The Olkhon composite terrane includes Olkhon Island and the adjacent landmass of the western Lake Baikal shore. It belongs to the Early Paleozoic Baikal collisional belt, delineating the southern periphery of the Siberian craton together with the Sludyanka and Kitoikin terranes. The Olkhon terrane is an intricate collage of 500 Ma and 460 Ma genetically different igneous and metamorphic complexes. The terrane is composed of two major units: (i) Krestovsky subterrane composed of gabbro (over 50% of total rock volume) and metamorphic rocks (marble and amphibolite) and (ii) a package of tectonic units composed mainly by gneisses with lesser amounts of marble, amphibolite, and quartzite, as well as gabbro and granite intrusions and numerous granitic, pegmatitic, and aplitic veins. The formation of the terrane was interpreted as resulting from successive events of thrusting, doming, and strike–slip faulting, with syntectonic high-temperature metamorphism and intrusions of mafic and granitic magmas. The well-documented rocks produced by the three major tectonic events originated in the Early Paleozoic as a result of microcontinent–island arcs and microcontinent–continent collisions. It was the extensive strike–slip faulting that controlled the general tectonic framework of the terrane, consisting of multiple blocks and shear zones that differ in structure, morphology, and composition.
