| 520 | |a"The thicknesses of 537 and 387 rhythmic couplets were measured along composite sequences of glacial Lake Ojibway glaciolacustrine deposits recovered in cores from Duparquet and Dufresnoy lakes, Quebec, respectively. The couplets span varve numbers 1137 to 1742 (Lac Duparquet) and 1189 to 1625 (Lac Dufresnoy) with respect to the Timiskaming varve series. Erosional unconformities (or disconformities) below v1484 cause 51 and 47 varves to be ‘missing’ in both the Duparquet and Dufresnoy varve records, respectively. Error in the varve numbering relative to the Timiskaming varve series is estimated to be ±2 varves. Varve thickness data for each lake are listed in separate digital spreadsheet files (.xlsx and .csv formats). Mosaic posters depict CT-Scanner radiograph images of each set of lake cores and show the interpreted varve numbering and the between-coring-site correlations of the varve couplets"--Abstract. |
