BALTICA. A SYNOPSIS OF VENDIAN-PERMIAN PALAEOMAGNETIC DATA AND THEIR PALAEOTECTONIC IMPLICATIONS

Torsvik T.H.; Smethurst M.A.; Trench A.; Van der Voo R.; Abrahamsen N.; Halvorsen E. (1992)

In light of recent additions to the Palaeozoic palaeo-magnetic data-base, particularly for the Ordovician era, a revised apparent polar wander (APW) path for Baltica has been constructed following a rigorous synthesis of ...
CONTINENTAL BREAK-UP AND COLLISION IN THE NEOPROTEROZOIC AND PALAEOZOIC - A TALE OF BALTICA AND LAURENTIA

Torsvik T.H.; Smethurst M.A.; Sturt B.A.; Meert J.G.; Van der Voo R.; Walderhaug H.J.; McKerrow W.S.; Brasier M.D. (1996)

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 ...
EARLY PALEOZOIC PALEOMAGNETISM OF EAST KAZAKHSTAN: IMPLICATIONS FOR PALEOLATITUDINAL DRIFT OF TECTONIC ELEMENTS WITHIN THE URAL-MONGOL BELT

Collins A.Q.; Bazhenov M.L.; Degtyarev K.E.; Levashova N.M.; Van der Voo R. (2003)

Conflicting paleogeographic reconstructions of the Ural–Mongol fold belt have been developed over the past decade; very few of them, however, have been based on paleomagnetic data, which still remain scarce. The Chingiz ...
MIDDLE PALEOZOIC PALEOMAGNETISM OF EAST KAZAKHSTAN: POST-MIDDLE DEVONIAN ROTATIONS IN A LARGE-SCALE OROCLINE IN THE CENTRAL URAL-MONGOL BELT

Levashova N.M.; Degtyarev K.E.; Bazhenov M.L.; Collins A.Q.; Van der Voo R. (2003)

In order to test different hypotheses concerning the Paleozoic evolution of the Ural–Mongol belt (UMB) and the amalgamation of Eurasia, we studied Middle Devonian basalts from two localities (11 sites) and Lower Silurian ...
PALEOZOIC NORTHWARD DRIFT OF THE NORTH TIEN SHAN (CENTRAL ASIA) AS REVEALED BY ORDOVICIAN AND CARBONIFEROUS PALEOMAGNETISM

Bazhenov M.L.; Degtyarev K.E.; Levashova N.M.; Collins A.Q.; Van der Voo R.; Mikolaichuk A.V.; Pavlov V.E. (2003)

Three new Middle–Late Ordovician and two new Early Carboniferous paleomagnetic poles have been obtained from the North Tien Shan Zone (NTZ) of the Ural–Mongol belt in Kyrgyzstan and Kazakhstan. Paleolatitudes for the ...
PERMIAN PALAEOMAGNETISM OF EAST KAZAKHSTAN AND THE AMALGAMATION OF EURASIA

Levashova N.M.; Degtyarev K.E.; Bazhenov M.L.; Collins A.Q.; Van der Voo R. (2003)

Most of Kazakhstan belongs to the Ural-Mongol belt, the tectonic evolution of which is poorly understood as demonstrated by disparate tectonic models suggested thus far. We undertook a palaeomagnetic study of Upper Permian ...
TEM STUDY OF THE ALTERATION OF INTERSTITIAL GLASS IN MORB BY INORGANIC PROCESSES

Zhou W.; Peacor D.R.; Alt J.C.; Van der Voo R.; Kao L.S. (2001)

Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) observations on a suite of mid-ocean ridge basalts (MORB) reveal abundant interstitial glass, which differs in occurrence and composition from ...
TOO-LOW MAGNETIC INCLINATIONS IN CENTRAL ASIA: AN INDICATION OF A LONG-TERM TERTIARY NON-DIPOLE FIELD?

Si J.; Van der Voo R. (2001)

Observed Tertiary palaeolatitudes in central Asia are more southerly (by about 1600 km on average) than those predicted from the Eurasian reference palaeopoles. Subsequent northward displacements of the central Asian ...
TRUE POLAR WANDER DURING THE PERMO-TRIASSIC

Marcano M.C.; Van der Voo R.; Mac Niocaill C. (1999)

The apparent polar wander path for the Pangea supercontinent is about 35° long for the interval of 295-205Ma, which means that in that interval Pangea rotated over an angle of 35° with respect to the rotation axis about ...
