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.

p.17: In the Silvretta nappe the heterogeneous coarse Chazforà conglomerates occur only in a few layers of the basal sequence, concentrated in the Albula valley region. The upper part contains coarse layers of angular vein quartz conglomerates interfingering with a fine grained sandsteon complex (Tuors Mb., ca. 200 m).
