Open File NFLD/3402 comprises results from a recent high-resolution airborne magnetic radiometric and VLF-EM survey of the Burin Peninsula region, Newfoundland. The survey area has been split into southwest (SW) and northeast (NE) map portions to enable presentation at a scale of 1:100 000. Results are presented as 4 magnetic, 16 radiometric and 6 VLF-EM full-colour maps in pdf format.
