Magnetic Measurements Over Darnley Bay, N.W.T.

Five high level, 3-component, magnetic profiles outline a large magnetic anomaly approximately coincident with the previously observed, 130 mgal, positive gravity anomaly. Three-dimensional interpretations of the magnetic data establish the major dimensions of the source body but do not distinguish...

Description
Summary:Five high level, 3-component, magnetic profiles outline a large magnetic anomaly approximately coincident with the previously observed, 130 mgal, positive gravity anomaly. Three-dimensional interpretations of the magnetic data establish the major dimensions of the source body but do not distinguish between a normal and inverted conical shape. Directions of magnetization derived from the interpretations suggest that the body is geologically related to the Precambrian Franklin Diabases.
