New paleomagnetic data on baltica based on upper ediacaran deposits on the western slope of the Middle Urals

The latest concepts about the Earth’s paleogeography for the period of 700–500 million years are quite contradictory. Reliable paleomagnetic data are quite scarce for the Ediacaran-Cambrian of the majority of continental plates, which means that making any reliable global paleogeographic and paleotectonic reconstructions is impossible. According to various authors, Baltica within this time, for example, could have been located at any latitudes from the South Pole to the equator. Making correct reconstructions requires new paleomagnetic data; however, almost all objects that are applicable for such studies within Baltica have already been studied. A possible solution is to study the deformed margins of the plate, in particular, the western megazone of the Middle Urals, where the lower and upper Ediacaran volcanogenic-sedimentary and sedimentary sections are known within the Kvarkushsko-Kamennogorskii anticlinorium [1, 2] (Fig. 1). This paper presents the first paleomagnetic results obtained for the sedimentary rocks of the Upper Ediacaran Chernokamenskaya suite. They are consistent with the group of six poles of the same age [3–7], by which Baltica was located at the subequatorial latitudes at the end of the Educarian.
