The Vinschgau Shear Zone represents the structurally highest unit of the Campo Nappe Complex and constitutes a greenschist-facies Alpine mylonitic belt with a thickness of up to 2–3 km that accommodates W-directed thrusting of the Ötztal Nappe Complex in the area north of the Vinschgau Valley floor. South of the valley floor and in the lowermost Val Müstair, the same mylonitic belt accommodates WNW-directed thrusting of the easternmost part of the Umbrail-Terza Slice Complex over the S-charl-Sesvenna Nappe.
