Clay Minerals (2001) 36 (2): 159-170.
...M. BURKHARD; D. GOY-EGGENBERGER Abstract Metamorphic isograd surfaces are mapped within the Morcles nappe using illite crystallinity (IC) and (clay-) mineral parageneses in 268 samples. The diagenesis-anchizone and the anchizone-epizone boundaries are nearly vertical surfaces which crosscut...

...M. BURKHARD; N. BADERTSCHER Abstract The relationship between illite crystallinity (IC) and finite strain as well as lattice strain and crystallite size of illite is examined in a series of 27 deformed breccia samples from the inverted limb of the Morcles nappe. The IC is determined independently...

Bulletin de la Société Géologique de France (1949) S5-XIX (7-9): 629-639.
...Leon Feugueur Abstract Discusses the Nummulitic (Tertiary) stratigraphy of the Araches plateau and the Cretaceous-Eocene stratigraphy and structure of the Arbaron mountain which rises above the plateau, in the Plate massif region, France. Both the plateau and the mountain belong to the Morcles...

F ig . 5. Sample localities and the occurrence of index minerals within the Morcles nappe, projected onto a simplified horizontal cross-section of the nappe at 1500 m a.s.l. The ICs of the air-dried <2 μm clay fraction were used to calculate isocryst contours obtained by linear interpolation

... terrane of the newly inactive, but still hot, spreading ridge. The development of the Grampian orogen, as first described here, is not unique as close analogies may be drawn with the kinetic models proposed for the Saih Hatat fold-nappe in Oman, and the Morcles Nappe in the Swiss Alps. In both cases...
