contents During drilling at Sites 759, 760, and 761 of Leg 122 (Exmouth Plateau, northwest Australia), a thick section of Upper Triassic sediments was recovered. Paleomagnetic analyses were made on 398 samples from Holes 759B, 760A, 760B, and 761C. Progressive thermal demagnetization, alternating field demagnetization, or mixed treatment removed an initial unstable component and isolated a characteristic remanent magnetization which is of normal or reversed polarity. The magnetostratigraphic results allow us to propose a magnetic polarity sequence which extends from the upper Carnian to lower Rhaetian. This sequence reveals many more reversals than previously suggested from paleomagnetic studies. The magnetostratigraphic data also allow us to suggest correlations between Sites 759 and 760.
