The Odd-twins magnetic anomaly and its possible relationship to the Humber Arm Klippe of Western Newfoundland, Canada

A distinctive twin-peaked magnetic anomaly known as Odd-twins magnetic anomaly has been traced for a distance of 65 km parallel to the coast of western Newfoundland about 10 km offshore. The magnetic anomaly is associated with a bathymetric high in some areas. It is interpreted as having been produc...

Description
Summary:A distinctive twin-peaked magnetic anomaly known as Odd-twins magnetic anomaly has been traced for a distance of 65 km parallel to the coast of western Newfoundland about 10 km offshore. The magnetic anomaly is associated with a bathymetric high in some areas. It is interpreted as having been produced by two parallel basic dikes (or sills) dipping 30–40° W. Such dikes would be near the base of the Long Point Formation and may delineate the western boundary of the Humber Arm Klippe.
