Title: baffinmag.tif Geospatial_Data_Presentation_Form: remote-sensing image Online_Linkage: \\W5-OTT-H000947\Projects\of5116\digital_release\data\geophysics\Magnetics\baffinmag.tif Description: Abstract: This image shows the colour-coded map of the residual magnetic field. The image has a pixel size of 42m. The area north of 65N consists of digitized data resulting from two surveys flown between 1966 and 1974. A flight-line spacing of 800 m and flight altitude of 305 m above ground were used in both cases. South of 65N, data were acquired digitally in three surveys flown between 1996 and 1997. A flight-line spacing of 800 m and flight altitude of 150 m above ground were used for these surveys. The International Geomagnetic Reference Field for the date and altitude of each survey has been removed. Purpose: Trends of magnetic anomalies reflect geological variations. Patterns of anomalies may reflect structural regimes as well as lithological variations. Since magnetic anomalies are mostly caused by variations in magnetite content, the relation between magnetic field and lithology is complicated since lithology is based mainly on silicate mineralogy. However, mapping the texture or patterns of anomalies, their truncation and extent provides valuable structural information. Additionally, the shape of areas with similar magnetic texture can also indicate lithology.
