The type of mountain involving huge sections of the crust being pushed up into anticlines and synclines is called a folded mountain.

Here's a breakdown:

* Anticlines: Upward folds in the rock layers, forming the peaks of the mountain.

* Synclines: Downward folds in the rock layers, forming the valleys between the peaks.

Folded mountains are formed through a process called compression, where tectonic plates collide and push the rock layers together, causing them to bend and fold. The Himalayas and the Appalachian Mountains are examples of folded mountain ranges.
