Abstract

This data set consists of 20 TIFF images, 20 JPEG images and 20 PDF Open File Maps of airborne magnetic total field for each of 20 1:50 000 NTS sheets which cover most of northern mainland Nova Scotia.

The data used to generate these images and maps were supplied by the Geological Survey of Canada - Geophysical Data Centre, 615 Booth St., Ottawa, Ontario, K1A 0E9, and the Radiation Geophysics Division, 601 Booth St., Ottawa, Ontario, K1A 0E8. The original magnetic data were acquired as part of: Project #102 "Antigonish Survey", Project #127 "Guysborough Survey", Project #184 "Musquodoboit Survey", Project #189 "Parrsboro Survey" and Project #152 "St. Mary's River Survey". Map coverage was locally augmented by older vintage GSC analogue data. The MAGNETIC TOTAL FIELD images were derived from the levelled and decorrugated measured magnetic total field. The 24-bit colour images were divided out into individual 1:50 000 NTS sheets and were produced with a 10m pixel size.

Each of the individual 1:50 000 NTS sheets is coloured to optimize the features on that sheet and a separate colour bar is provided for each sheet. Shading was from the south at 35° above the horizon. For complete details an Open File Report will be forthcoming from M. S. King later in 2004.

The images were produced by contractor M. S. King using funds provided under the Natural Resources Canada and Nova Scotia Department of Natural Resources joint project 'Mapping, Mineral and Energy Resource Evaluation, Central Nova Scotia', part of Natural Resources Canada's Targeted Geoscience Initiative (TGI-2) 2003-2005.
