Answer :

Rocks with a hornfels texture are typically found in the region of contact metamorphism, a type of temperature-dependent metamorphism in which pressure has little or no impact.

Contact metamorphism (also known as thermal metamorphism) occurs when rock is heated by the intrusion of hot magma.

The dark grey rock in this photo is an intrusion (a sill) between layers of paler grey limestone. The limestone has been altered to form white marble just above and below the intrusion.

Contact Metamorphism can happen on scales ranging from a few millimeters on either side of a small intrusion to several hundred meters around a large igneous body like a batholith.
