Survey Description

During the summer of 1992, in southeast Gaspé, heavy mineral preconcentrates were extracted from stream sediments by running stream gravels through a portable suction dredge.  A total of 314 samples were collected from as many sites in an area of 4300 km2, resulting in an average density of one sample per 13.5 km2.  The data are published in Geological Survey of Canada Open File 2788.

Quantities Analysed:

Heavy mineral preconcentrates were further processed using M.I. (S.G.=3.3g/cm3).  The percentage of each mineral species was visually estimated using a microscope.
