Abstract
The new microwave palaeointensity technique has been used to investigate sa mples from the Martian meteorite Nakhla. This technique is a promising new way to obtain absolute palaeointensity information regarding the ancient Ma rtian magnetic field as recorded by the Martian meteorites. Assuming that a part of the magnetic remanence is of thermal origin and originating on Mar s the two samples studied yield estimates of 4 muT for the Martian magnetic field at 1.35 Ga.
