The thin crust of a rift zone causes melting in the upper mantle, resulting in volcanic activity.
so magma can cool below earth surface to from igneous rocks.
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.
A type of rock that would likely form from magma solidifying at considerable depth beneath subduction zones is basalt. Basalt is a common igneous rock formed from the solidification of mafic magma, which is typical of volcanic activity at subduction zones. It is fine-grained and commonly found in the oceanic crust formed at these zones.
There are many explanation to your question. The most abundant type of rocks in collision zones are metamorphic rocks. But if there is a igneous it can as a result of convergence boundaries. In subduction zones where rising magma are penetrate through weaker rocks to form form lava and when solidified forms igneous rocks. You can also find them in accretion zones. Where 2 continental plates are accreted due to plate movement. They are not newly formed igneous. they have been there for years before accretion.

Igneous rocks form only in certain places. Fractionation occurs mostly where tectonic plates are either moving apart at mid ocean ridges or pushing together at subduction zones.

Usually deep underground from heat and pressure, at regional metamorphic zones in areas of continental collisions, and in contact zones where parent rock is metamorphosed from proximity to an intrusive igneous body.
Yes it can form an igneous rocks as because of pressure it may melt and form into igneous rocks.
Most igneous activity takes place along tectonic plate boundaries, such as divergent boundaries where plates are moving apart or convergent boundaries where plates are colliding. This is because the movement of the plates creates the conditions for magma to form and rise to the surface. Subduction zones and hot spots are also common locations for igneous activity.
Intrusive igneous rocks form beneath the Earth's surface in settings like magma chambers and batholiths. Extrusive igneous rocks form on the Earth's surface from volcanic eruptions, such as at mid-ocean ridges, subduction zones, and hot spots.
Three methods of intrusive igneous rock formation are magma cooling and solidifying deep within the Earth's crust, magma forcing its way into existing rock formations and solidifying, and magma being injected into cracks and crevices in the surrounding rocks and cooling to form igneous rocks.
