| Abstract | A methodology is being developed to identify lineaments in aeromagnetic and digital elevation model (DEM) data that will assist in locating brittle faults. The method focuses on magnetic contacts and
dykes in aeromagnetic data and local curvature analysis in a DEM. The current approach combines several techniques including multi-scale detection, curvature analysis, image thresholding and mathematical morphology. The test area is the northern
Melville Peninsula (Canadian Arctic) where a diamond prospect is possibly associated with brittle faults. The present paper reports on the methodology being developed and some preliminary results. |
