ABSTRACT: The Lidfjellet thrust is the most prominent tectonic structure in the Lid− fjellet−Øyrlandsodden fold zone, which stretches NNW−SSE along the western coast of Sørkapp Land in Spitsbergen. This paper provides a reinterpretation of the Lidfjellet struc− ture, with particular reference to lithostratigraphy of the autochthonous and overthrust se− quences involved, and to the position of the thrust surface. Geological and palynologicalal data indicate that the sequence attributed previously to the Lower Cretaceous Helvetiafjellet Formation of the autochthonous cover represents in fact the Carboniferous (Viséan) Sergeijevfjellet Formation forming the lower part of the overthrust unit. The youngest de− posits involved in tectonic structures of the Lidfjellet−Øyrlandsodden fold zone are of Up− per Jurassic age.
