Based on detailed geological mapping, the authors recognized four lithostratigraphic associations in the Carboniferous Dananhu arc belt within the East Tianshan Mountains. Their rock associations, geochemistry, fossils and spatial relationship together with previously published geochronological data suggest that the previously-thought Dananhu arc is actually made of arc volcanic rocks, back-arc basin sediments and remnant oceanic basin sediments, which are associated with the above-mentioned four units respectively. Thus, the tectonic and evolution framework has been established in association with regional studies. oft-com:office:office" />
