Magnetic fabric research on the emplacement of the Taimyr fold-belt is still absent. Therefore, we have performed magnetic fabric studies on samples collected from 23 sites from mafic igneous rocks (75°N, 100°E) in South Taimyr. This study indicate

A paleomagnetic investigation of the Alno carbonatite complex dikes was undertaken in an attempt to refine the apparent polar wander path for Baltica. The currently available paleomagnetic database for the Ediacaran–Cambrian segments of the Baltica

SUMMARY Palaeomagnetic data for Baltica in the Late Precambrian are highly ambiguous, and have therefore, given rise to different interpretations concerning the need to explain Varangerian glaciations through snowball Earth conditions. We present new

SUMMARY New palaeomagnetic results and 40 Ar/ 39 Ar ages from mafic sills and extrusive rocks from the South Taimyr igneous complex (75 ◦ N, 100 ◦ E) document late Middle‐Early Late Triassic igneous activity in Arctic Siberia. The palaeomagneti

Late Carboniferous–Early Tertiary apparent polar wander (APW) paths (300–40 Ma) for North America and Europe have been tested in various reconstructions. These paths demonstrate that the 500 fathom Bullard et al. fit is excellent from Late Carbon

The post-Sveconorwegian Hunnedalen dyke swarm intrudes the high-grade Proterozoic gneiss complex of SW Norway. The dykes yield a Sm‐Nd whole-rock-mineral date of 855 " 59 Ma and a 40 Ar= 39 Ar biotite plateau date of 848 " 27 Ma (2! ). The consiste

SUMMARY 40Ar/39Ar whole-rock and alkali feldspar ages demonstrate that dioritic to monzonitic dykes from Boverbru and Lunner belong to the youngest recorded magmatic activity in the Oslo Rift region, southeast Norway. These dykes represent the termin

Coast-parallel dykes in SW Norway, primarily of Permo-Triassic age, have been linked regionally to the early tectonic evolution of the Norwegian continental shelf. We demonstrate from palaeomagnetic data (mean declination = 206.1°, inclination = —

During the Neoproterozoic and Palaeozoic the two continents of Baltica and Laurentia witnessed the break-up of one supercontinent, Rodinia, and the formation of another, but less long-lived, Pangea. Baltica and Laurentia played central roles in a tec
