Furrer Heinz (Ed.) (1985) : Field workshop on Triassic and Jurassic sediments in the Eastern Alps of Switzerland. Mitt. geol. Inst. ETH und Univ. Zürich (N.F.) 248, 81 S.

An imbricated sheet of Upper Triassic carbonate rocks thrust to the SW or S over the Ortler sediments along the Trupchun-Braulio Line. The Quattervals nappe is part of the S-charl nappe affected by "back-thrusting". It is separated from the S-charl nappe by the complex fault (lag?) of the Gallo Line.
