Pompeii geoarchaeological setting – An archive older than 40,000 years of volcanism, soil formation and geoarchaeological landscape
No full textThe present work describes the results of full lithostratigraphic, pedological and geoarchaeological studies carried out
in the Pompeii archaeological area (southern Italy), combined with logs data, surface and underground survey of lava and
tephra outcrops. The ancient Pompeii is probably the most famous and complex site of archaeological investigation in the
world. Through many studies have been devoted to various archaeological aspects, detailed reconstructions of the
geological setting and history of geoarchaeological landscapes are still lacking. At present, Pompeii landscape consists
of low hills recognized as volcanic landforms and attributed to the Somma-Vesuvius volcano activity; they correspond to
ancient local vents covered of a multilayered succession of repeated volcanic deposits and paleosoils, mainly related to
alternating volcanic activity and quiescence periods with consequent pedogenesis (De Maio and Stefani, 2004;
D’Ambrosio et al., 2001; Cinque and Irollo, 2004). This succession comprises at least the last 40,000 years of
sedimentation history, reflecting the entire spectrum of eruption types of the Somma-Vesuvius, i.e. from Plinian to sub-
Plinian eruptions, relatively small eruptions to effusive volcanic events and, on the other hand, soil formations of different
durations, intensities and soil-forming environments. Before the foundation of the city, paleosoils repeatedly reveal clear
evidence of anthropogenic activity, represented by agricultural practices. Once the city has taken to develop,
anthropogenic landscape changes become particularly pronounced. The various periods of edification of the city walls
required different types of land management, related to the variable morphological profiles encountered along of
defensive wall circuit (longer than 3 km). Outcrops were deeply modified with quarries, underground excavations,
earthworks. Several wells were drilled deeper than 20 meters to reach the water table. Two main geological sections,
carried out through the Tempio di Venere and the Regio VIII Insula southern lava cliff, show a core of lavas locally
capping buried deposits of the Campanian Ignimbrite. Geological risk assessment in such a complex archaeological site
needs specific evaluations/methods and flexibility, according to specific conditions and case studies.

Full text linkThis study uses a randomized control trial to evaluate the outcome of integrating money management and entrepreneurial training into a microcredit program in India. We find positive and significant effects on clients’ financial management skills and entrepreneurship abilities, particularly for clients with higher human capital, or more diligent, or having an entrepreneurial idea, and an increase in initiative and self-confidence. Effects appear stronger for clients obliged to attend the training course or more interested in attending it. By considering missed or delayed repayments reduction we assess the benefits of the training provided and of extending it for the institution
