Abstract
The relationship between depositional grain orientation and current direction is discussed, and a method to assist in distinguishing between depositional and deformational magnetic fabrics is suggested. Magnetic fabric measurements from Middle and Upper Cambrian strata at St. Tudwal's Peninsula are presented. In the Maentwrog Beds (Upper Cambrian) a correspondence is found between the trend of the maximum magnetic susceptibility axes and the trend of the palaeocurrent as deduced from sole markings. In the Caered Mudstones and Flags (Middle Cambrian) the directions of maximum magnetic susceptibility are used to indicate palaeocurrent trends.
