Abstract: AbstractDeciphering the pre‐orogenic evolution of subducted continental basement is challenging due to pervasive reworking of crust during subduction and exhumation. Survival of such polycyclic basement may occur locally in low strain domains bounded by intensely overprinted rocks. The Palaeozoic history of basement involved in Alpine continental subduction is investigated in the northern Dora‐Maira Massif where a kilometre‐scale domain of low strain preserves a pre‐Alpine amphibolite‐facies foliation in garnet‐biotite orthogneiss a...
