WebRock exposures become progressively younger towards the axis of synclines. 9. Rock layers dip away from the fold axis in anticlines, but dip toward the fold axis in synclines. Plunging Folds. 1. Figure 10.10: A fold can be divided by an imaginary surface called the axial plane. The axial plane divides a fold as symmetrically as possible. WebSome kinds of metamorphic rocks -- granite gneiss and biotite schist are two examples -- are strongly banded or foliated. (Foliated means the parallel arrangement of certain mineral grains that gives the rock a striped appearance.) Foliation forms when pressure squeezes the flat or elongate minerals within a rock so they become aligned. fisher fm100b

WebFolds in which the limbs dip toward the hinge and display a more U-like shape are called synclines. They usually flank the sides of anticlines and display opposite characteristics. A syncline's oldest rock strata are in its outer limbs; the rocks become progressively younger toward its hinge.
