples using inductively coupled plasma–mass spectrometry (ICP-MS) and inductively coupled plasma–emission spectrometry (ICP-ES), and on the intact core (i.e., whole sediment) using a handheld X-ray fluorescence (XRF) analyzer.
