u t Airborne geophysical data, used to produce this map, were supplied by the Geological Survey of Canada (GSC) - d y o Trans-Canada Highway . . . 50 n Northumberland Strait 50 80 a C 80 Geophysical Data Centre, 615 Booth St., Ottawa, Ontario K1A 0E9. These magnetic data were digitally acquired as part l 104 r u e o Pugwash b t Trunk Highway ...... of the high-resolution Antigonish (GSC Project #102), Guysborough (GSC Project #127), Musquodoboit (GSC Project c m i u P #184) and Parrsboro (GSC Project #189) surveys and the regional-scale St. Marys River Survey (GSC Project #152). C Collector Highway ...... The data, used to produce this map image, are the calculated second vertical derivative of the levelled and decorrugated Hard Road Surface ...... measured total field response. Vertical gradient data enhance near-surface magnetic sources at the expense of deeper Amherst features. Second vertical derivative data represent shallow (<500 m depth) sources. Zero value gradient PICTOU St. Georges Bay Lakes, Rivers, Coastline . . . contours also correlate closely with the vertical projection of magnetic contacts. The 24-bit colour map image was ISLAND County Boundary ...... produced with a 25 m pixel size. Shading was from the south at 35° above the horizon.
