Preliminary magnetic fabric studies in the mafic dykes, using Anisotropy of Magnetic Susceptibly （AMS） studies at low-field, indicate successive emplacement and variable magma flow direction. Magnetic lineation and foliation in these dykes are identical to the mesoscopic fabrics in MSZ mylonites, indicating shear zone guided emplacement. Spatial distribution of magnetic lineation in the dykes suggests a common conduit from which the source magma has been migrated. The magnetic foliation trajectories have a sigmoidal shape to the north of the pluton and curve into the MSZ suggesting dextral sense of shear. Identical fabric conditions for magnetic fabrics in the syenite pluton and measured field fabrics in mylonite indicate syntectonic emplacement along the Proterozoic crustal scale dextral shear zone with repeated reactivation history.展开更多

It is true that no Free Economic Zones （FEZs） in the world like in China have made so strong impact on national economic development and structural reform. Due to the change of their existing condition since the middle of 1990s, Chinese FEZs have to face the new challenges and problems. This study discusses and prospects the transformation and further development of Chinese FEZs in the 21^st century as well as their significance for the transformation of FEZs in other countries based on the analysis of the indicators such as the role, policy, industrial sectors, administration, development model, spatial structure and location.展开更多
