Regional shear variation in relation to diapirism and folding |
|
| Authors: | Jean-Pierre Burg |
| Abstract: | Regional structural trends in the Lévézou area (southern Massif Central, France) delineate an antiformal structure. Deformed granitoids display changes along strike in S---C plane relationships, and therefore in sense of shear. These variations are interpreted to be strain accommodation features that developed during the diapiric emplacement and folding of the granitoid sheets, and so cannot be used as kinematic indicators on a regional scale. |
