Which mountains are among world's oldest?

Alps
Carpathians
Urals
Pyrenees
The Urals are among the world's oldest extant mountain ranges. For its age of 250 to 300 million years of age, the el­e­va­tion of the moun­tains is un­usu­al­ly high. They were formed during the Uralian orogeny due to the col­li­sion of the eastern edge of the su­per­con­ti­nent Lau­rus­sia with the young and rhe­o­log­i­cal­ly weak con­ti­nent of Kaza­khsta­ni­a, which now un­der­lies much of Kaza­khstan and West Siberia west of the Irtysh, and in­ter­ven­ing island arcs. The col­li­sion lasted nearly 90 million years in the late Car­bonif­er­ous – early Tri­as­sic.
