Till, Indicator minerals, Surficial drill core
Till from drill core, NTS 73H/7 and 62F near Smeaton, Saskatchewan and the Virden area, Manitoba, 1992.
(requires an Internet connection)
Till was sampled over a kimberlite southwest of Smeaton, Saskatchewan. Just over 96 m of rotasonic drill core was collected and 40 till, 5 sand and 19 fine-grained sediment samples were taken from the drill core to study till in the third dimension. A summary of the work is published in GSC Bulletin 551.
In 1992, till was sampled from four drill holes in the Virden area near Reston, Beresford, Oak Lake and Kemnay, Manitoba as part of NATMAP. The data are part of a compilation, GSC Open File 5582.
<0.063 mm fraction by XRF for major and some minor elements; by INAA for 34 elements. <0.063 mm fraction of till and silt-clay samples and the 0.063-0.25 mm and <0.063 mm fractions of non-ferromagnetic heavy minerals by INAA for 35 elements. <0.063 mm fraction of till and silty-clay samples by AAS after a HF-HClO4-HNO3 digestion for selected trace elements.
Geochem Maps Available:

The geographic extent of the survey is defined by the following polygons:
Drill hole located 6.4 km west and 8 km south of the town of Smeaton, Saskatchewan in NTS 73H/7.
Covers part of NTS 62F (Virden) in southwest Manitoba. It is located just east of the MB-SK border and south of provincial Highway 1. It extends from just west of the town of Sinclair, northeast to Kemnay (approximately 95 km).
