Geological Survey of Canada, Terrain Sciences Division

Survey Description

520 till samples were collected in the Clyde Forks – Westport area, Ontario in 1986-88. The data are published in GSC Open File 2274. This open file also republishes data for 400 archived samples from NTS 31C/10 (Tichborne) and 31F/1 (Carleton Place) previously published in GSC Open File 947. Some data from OF 2274 has been included in GSC Open File 3175, a digital compilation of data from OFs 1792, 947 and part of 2274. Some of the data from OF 2274 have also been released as part of a big Ontario-Quebec summary and interpretation in GSC Bulletin 463.

Data Description: Paper report; digital data on diskette.

Quantities Analysed: <0.002 mm fraction by AAS after hot nitric-hydrochloric digestion for 12 elements; by colourimetry for As, and by fluorometry for U. <0.063 mm fraction by fire assay/AAS after hot nitric-hydrochloric digestion for Au, Pt, and Pd.

Geochem Plots Available: Proportional symbol maps show dispersal of selected elements.

Other Analyses: Pebble lithologies; grain size; carbonate (<0.063 mm by LECO).

Project History

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 Data from parts of Open File 2274 have been superseded by GSC Open File 3175, a digital release, which also includes data from OFs 1792 and 947.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.
