| contents | This chapter describes the main geophysical methods used when studying offshore rifts and rifted margins. Geophysical data are often the only constraints available for interpretation of offshore rifted continental margins. Seismic reflection, refraction and potential fields are all valuable datasets carrying relevant information. In the absence of rock samples, geophysical methods are the only way to study rifted margins. They provide indirect imaging of the crust and sediments, as well as potential field data. There is a large spectrum of interpretations for rifted margins. Sometimes it is linked to the large diversity of rifted margins, sometimes it is linked to different geological scenarios. It is thus important to understand how each geological or geophysical object is recognized and their possible interpretation. In marine geophysics, the free-air gravity anomaly is computed from raw data. |
