[SGD01-04] Microgravity Inversion for 3D subsurface density modeling of Al-Ain Region, Abu Dhabi, United Arab Emirates.
Keywords:Microgravity survey , 3D density Inversion, Al-Ain, Geobody Modeling, Low-density in Carbonates
The gravity measurements helped to delineate the subsurface density distribution beneath the city using a microgravity 3D density inversion scheme. The inversion results allowed mapping the substructure of mount Hafeet in the south and detect low-density materials at the center of the city near the surface. This low-density material correlates with the Eocene-Oligocene Asmari formation, known to be karstic and cavernous at the bedrock outcrop, suggesting the presence of near surface karstic systems.
