How old is the nazca plate
NettetThe Neogene history of the Andes begins with the breakup of the Farallon Plate into the Nazca and Cocos Plates at ∼28–26 Ma. This event is linked to the change in convergence direction and increase in relative convergence velocity that led to the major uplift of the Andes that culminated in the Late Miocene and Pliocene.

The average spreading rates are greater for the Pacific-Nazca plates than the Cocos-Nazca plates. This area represents an area of fast seafloor spreading. 7.

The structural features and evolution of the northern Nazca plate can be explained by the existence of an east-trending spreading center in the eastern Pacific from approximately 40 to 25 m.y. ago, and reorganization of spreading centers about 10 m.y. ago.
