| SPATIAL-TEMPORARY CONNECTIONS OF THE EARLY CAMBRIAN SEA BASINS OF THE SIBERIA AND RUSSIA FAR EAST ON THE DATA OF DISTRIBUTION OF THE TUMULOSE ARCHAEOCYATHEANS |
L.G. Bondarenko, I.V. Kemkin Far East Geological Institute, FEBRAS, Vladivostok, 90022; e-mail: li_bond@mail.ru, kemkin@fegi.ru Based on the analysis of distribution of the tumulose archaeocyatheans complexes from the Early Cambrian cut-sections of the Siberia and Russia Far East, their settle centres are determined and the main directions of their migration are planned. It has allowed to reveal the temporary connections of the Early Cambrian sea basins, which were consistently established as a result of moving of the continental blocks of the broken supercontinent Rodinia. In view of the data on tumulose archaeocyatheans the disposition of separate continental blocks and adjacent structures for first three centuries of Early Cambrian are corrected. |
