Morphology

upthrust = thrust (semi-transparent) = up + thrust

Formally 'up' + 'thrust' is clear, but the sense is a technical geological term referring to land uplift, which is specialized vocabulary.

Etymology

Upthrust comes from up ('up') and thrust ('push'), so it means a 'push up' of the land when the Earth's forces lift ground into mountains.
