Title: | Integrated MVG and ERT Survey Over a Shallow Cave | Issue Date: | 26-May-2009 | Keywords: | Karst Studied, Electrical Resistivity Tomography Microgravity Vertical Gradient, Void detection |
Subject Classification: | 04. Solid Earth::04.02. Exploration geophysics::04.02.99. General or miscellaneous | 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..... |
