Geological Survey of Canada, Terrain Sciences Division

Survey Description

Till samples were taken on the Frontenac Arch and surrounding areas in southeastern Ontario in 1980-1981. The data are published in GSC Open File 947. This open file has been superseded by a digital release, GSC Open File 3175 which also includes data from OFs 1792 and 2274. The data from OF 947 have also been released as part of a big Ontario-Quebec summary and interpretation in GSC Bulletin 463.

Data Description: Paper report and data lists; sample location map.

Quantities Analysed: <0.002 mm fraction of till by AAS after HNO3-HCl leach for 12 elements (including Hg); by colorimetric method for As; by fluorometric method for U.

Other Analyses: Grain size (<2 mm fraction); carbonate (<0.063 mm by LECO).

Project History

1980-1988 Frontenac Arch, southeastern Ontario and Muskoka area, Ontario till sampling surveys carried out in 1980-1985.
  A program of systematic overburden sampling was initiated on the Frontenac Arch and adjacent areas of southeastern Ontario in 1980. It was extended to the Muskoka, Ontario region in 1984. The project was designed to quantify regional variation in drift composition in order to provide baseline data for use in assessing the sensitivity of the terrain to the effects of acid rain. Much of the information obtained from the study can also be used as an aid to mineral exploration in the area. The data were published in GSC Open Files 947 (Frontenac Arch, southeastern Ontario) and 1792 (Muskoka). Both open files have been superseded by GSC Open File 3175 (data are digital) which also includes data from part of 2274. The data from OFs 947 and 1792 are also published as part of a big Ontario-Quebec summary and interpretation in GSC Bulletin 463.

1986-1990 Clyde Forks – Westport, Ontario till sampling survey carried out in 1986 and 1988.
  In 1986 a program of surficial geologic mapping and systematic glacial sediment sampling was undertaken in eastern Ontario, in the Clyde Forks – Westport area. The project was designed to quantify regional variation in drift composition in order to provide baseline data for use in assessing the sensitivity of the terrain to the effects of acid rain. Much of the information obtained from the study can also be used as an aid to mineral exploration in the area. The data are published in GSC Open File 2274. The OF includes new data for samples previously published in GSC Open File 947. Data from parts of Open File 2274 have been superseded by GSC Open File 3175, a digital release, which also includes data from OFs 1792 and 947. Some of the data from OF 2274 are also published as part of a big Ontario-Quebec summary and interpretation in GSC Bulletin 463.
