Magnetic anisotropy, particularly in the form of AMS (anisotropy of magnetic susceptibility) has been used widely for petrofabric and structural studies. It is still a popular technique in wide range of applications due to its high sensitivity as well as for its cost and time effectiveness. The technique has also been modified into various methods termed collectively as anisotropy of magnetic remanence (ARM), while the remanence could be either anhysteretic or isothermal remanences. Notable use of these methods include compaction study in sediment as well as study of flow in lavas. The variation of magnetic anisotropy methods will be compared and reviewed. New findings on the nature of magnetic anisotropy in soft and hard rocks will also be presented. This includes the the incorporation of pore distribution analyses into magnetic anisotropy studies.
