Abstract: We present 26 reliable Precambrian paleomagnetic poles for Siberian Craton. Their analysis together with geological data implies low to middle latitudinal positions of the craton at 1870–760 Ma. Geological data suggest that the craton has been completely assembled at c.1860 Ma and that at 1800–1100 Ma the western, northern, and eastern margins of the craton faced oceans, but the southern margin has been in close proximity or connection with another continent. Our analysis of coeval paleomagnetically constrained locations of Siberia and Laurentia at c.1735 Ma, 1480 Ma, and 1380 Ma supports their proximity, but not a close contact. Based on recent geological data we suggest that the Yantze Craton has been located between southern Siberia and northern Laurentia at those times. The analysis of roughly coeval 1100–1000-Ma Apparent Polar Wander Paths for Siberia and Laurentia supports their proximity, but due to age uncertainties a “tight” and “loose” connection between two cratons cannot be distinguished.
