How did collisions between Europe and Asia form the Uralian orogenic belt?

The Uralian orogenic belt was formed through the closure of the Uralian Sea. This process was driven by the eastward subduction of the sea floor and the subsequent collision of island arcs and small continental blocks with the east European continent.1

During this collision, a major thrust transported slabs of the Uralian ocean floor westward as ophiolites. This tectonic activity also led to the creation of oil-bearing foreland basins along the western side of the Urals. The final compression of the mountain system occurred during the Permian Period and the Early Triassic Epoch, followed by post-orogenic extensional collapse, which facilitated the uplift and exposure of high-pressure rocks.1
