Abstract
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. The metamorphic zoning is symmetrical, with a general width of 13-15 km. Conditions of metamorphism are estimated to have been 500-700
