新疆哈密黄山韧性挤压带变形砾石具超塑性拉伸的特征，变形砾石平均棉球体长短轴比（Ｘ／Ｚ）大于１０．变形砾石的微观构造、超微观构造、石英组构、及变形砾石拉伸量与砾内石英颗粒轴比（Ｘ／Ｚ）和砾内面理间隔（Ｄ）关系等的综合研究表明，挤压及其所导致的砾内矿物的细粒化和拉伸及砾内面理间隔的减小是砾石超塑性拉伸的重要变形机制。变形砾石粒度大小和岩性对砾石拉伸变形具一定的敏感性。另外，随着拉伸应变量的增大，硅质岩砾石石英组构有从Ｖ型极密、小圆环带、交叉环带向Ⅷ型极富和Ⅰ型极密演化的特征。 The deformed gravel in Huangshan ductile compaction zone of Hami, Xinjiang is characterized by superplastic stretching. The ratio of major to minor axis (X / Z) of the average size of deformed gravel is more than 10. A comprehensive study of the microstructure, ultramicrostructure, quartz structure, and the relationship between the amount of deformable gravel and the gravel inner-grained axial ratio (X / Z) and the gravel interbedded spacing (D) The granulation and stretching of the gravel minerals and the reduction of interbedded interbedded minerals are the important deformation mechanisms of graphene superplastic stretching. Deformation gravel size and lithology of the gravel deformation with a certain sensitivity. In addition, with the increase of the tensile strain, the gravel-quartz structure of the chert is characterized by the evolution from extremely polar V-shaped, small annular zone and cross-annular zone to Ⅷ type polar and type Ⅰ polar dense.
