【摘要】 通过对凤凰山岩体的野外研究、显微构造、包体测量及磁组构分析，详尽解析凤凰山岩体的侵位构造变形特征，并厘定了岩体变形过程中的应变状态。结果表明凤凰山岩体在 Ｎ Ｎ Ｅ向水平左旋剪切应力及重力的联合作用下呈气球膨胀式同构造侵位的机制。更多还原

【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.更多还原
