Abstract EN
The map of complete Bouguer anomaly of Costa Rica shows an elongated NW-SE trending gravity low in the central region.
This gravity low coincides with the geographical region known as the Cordillera Volcánica Central.
It is built by geologic and morpho-tectonic units which consist of Quaternary volcanic edifices.
For quantitative interpretation of the sources of the anomaly and the characterization of fluid pathways and reservoirs of arc magmatism, a constrained 3D density model of the upper crust was designed by means of forward modeling.
The density model is constrained by simplified surface geology, previously published seismic tomography and P-wave velocity models, which stem from wide-angle refraction seismic, as well as results from methods of direct interpretation of the gravity field obtained for this work.
The model takes into account the effects and influence of subduction-related Neogene through Quaternary arc magmatism on the upper crust.
