Results from laboratory analyses of thermophysical properties and mineralogical composition of rocks belonging to the main geological formations of the Umbria-Marche stratigraphic succession are presented. We carried out measurements of thermal conductivity, porosity, and density. The samples were mineralogically characterized by means of powder X-ray diffraction and by calcimetry. Scanning electron microscope analyses were conducted to ascertain the absence of mineralized veins, which could have biased the mineralogical composition. A mixing model was also applied to infer the thermal conductivity. The results can be useful to characterize the behavior of shallow geothermal systems in the study region.

250 Million Years of Earth History in Central Italy: Celebrating 25 Years of the Geological Observatory of Coldigioco
Central Italy has been a cradle of geology for centuries. For more than 100 years, studies at the Umbria and Marche Apennines have led to new ideas and a better understanding of the past, such as the Cretaceous-Paleogene (K-Pg) boundary event, or the events across the Eocene-Oligocene transition from a greenhouse to an icehouse world. The Umbria-Marche Apennines are entirely made of marine sedimentary rocks, representing a continuous record of the geotectonic evolution of an epeiric sea from the Early Triassic to the Pleistocene. The book includes reviews and original research works accomplished with the support of the Geological Observatory of Coldigioco, an independent research and educational center, which was founded in an abandoned medieval hamlet near Apiro in 1992.
