Survey Description Till samples were collected from 31 boreholes up and down-ice and over the C14, B30, A4 and Diamond Lake kimberlite pipes in the Kirkland Lake area, northeastern Ontario. Till samples were also collected over and down-ice from the Buffonta kimberlite dyke. Soil (humus, B- and C–horizon) was collected over and down-ice from the C14 and Diamond Lake pipes and the Buffonta dyke. The data are published in Geological Survey of Canada Open File 3228. Data Description: Paper report. Quantities Analysed: <0.063 mm fraction by ICP-ES for 33 elements, by fire assay-ICP-AFS for Au, and by XRF for Nb, Sr, and Zr. <1.0 mm non-magnetic heavy mineral fraction by INAA for 34 elements. Other Analyses: Heavy mineral concentrate for kimberlite indicator minerals and gold and sulphide grains; matrix carbonate content; grain size. |
