The Chile Rise or Chile Ridge is a mid-ocean ridge in the Pacific, off the coast of Chile. On the ridge, the Nazca plate and the Antarctic plate meet.

  Fig-2 shows the geology of the Taitao Peninsula. Taitao granites and Taitao ophiolites would be mainly focused on in this part. Chile ridge is located west of the Taitao Peninsula, and the geology of Chile Ridge is closely associated with that of Taitao Peninsula.

  Fig-3 shows a close up view of the spreading Chile Ridge. With difference relative plane motion of Nazca Plate and Antarctica plate, this creates an extensional force for sea floor spreading to carry out.

  Fig-5 This sketch shows the cross-section of the slab window. The Nazca plate and Antarctic Plate is colliding with South American Plate.

  Fig-6 This figure shows the slab window caused by the subduction of Chile ridge, slab window also brings about a seismic gap. The black lines are fault zones (FZ) and the red lines are Chile ridge segments. The dark blue spot is the Chile Triple Junction (CTJ).

  Fig-8 The contour lines show the hourglass morphology of one of the segments of the Chile Ridge. Below is the cross-section of the Chile Ridge topography.
