The continent-ocean boundary ( COB ) or continent-ocean transition ( COT ) or continent-ocean transition zone (COTZ) is the boundary between continental crust and oceanic crust on a passive margin or the zone of transition between these two crustal types. The identification of continent-ocean boundaries is important in the definition of plate boundaries at the time of break-up when trying to reconstruct the geometry and position of ancient continents e.g. in the reconstruction of Pangaea .

Moho depth can be derived by the inversion of satellite gravity data, taking into account the lithosphere thermal gravity anomaly. Crustal thickness can then be derived by subtracting this from

On normal incidence seismic reflection data recorded to sufficient depths, the Moho can in some areas be directly imaged, allowing the identification of normal thickness oceanic crust. The combined use of seismic wide-angle reflection and refraction data give a precise location for
260-517: The COB by determining the P-wave velocities along a profile. The two types of crust have distinct P-wave velocities. As hydrocarbon exploration moves further offshore to look for the remaining potential on passive margins, understanding the location of the COB is critical to predicting possible hydrocarbon occurrence. This is both from the likely location of source and reservoir rocks and the need to model

Most areas of oceanic crust show characteristic stripes due to periodic magnetic reversals during formation at a mid-oceanic ridge . The continental crust is by contrast typically magnetically quiet. This method is dependent on stripes being present and will not work for oceanic crust created during
