چکیده انگلیسی
The Akitkan orogenic belt is a composite crustal unit of Archaean and Palaeoproterozoic age. We propose two possible scenarios of its evolution. In the first scenario Palaeoproterozoic complexes developed along the active margin of the Archaean Anabar superterrane at 2.1-2.0Â Ga. Alternatively Archaean and Palaeoproterozoic components of the Akitkan belt could have a distal origin and were accreted to the Anabar superterrane. These accretional processes were followed by a major collision of the Aldan and Anabar superterranes at â¼1.9Â Ga finalised by post-collisional granitoid magmatism at 1.87-1.84Â Ga.
