Recem Ocean Drilling Program sampling of the Ctte d'Ivoire-Ghana margin of West Africa provides for the first time the opportunity to study the development of a marginal ridge that formed along a sheared passive margin adjacent to the continent-ocean transition after the end of intmcontinemal wrenching. We model its evolution using a two dimensional flexural backstripping technique. The model i...

The boundary between the crust and the mantle was discovered by Mohorovicic in 1909 under the European continent. Subsquent research in this century established the major differences between the continental and oceanic crust; a typical thickness for the continental crust is 30-50 km while a typical thickness for me oceanic crusts is 6 km. In terms of history the continental crust contains a muc...

[1] Surface wave dispersion measurements from ambient seismic noise and array‐based measurements from teleseismic earthquakes observed with the EarthScope/USArray Transportable Array (TA) are inverted using a Monte Carlo method for a 3‐D VS model of the crust and uppermost mantle beneath the western United States. The combination of data from these methods produces exceptionally broadband dispe...

Abstract. When interpreting geophysical models, we need to establish a link between the models' physical parameters and geological units. To define these connections, it is crucial consider compare models with multiple, independent parameters. Particularly in complex scenarios, such as rifted passive margin offshore Namibia, multi-parameter analysis joint inversion are key techniques for compre...

Abstract The best exposed Early Miocene (820 m. thick. ) shales and interbedded silty sandstones beds of the Pyawbwe Formation at Sakangyi- Thayat area,Magway Region are investigated geochemically by using Siemens SRS- X Ray 303 AS XRF Spectrometer. Major and some trace element concentrations have been determined to achieve their provenance, tectonic setting ,paleoweathering , paleoclimate and ...

An investigation of Curie point depths (CPD) based on spectral analysis airborne magnetic data was carried out in the NE Brazilian continental margin. The studied region represents a narrow hyper-extended margin with three sedimentary basins. Regional geothermal gradient and heat flow were also calculated. CPD results integrated interpretation 2D deep seismic estimated isostatic Moho depths. re...
