    The travertine of Carvanno (Brescia) - The lithofacies of travertine of the Carvanno area are described in detail. These deposits form the core of «Morphological Units» located at different altitudes and formed in different times during the Pleistocene. The deposition of the travertine is probably, from the evidence of morphological and morphostructural analyses, connected with the circulation of thermomineral waters rising through tectonic contacts on the right of the Degagna Valley. Their subsequent levelling to terraces is due to variations in the base level of the rivers, connected with tectonic movements

    The geological map of the V. Vrenda-M. Pizzocolo area (1:25.000) is the partial result of studies carried out for several years and that are still in progress in the Brescian Prealps. The explanatory text briefly describes the different rock formations as well as Quaternary informal units and it is completed by a long bibliographical list which can supply further information to enhance the geological knowledge and the regional description of this area. Several variations have modified the previous cartography and the new data introduce elements to reinterpret the paleogeographic evolution of the area. New data allows an updating of the tectonic evolution of the Prealps; the Quaternary deposits have been distinguished into several informal stratigraphic units. Geomorphological symbols complete the map: karst features, fluvial erosional cliffs, moraine ridges and other glacial and fluvioglacial features have been mapped, as well as gravel and limestone quarries

    Nuovi dati sull'assetto geologico e sull'evoluzione paleogeografica giurassica del M. Coro (Val Sabbia, Brescia). New data n the geologic setting and on the Jurassic paleogeographic evolution of the M. Coro (Sabbia Valley, Brescia, Southern Alps).

    The Liassic carbonate sequence outcropping on the M. Coro area was affected by extensional events causing its break-up and the sinking of blocks of marginal platform. The irregular relief was the site of gravitational slides along new formed fault-slopes. The movement took place along sub-parallel sets of planes during the Early Jurassic. Fragments of platform (Corna limestone) were therefore resedimented at the footwall of faults (megabreccias) or interbedded as olistoliths into the pelagic sequence (Medolo Formation) at different levels. The geological researches, extended outside the M. Coro area, give moreover evidence of the paleorelief: highs are located west- and north-wards (Teglie), lows along the well-exposed section of the Chiese River (South of Vobarno)
