A reliable Early Cambrian (c. 535 Ma) and a preliminary Late Cambrian (c. 500 Ma) palaeomagnetic pole from Baltica (Sweden) overlap within uncertainty, and they are also broadly compatible with Vendian (c. 583 Ma) palaeomagnetic data. Apparent polar wander for Baltica amounts to less than 25° between 583 and 500 Ma and, therefore, negates recent speculations that the Earth tipped 90° during the Early Cambrian (true polar wander). Throughout Vendian and Cambrian times, Baltica lay at southerly…

Baltica and the Cadomian orogen in the Ediacaran–Cambrian: a perspective from SE Poland

In the supercontinent of Rodinia, Baltica occurred next to Amazonia, then the two drifted away when Rodinia broke up. By the end of the Neoproterozoic, Baltica became an independent continent. At

New Late Vendian palaeogeography of Baltica and the TESZ

New palaeomagnetic poles obtained from the Vendian tuffs and basalts of western Ukraine indicate the necessity of a substantial revision of the Late Vendian-Early Cambrian palaeogeography of the

Late Neoproterozoic and Early Cambrian palaeogeography: models and problems

Abstract We present two alternative sets of global palaeogeographical reconstructions for the time interval 615–530 Ma using competing high and low-latitude palaeomagnetic data subsets for Laurentia

Late Neoproterozoic to Early Palaeozoic palaoegeography of the Holy Cross Mountains (Central Europe): an integrated approach

Study of geochemistry, examination of isotope ages of detrital minerals, palaeomagnetic analysis, and a study of the trilobites were performed to provide constraints on the palaeogeographical

A palaeomagnetic and palaeobiogeographical perspective on latest Neoproterozoic and early Cambrian tectonic events

During the latest Neoproterozoic to Mid-Cambrian time (580–505 Ma ago), the Earth underwent significant changes in palaeogeography that included rifting of a possible supercontinent and the near

Accretion of first Gondwana-derived terranes at the margin of Baltica

Abstract In central Europe, three crustal units, i.e. the Małopolska, the Łysogóry and the Bruno-Silesia, can be recognized by basement data, faunas and provenance of clastic material in the Cambrian

Early Cambrian location and affinities of the Brunovistulian terrane (Central Europe) in the light of palaeomagnetic data

The Brunovistulian was one of the first tectonic units of Central Europe to be defined as a ‘terrane’. In spite of extensive studies, the Early Palaeozoic palaeogeographical position and provenance
