 Abstract

Detailed structural analysis and mapping in the Lavagna Nappe reveals the effect of various phases of deformation on a regional scale. The earliest phase produced large isoclinal, originally SW-facing folds (F1). A second phase led to the development of open folds (F2). The vergence of the younger folds (F3, F4) is NE. Thrusting occurred in two stages: postF2-pr F3 and synF4. Hereafter the previously stacked thrustsheets, together forming the Lavagna Nappe, were emplaced on top of the Melange Nappe by NE-directed trusting. A final phase of gentle folding (F5) caused an undulation of all older structures.
