Structural geological sections taken from the railway tunnel through the Monte Bove and Saint Mary hills, Aquila-Abruzzi

The stratigraphic and structural data obtained from the study carried out on the samples collected inside the Monte Bove railway tunnel (Carseolani Mts., Abruzzo), allowed a reconstruction of the complicated tectonics of the surrounding area. The sequence recovered inside the tunnel is wholly calcareous and was dated as Late Cretaceous and Middle Miocene. The lithologies are described. The western part of the geologic section is formed by small fragments of monoclines (constituted by Miocene and Cretaceous limestones), affected by subvertical extensional tectonics. The central part is characterized by two ramp-flat structures, which develop on the ductile layer of the "Marne a Orbulina' and generate the overthrust of the Cretaceous limestones on the whole Miocene sequence. The eastern part comprises several fragments of the succession, doubled and repeated by ridge structures associated with a transcurrent phase. -from English summary
