Formation processes Anticline

anticline near ehden, lebanon

anticlines developed above thrust faults, small compression , motion within inner crust can have large effects on upper rock stratum. stresses developed during mountain building or during other tectonic processes can warp or bend bedding , foliation (or other planar features). more underlying fault tectonically uplifted, more strata deformed , must adapt new shapes. shape formed dependent on properties , cohesion of different types of rock within each layer.

during formation of flexural-slip folds, different rock layers form parallel-slip folds accommodate buckling. way visualize how multiple layers manipulated, bend deck of cards , imagine each card layer of rock stratum. amount of slip on each side of anticline increases hinge inflection point.

passive-flow folds form when rock soft behaves weak plastic , flows. in process different parts of rock body move @ different rates causing shear stress gradually shift layer layer. there no mechanical contrast between layers in type of fold. passive-flow folds extremely dependent on rock composition of stratum , can typically occur in areas high temperatures.
