| 摘 要： | 变质核杂岩体是区域性伸展构造的主要类型之一。安徽怀宁即是这种构造在大陆板块内部发育并得到保存的典型地区。通过区域大比例尺构造解析认为:怀宁古变质核杂岩体自下而上由变质核、基底剥离断层、褶叠层及盖层4个部分组成。其经历了2次伸展体制及2次收缩体制的构造叠加,形成了一个多期复合变形变质的古变质核杂岩体。

| Abstract: | The metamorphic core complexes are of one of the major types of regionalextensional structure. Huaining is a typical area formed and existing withinthe continetal plate. In the light of large-scale tectonic analysis, it isrecongnized that the Huaining paleometamorphic core complexes consistof metamorphic core, basement denudational fault, folding layers andcover. It has undergone tectonic superinpositions on two extensional systemsand two contraction systems, resulting in a multicyclic and compositepaleometamorphic core complexes of metamorphism and deformation history. |
