Abstract: | Detailed gravity data in conjunction with available surface geology are analyzed to infer the organization of the underlying
structures in Jendouba area. Gravity data analysis benefits from the gravity Bouguer anomaly, upward continuations, residual
distribution, derivatives and Euler deconvolved maps. The main results display a positive amplitude gravity anomaly as the
response of Triassic evaporitic bodies and important NE trending features at the boundaries between the Triassic outcrops
and their enveloping strata. Integration of gravity, geological and structural maps let to the identification of major structural
directions and trends of the study area. It confirms some structural elements gathered from outcrops. It defines also new
ones. |
