Abstract
The CARG Project, started in 1988, aims to update and to upgrade the Geological
Map of Italy through the realization of new geological sheets at 1:50.000 scale. The
project produces a well detailed modern cartography with an useful data base
(1:25.000 scale) that allows GIS analysis, citizen science application and 3D
modelling.
The analysis of the geological maps of large urban areas is performed since 2nd
Report about urban environmental quality, published in 2005. Geology of urban areas
is a focus for geological mapping in order to reconstruct surface and deep setting of
the territory that is hidden by buildings and infrastructures. Lithological,
paleontological, mineralogical and structural characteristics are achieved through
wells and geophysical analysis. These data are useful to reconstruct stratigraphical
setting, geometries of rock bodies and to identify aquifers. Moreover
geomorphological dynamics and their areal extension can be described supporting
analysis of the interaction between development plans and urban environment.
Improving studies about geological hazard in urban areas support risk analysis
(flooding, volcanic, seismic), groundwater supplies, soil sealing, the recovery of areas
degraded by pollution.
