Baikalides

The Baikalides are an ancient geological region in Asia that formed between approximately 850 and 570 million years ago along the southern edge of the Angaran platform. This period of formation involved the accretion of island arcs and microcontinents onto the Angaran platform, leaving behind remnants of old ocean floor.1

Following these collisions, rifting created new oceanic areas. By the early Paleozoic Era, subduction began beneath the enlarged continental nucleus, accumulating a significant prism of deep-sea sediments and oceanic crust fragments. This process contributed to the basement of mountain ranges like the Altai Mountains. Later Paleozoic events, including collisions during the Carboniferous Period, further shaped the Altaids, a complex tectonic collage in Asia.1
