Variscan ductile normal faulting is described in the formations of Les
Sables-d'Olonne (Vendee coast, France). The observed structures are l
ocalized in gneisses at the base of a metasedimentary pile. They chara
cterize an eastward normal ductile shear with a dextral component. Thi
s tectonic event, which postdates a westward tangential kinematic epis
ode, is probably the western exression of the late Massif Central duct
ile normal shears.
