Till Saskatchewan 1992

Till from drill core, NTS 73H/7, near Smeaton, Saskatchewan, 1992.  


Geological Survey of Canada, Terrain Sciences Division

Survey Description

Till sampled over a kimberlite southwest of Smeaton, Saskatchewan. 96.3m of rotasonic drill core was collected and 40 till, 5 sand and 19 fine-grained sediment samples were taken from the drill core. Data published in GSC Bulletin 551.

Data Description: Paper report.

Quantities Analysed: <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 Plots Available: Plots of selected elements in till sequence.

Other Analyses: HMC for heavy mineral point counts, especially kimberlite indicator minerals; geochemical analysis of selected heavy mineral grains; pebble lithologies (9-16 mm); carbonate (<0.063 mm fraction (Chittick)).

Project History

1991-1995 Canadian Prairie soil and till ultra-low density survey, 1991 and 1992.
  The objective of this project is to provide geochemical and mineralogical data on the regional variability of soils and glacial drift to assist in the exploration for kimberlites, lamproites and gold paleo-placers in the southern Prairies. The project was carried out over two years. The first year involved 2 orientation traverses to collect soil and till samples to determine what procedures (field and analytical) should be used in the full 1992 grid survey covering the same area. In 1992, a drill core was taken over a kimberlite to study till in the third dimension. The 1991 data are published in GSC Open File 2685 and the 1992 till data are published in GSC Open File 2745. The drill core study is published in GSC Bulletin 551.
