Brunhes–Matuyama paleomagnetism in three lava sections in Iceland
This paper reviews previous field research on the paleomagnetism of volcanics in Iceland at localities whose age is presumed to span the Brunhes–Matuyama chron boundary. Additional mapping and laboratory measurements are presented from three localities of late Quaternary reverse-to-normal transitions. At two, Tjornes in north Iceland and Eyjafjoll in south Iceland, the identity of the transition is confirmed by K–Ar dating. At Tjornes and at Ingolfsfjall in southwest Iceland, short-period variations of the paleomagnetic field are demonstrated to be useful in stratigraphic mapping.
