Foliation lineation
WebMay 28, 2024 · The structural study of shear zones is thus carried out in the XZ plane of finite strain (i. orthogonal to the foliation plane and parallel to the stretching lineation), which is also the ac kinematic plane since the lineation is parallel to the displacement direction c. Extending the fold terminology, this plane can be called the profile of a ... Webfoliation and stretching lineation is widely recognized in modern tectonic studies since these structures represent the most basic and fundamental observations directly related to the flow of rocks in orogenic areas. Consequently, the absence of macroscopically visible planar and/or linear structures impedes any reliable kinematic analysis, a

The second phase is marked by fold (F2), lineation (L2), and boudins (B2). The third phase is marked by subvertical foliation (S3), shear (C3), and lineation (L3). The fourth phase is essentially a brittle phase. Granites present mostly magmatic deformation features; meanwhile, granite mylonites …
