Popis: | The eastern boundary of the Siberian Craton was formed as a result of rifting that split the continent late in the Middle Paleozoic. The paleomagnetic data derived from the Middle Paleozoic kimberlites and basites that were formed in the zone of the dynamic effect of the Vilyui paleorift attest to the clockwise rotation of the Aldan terrane relative to the Angara–Anabar terrane during the post-Late Devonian time. The amount of rotation of the terranes increases gradually eastward and reaches 22° on the eastern flank of the Chara–Sinsk dyke belt. |
