摘　　要：徐宿弧形构造在构造演化和成因机制上均具有特殊意义。在综合分析区域构造背景和构造演化的基础上,结合野外构造观测进行定向岩样薄片观察,鉴定不同构造部位的显微构造特征。研究表明,该区脆性及塑形显微构造均有不同程度的发育,中浅层以低温脆性流变特征为主,且受多期次构造运动相互干扰和叠加,呈现出复杂多变的构造演化过程。Are Tectonics of Xuzhou-Suzhou region l-as special significance on the tectonic evolution and formation mechanism. On the basis of comprehensive analysis of regional tectonic setting and tectonic evolution, take an observation on the thin slices of particular rock samples with field tectonic observations to identify the microstructure characteristics of the different tectonic parts. Studies have shown that brittleness and shaping microstructure in this area have developed in varying degrees. The shallow layer mainly on the low temperature brittleness theological characteristics interfered and superimposed by muhi-stage tectonic .movements, showing a complex and changing tectonic evolutional process.
