Survey Description

117 till samples collected in the Winter Lake area (NTS 86A), Northwest Territories and Nunavut in 1993. Data published in GSC Open Files 2908 and 3206.

Data Description: Paper report; text and data on diskette (WP, ASCII, Excel 3.0) for GSC OF 2908. Paper report; geochemical data and illustrations on diskette (Excel 3.0, ASCII, and WP) for GSC OF 3206.

Quantities Analysed: <0.002 mm and <0.063 mm fractions of till by ICP-AES after aqua regia (3HCl:1HNO3) for 28 elements; <0.063 mm fraction by INAA for 35 elements for GSC OF 2908. <0.002 mm fraction by ICP-AES (Chemex) after nitric-aqua regia digestion for 29 elements; <0.063 mm by INAA for 35 elements for GSC OF 3206.

Geochem Plots Available: Proportional dot maps showing dispersal of elements in the <0.002 mm and <0.063 mm fractions for GSC OF 3206.

Other Analyses: Heavy mineral concentrate for kimberlite indicator mineral analysis (47 samples) for GSC OF 2908. Heavy mineral concentrate for gold grain counts for GSC OF 3206.

Project History

1992-1996 NATMAP Slave Province Project, Quaternary geology component, 1992-1993.
  As part of the Slave Province NATMAP, Quaternary field mapping and till sampling were carried out in 1993, following a brief reconnaissance survey in 1992. The till samples were taken to characterize the composition of the glacial materials and to establish regional background values of various elements. The data were published in GSC Open Files 2867 and 3120 (final report) for NTS 76C; in GSC Open Files 2868 and 3205 (NTS 76D), GSC Open Files 2908 and 3206 (NTS 86A).
