Total magnetic force measurements over the North Macquarie Ridge and Solander Trough

T. Hatherton

Open publisher page 21 citations

Abstract

Abstract Associated with the North Macquarie Ridge is a positive total magnetic force anomaly, of 500–600 gammas amplitude and between 5 and 30 kilometres in width. The course of this anomaly is traced from Lat. 51° S, Long. 163° E, for a distance of 500 km north‐north‐east to Preservation Inlet, New Zealand, where measurements cease. A subsidiary positive anomaly appears to be associated with the west flank of the So lander Trough. The magnetic anomaly associated with the North Macquarie Ridge is related to other geophysical features of south‐west New Zealand.
