Overprinting relationship among major and minor structures in the sedimentary cover of south-eastern Umbria and northern Latium provide significant information on the modes of compressional deformation propagation in the Umbria-Marche Apennines
The Monte Santa Maria Tiberina ridge consists of a stack of Late Oligocene-Middle miocene siliciclastic turbidite successions belonging to the Tucsan and Umbria domains. In this work a new geological map of the area is presented, based on a review

A geologic survey, integrated with sedimentalogic observations and macrofacies analysis, has been carried out for the Jurassic deposits outcropping in the Mt. Catria - Mt. Acuto area. The study area is located within the northern Umbria-Marche
Early Pleistocene (Santernian: MNN 19b-c Nannofossil Zones) coastal marine deposits related to rocky coast evolution have been described in a wide area near Orvieto (Umbria, Central Italy). Sediments range from boulders and blocks, to rounded
The presence of ammonites in the Bonarelli Level (uppermost Cenomanian) of the Umbria-Marche Succession is reported here for the first time. The horizon studied has been recognised near Serra S. Abbondio, on the external limb of the Mt. Catria
This paper describes the geological and structural setting of an area localized between the Terni basin and the Martani chain in Southern Umbria (Central Italy). This region corresponds with a topic area, a kind of NS transcurrent megashear
The aquifers of the Umbria-Marche Adriatic region : relationships between structural setting and groundwater chemistry
A hypothesis on the hydrogeochemical evolution of the groundwater present in the Apennine limestones, Mio-Pliocene terrigenous deposits and alluvial plain aquifers of the Adriatic-Umbria-Marche area is discussed in this paper. The mineralised
The Umbria-Marche Apennines, an arc-shaped fold and thrust belt form the external part of the Northern Apennines. The AA. suggest that this fold-thrust belt can be divided longitudinally into 2 sectors. The boundary between the eastern and western
parts of the Umbria-Marche Apennines is here termed the Scheggia-Foligno Line (SFL). Various mechanisms might be invoked to explain the discontinuity at this SFL. The possible explanations include causes of local character, linked to the sedimentary
and tectonic evolution of the region. However, it also possible that the Western and Eastern Umbria-Marche Apennines represent completely different orogenic systems, with different causes - possibly with the former related to Corsica-Adria collision
