Why are rift zones common places for igneous rocks?
The thin crust of a rift zone causes melting in the upper mantle, resulting in volcanic activity.
Why are rift zones a common spot for igneous rock to form?
The thinned crust in rift zones results in the formation of magma (molten rock) in the upper mantle, which then rises through the crust. As a result, rift zones often have active volcanoes, which form new igneous rocks.

Igneous for sure. Also metamorphic.
What are the characteristics of a rift valley?
Igneous. Crustal material is added in rift valleys by the addition of magma.
How do rift valleys form?
