This map shows sites of extraction operations, sites of processing plants and mineral types for industrial mineral operations for Eastern Canada in 1970. The main map is accompanied by a supplementary map, at a scale of 1:30 000 000, that shows the location and annual capacities for cement plants as a percentage of the total national capacity for cement operations in 1970. Several graphs also accompany and show the value of production of cement by province for 1970, the value of the production of industrial minerals (except structural materials) for 1970, the value of the production of structural materials for 1970 and the volume of selected industrial minerals for the period 1886 to 1970.
