Abstract:
The crystalline basement of the Siberian Craton is exposed as fragments in the Sharyzhalgai inlier, which is separated by the Main Sayan fault from Paleozoic rocks of the Slyudyanka crystalline complex and is bounded by the ~70-km-long Baikal coastline from the Settlement of Kultuk to port of Lake Baikal. The geological boundary between Sharyzhalgai and surrounding Caledonides is at the Lake Baikal floor. The spatial association of Archean and Proterozoic rocks with Paleozoides has repeatedly inspired researchers to search for traces of endogenous influence of the Paleozoic framing on the rocks and basement of the platform.
