Artyushkov E.V.; Baer M.A.; Chekhovich P.A. (2000)

Subsidence of continental crust in fold belts is commonly interpreted as related to extension or elastic flexure of the lithosphere near convergent plate boundaries. In the Late Cambrian - Early Ordovician, relative extension ...

EARLY PALEOZOIC PALEOGEOGRAPHY OF LAURENTIA AND WESTERN GONDWANA: EVIDENCE FROM TECTONIC SUBSIDENCE ANALYSIS: REPLY

Williams K.E. (1998)

A number of terranes were present in the early Paleozoic ocean between Laurentia and Gondwana following rifting. The precise location of these microcontinents and island arcs is unclear. We present tectonic subsidence ...

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 ...

EARLY PLEISTOCENE FAUNAS OF SMALL MAMMALS IN EASTERN EUROPE

Markova A.K. (1999)

Materials from many lower Pleistocene localities of small mammal remains elucidate principal stages of the fauna evolution in eastern Europe and enable the biostratigraphic subdivision of host deposits on the basis of ...

EARLY PRECAMBRIAN MAFIC ROCKS OF THE FENNOSCANDIAN SHIELD AS A REFLECTION OF PLUME MAGMATISM: GEOCHEMICAL TYPES AND FORMATION STAGES

Arestova N.A.; Lobach-Zhuchenko S.B.; Chekulaev V.P.; Gus'kova E.G. (2003)

The analysis of radiometric ages of Early Precambrian basites of the Fennoscandian shield, from the most ancient ones, > 3.1 Ga, to 2.40 Ga, resolves five age groups of the basites. Each of these stages is shown to time ...

EARLY SILURIAN SEA-LEVEL CHANGES

Loydell D.K. (1998)

Global sea-level fluctuated markedly during the early Silurian, probably as a result of the waxing and waning of ice-sheets in the South American portion of Gondwana. The highest sea-levels of the Silurian are recorded by ...
