Abstract

The ferromagnetic minerals occurring in the Torridonian sandstones are described. Detrital grains of specularite often containing small inclusions of magnetite are present; the red haematitic cement is shown to be ferromagnetic. Possible origins of the natural remanent magnetization are discussed, and it is concluded that the evidence, especially the correlation of dispersion of the n.r.m. directions with the grain size of specimens, favours a depositional type of magnetization.
