Abstract
An integrated geophysical MVG (Microgravity Vertical Gradient) and ERT
(Electrical Resistivity Tomography) survey was performed over a shallow
cave in the Armetta Mountain karst area, close to the Liguria-Piedmont wa-
tershed (Tanaro valley). The aim of this study is to test the response of a
known shallow karst cave. The cave was developed in the Mesozoic sedimen-
tary cover (dolostones and limestones - CAU : Caprauna Armetta Unit); the
shallowest portion of the cave exhibits narrow passages and, at about 30 m
below the entrance, a fossil meander which links two large chambers, that
represent the target of the geophysical survey.....
