Geomagnetic surveys at Skeleton Lake, Ontario
J. F. Clark · 1981
Magnetic and electrical surveys have been carried out at a near-circular structure which may be of meteoritic impact origin. This Paleozoic structure is located at Skeleton Lake, Ont. Data obtained by the multi-discipline approach have added to the available information and have provided some evidence in favour of meteoritic formation at this site. Contour maps showing total magnetic intensity over the feature exhibit low gradients of magnetic change typical of some meteoritic craters. Analysis of the data has helped evaluate the several geophysical surveying techniques employed as to their usefulness and feasibility in the on-going investigatiions of this feature, and the model obtained from the analysis indicates it to be a typical example of a 'simple' meteoritic crater, with a diameter of about 3.4 km and a depth to undisturbed bedrock of about 750 m.
