| 摘 要： | 本文讨论了伯顺岬地区海克拉霍克岩系的变质岩小构造特征。主要的线理有窗棂构造、布丁构造、小褶皱怄纽线理、褶纹线理、拉伸线理、交线线理和剪切线理等;主要面理除原生层理外,还有早期次生面理S_1与晚期次生面理S_2。新生线理和面理与不同形变期的主褶皱有密切的伴生、组合关系。变质岩小构造的研究为恢复区域构造形变历史提供了丰富的证据。

| Abstract: | The minor structures of metamorphic rocks of Hecla Hoek Seque?ce exposed in Kapp Borthen area arediscussed. Seven kinds of lineation have been recognised: 1) mullion structure, 2) boudinage structure,3) small fold-hinge lineation, 4) crenulation lineation, 5) stretching lineation, 6) intersection lineation and7) shear lineation. Three types or foliation including primary bedding So, early secondary foliation S_1 andlate secondary foliation S_2 have been established. All of these lineations and foliations are closely relatedto the main folds which formed in different deformation stages. On the basis of lineation and foliationstudy the history of regional tectonic deformation has been reconstructed. |
