Abstract
Total magnetic force anomalies across Norfolk Ridge are caused by basaltic extrusions which are normally magnetised with an average magnetisation of 1.4 × 10−2 e.m.u. These rocks have a minimum thickness of about 1.–2.0 km in the central part of the ridge, and are covered by a thin layer of non-magnetic deposits.
