Morcles Nappe - upper limb

The upper limb of the Morcles nappe contains rocks that are only weakly deformed.  The larger-scale folds on this limb generally preserve bed-thickness from limb to hinge. On an outcrop scale there is abundent evidence for amlounts of pressure solution and reprecipitation - pitted  Tertiary conglomerates and conjugate vein arrays.

Looking down onto a bedding plane view of conglomerates (Tertiary in age).  Pay particular attention to the shapes of the clasts and the nature of their edges.  Use this to infer how these rocks have been deformed.  You should compare these features and your deductions with those made on similar rock types on the lower limb of the nappe.

Conjugate vein array developed in Cretaceous limestones.  These veins are filled with calcite and are seen on a bedding plane.
