Survey Description

In 1989, heavy mineral preconcentrates and stream sediments were collected at 310 sites in Quebec’s Eastern Townships (Estrie-Beauce) east of the Chaudière River.  The area sampled was 3225 km2 producing an average sample density of 1 sample per 10.4 km2.  Heavy mineral preconcentrates were extracted from stream sediments by running about 250 kg of stream gravels through a portable suction dredge.  The collection of stream sediments represents a departure from the normal practice employed previously in Estrie-Beauce of collecting and analyzing only heavy minerals.  The data are published in Geological Survey of Canada Open File 2601.
