Geodynamics and ore content of basite-ultrabasite complexes ofSiberian Platform southern framing rocks （Kodaro-Udokan and Muja zones of North Transbaikalye）

In southern framing of Siberian Platform, basite-ultrabasite intrusive complexes were forming over a long period of time (Early Proterozoic-Paleozoic Era) as a result of collisional and post-collisional processes. In Muja zone they formed mainly in island-arch geodynamic conditions, in Kodaro-Udokan zone-in continental. Most productive toward noble metals in Muja zones are basite-ultrabasites of the Dovyrensk complex‘, in Kodaro-Udokan basites of the Chiney complex. Gold in these formations has both mantle and crustal springs.
