During the main episode of the Chinese Altaides (Early Carboniferous), progressive metamorphic zones, migmatite zones and migmatitic granitic gneiss fileds developed around and in the regional thermodynamic anomalies in the orogenic belt and constitute a series of thermal domes and gneiss domes.

TIMS U-Pb zircon ages of Fuyun post-orogenic linear granite plutons on the southern margin of Altay orogenic belt and their implications;

The Altay orogenic belt,in Xinjiang,China was formed mainly during late Devonian to early Permian and was mainly a thrust-nappe-detachment orogenesis.

Middle Devonian picrites of the south margin of Altay orogenic belt occur in the lower part of the Beitashan Fm.

The Altai orogeny, as one of notable crustal accretion areas, is famous for its abundant mineral deposits.

Phase equilibrium of low-pressure metamorphism in the Altaides,Xinjiang;

After largescale deep-level thrust nappe in Hercynian,the post-orogenic extension occurred in the southern boundary of Altaides,and formed Kelan,Kuerti,Maizi,Areletuobie and Sulubayi metamorphic core complexes.

The continental collision between Siberian and Kazakhstan-Junggar in Early Carboniferous shaped the large-scale dual thrust-nappe structures in the Altay orogen, NW China.

In the study a systematic finite strain measurement was made on a 50 km-wide section across the Altay orogen in the Fuyun region, with methods such as the dip-isogon of folds, three-dimensional strain of pebbles and S-C angle.
