Neoproterozoic Magmatism

The article presents new age data on the ‘key’ Early Paleozoic igneous complexes located in the central part of the Bureya continental massif of the Central Asian Fold Belt. Porphyroblastic quartz monzonites of the Kivili complex are dated to 453±2 Ma. The age of gneissic granites of the Sularin complex is ~481 Ma. The Sm-Nd isotope stu­dies show that Late Ordovician quartz monzonites were formed mainly from crustal sources with Paleoproterozoic Nd model isotopic ages. Both ancient (Paleoproterozoic?) and younger sources were involved in the formation of Cambrian granites. Our data, as well as previously published materials, suggest several stages of the Early Paleozoic magmatism in the evolution of the Bureya continental massif: ~541, ~504–500, ~487, ~474 and ~453 Ma. Early Paleozoic magmatism developed under a similar scenario in the Jiamusi continental massif. In addition to the synchronism of Neoproterozoic magmatism within these continental massifs, this feature testifies to their common geological history.

AbstractIt is suggested that the ancestors of the Baikalian amphipods originated in Central Asian brackish-water basins in the Late Mesozoic, while the geological history of the Baikalian rift valley and subsequent Cenozoic glaciations influenced the evolution of the group. Il est suggere que les ancetres des amphipodes du lac Baikal ont leur origine dans les bassins d'eau saumatre d'Asie centrale a la fin du Mesozoique, bien que l'histoire geologique de la fosse du Baikal et les glaciations cenozoiques subsequentes aient influe sur l'evolution du groupe.
