Description:
The understanding of the tectonic processes shaping the Pacific margin off Costa Rica has undergone a dramatic evolution during the past 25 years. The margin, initially interpreted to be built by accretion of sediment from the ocean plate, is now interpreted as made of ophiolitic rocks that are exposed onshore, with no net accretion currently active. New seismic images indicate that upper plate tectonic erosion might be the dominant process. Erosion is accomplished in some cases through transport of large bodies from upper to lower plate by plate boundary readjustment. Subduction of seamounts locally accelerates tectonic erosion.
