...V.A. Anan’ev; O.P. Polyansky; G.G. Lepezin; V.V. Reverdatto The Tongulak metamorphic complex lies in southeastern Gorny Altai, in the Bashkaus-Kubadru interfluve. Four zones have been recognized in its composition: chloritic (on the periphery), cordieritic, sillimanitic, and staurolite-free...

... structure is not uniform. The central part is occupied by a lens-like northwesterly trending block (the Kurai block) bordered in the west and east by intricately built wrench fault zones. Along these zones, the block borders the Kubadru and Bashkaus massifs which are isometric neotectonically uplifted...
