Despite the large amount of paleomagnetic, paleoclimatic, biogeographic, and tectonic data available, uncertainty still surrounds the paleotectonic evolution of Siberia and its proximity to other continents during the Ordovician to Silurian periods. Much of this uncertainty arises from the fact that paleomagnetic data cannot be adequately assessed.
However, recent Ordovician-Early Silurian paleomagnetic poles from the southern Siberian Platform (Lena River) show that Siberia was geographically inverted at low southerly latitudes during the Early Ordovician (Figure 1a). The Siberian plate then drifted slowly northward and across the equator at an average paleolatitudinal velocity of ˜5–8 cm yr−1. During Late Ordovician-Early Silurian time, its velocity increased northward.
