Survey Description

During the summer of 1985 in the region of Estrie-Beauce, Quebec, heavy mineral preconcentrates were extracted from stream sediments by running about 250 kg of stream gravels through a portable suction dredge.  A total of 703 samples were collected from as many sites resulting in an average density of one sample per 11.8 km2 over the 8300 km2 study area.  The data are published in Geological Survey of Canada Open File 1332.
