Survey Description


During the summer of 1973, a lithogeochemical survey of the acid porphyry rocks of the Proterozoic Bear province was undertaken.  Regional and detailed sampling were carried out.  Approximately 2200 rock samples were collected.  The data are published in Geological Survey of Canada Open File 2257.
