Resumo: | Investigations of convergent margins along the IPOD transects support the concept of ocean floor spreading in back-arc basins and the concept of tectonically accreted sediment at the front of convergent margins. However, not all convergent margins have large accreted complexes, and other less frequently used concepts are required in the interpretations of these convergent margins. If the present rates of plate convergence are accepted, then much sediment that entered the trenches studied is presumably subducted rather than accreted. In some instances, the continental framework is truncated and somehow removed by tectonic erosion. Some convergent margins have subsided significantly during subduction. The crust above the Benioff zone appears to have been thinned by subcrustal erosion or the configuration of the Wadati-Benioff has changed. However, since only part of the subsidence can be explained by erosion, the change in thermal structure resulting from changing rates of subduction may be the major cause. To differentiate subduction-related processes commonly requires time-stratigraphic information from drill samples to make a kinematic reconstruction of the margin.
