  • Analysis of the geo-environmental conditions as morphological evolution factors of the sand-clay series of the Tiber valley and Dunarobba forest preservation


The excavation of clay for bricks production in a quarry close to Dunarobba (Umbria region, central Italy) brought to light a significant number of upright sequoia tree trunks. Their outstanding state of preservation led to the site being considered as a natural analogue; therefore, research was undertaken aimed at analysing the characteristics of the soil masses which have been protecting the trunks and at evaluating the effects which have been induced by vulnerability factors acting at the boundaries of the host system. Geophysical investigations, soil gas prospecting, geological and structural surveys, as well as logs from mechanical boreholes allowed the reconstruction of the evolution and the present boundary conditions of the satellite basin where Dunarobba forest is located.
