Survey Description

During the summer of 1984, heavy mineral preconcentrates were extracted from stream sediments by running stream gravels through a portable suction dredge in the Estrie area, Quebec.  A total of 312 sites were sampled over an area of approximately 4500 km2. The data are published in Geological Survey of Canada Open File 1145.
