Data Description |
|
Abstract: |
This digital data set consists of a single color TIFF file, where high resolution aeromagnetic surveys exist over the western Meguma Terrane. The TIFF represents the second vertical derivative of the vertical gradient magnetic data, with most of the original data being collected by aeromagnetic surveys flown by the Geological Survey of Canada (GSC). The data has been gridded to a 50 m cell size. These images were derived from some of the same aeromagnetic surveys as used to create the DP ME 8 and 372 products. This images covers that same area as DP ME 372, but incorporates all the data into a single image, although at a higher resolution. This work was done by M. S. King under contract to the Mineral Resources Branch (MRB). |
|
Purpose: |
These images are designed to highlight structure and stratigraphy within the Meguma Group. |
