| Abstract: | The palaeoproterozoic extensional structure in the east of Liaoning Province underwent sub - bedding ductile shear flowing deformation with metamorphism and magmatic emplacement. The reversal structure following the processes constructed the present framework of palaeoproterozoic orogenic belt. As a result of the ductile shearing along the layers, the gold in the Liaohe group was activated, migrated upward to the interface between the Dashiqiao rock formation, which was lower green schist facies and the Gaixian rock formation, so the gold deposit was formed in the space of brittle - ductile shear zone as ductile - shear - zone - typed stratabound gold deposit. |
