From the northern limit of this marginal rift zone to 90-180 km farther oceanward, Eittreim et al. (1985), Eittreim and Smith (1987), Colwell et al. (2006), and Leitchenkov et al. (2007b) identified a COT consisting primarily of strongly stretched and faulted continental crust with embedded magmatic segments following linear trends parallel to the margin. The interpretation of the COB along parts of the margin is debatable, as mainly basement characteristics were used for the differentiation of crustal types.
