| Abstract:Based on field investigation, micro_structure studies, measuring of enclaves and magnetic fabrics of Fenghuangshan pluton, this paper analyses in detail the characteristics of structural deformation with the emplacement of pluton,and determines the strain features during the deformation. ;The results indicate that the pluton was of syntectonic balloon_like emplacement mechanism under the force of NNE_trending sinistral ductile shear and gravity. |
