When were the Southern Alps formed?

These mountains are mainly composed of hard sandstone and mudstone, collectively known as “greywacke”, of Mesozoic age, but the southern and western parts of the Southern Alps are formed of schist.

What caused the Southern Alps to form?

The main topographic expression of the Southern Alps was formed in Late Cenozoic times, as the Pacific Plate collided with the Indo-Australian Plate. Collision resulted in the leading edge of the Pacific Plate becoming upturned and rapidly uplifted.

When did the Alps first appear?
