Nonlinear inversion of isostatic residual gravity data from Montage Basin, northern Gulf of California

摘要: ABSTRACTThe flexural isostatic response to surface loads is used estimate the crustal thickness in northwestern Mexico and Southwestern USA. This compute an regional gravity, which, subtracted from Bouguer gravity anomalies, led residual anomaly at Montage Basin. basin located between southern portion of Mexicali Valley northern Gulf California, it roughly has extension 100  km long×40  km wide, shows a minimum reaching approximately −65  mGal. Basin within extensional province where rifting currently ongoing geologic process, deep exploratory wells drilled by Petroleos Mexicanos have shown that accommodates thick sedimentary sequences greater than 5 km. The interpretation considered as nonlinear inverse problem, constrained using density function depth derived Gardner’s equation a...
