Within the AK (Alag-Khadny), basement granite-gneiss rocks of the Zamtyn-Nuru crystalline complex (~950 Ma) are associated with metasedimentary rocks, including metapelites found at the southern margin of AK, which might represent a sedimentary cover of an Early Neoproterozoic rifted continental margin. The whole AK structure is tectonically overlain by volcanogenic-sedimentary and carbonate rocks of the Tsakhir-Uul Formation with Early Cambrian fauna. Eclogites were reported in AK as individual boudins (up to several hundred meters) in metasedimentary rocks and carbonates and are spatially associated with the spread of orthogneisses and metapelites.
