Which rocks texture is determine by the pressure and temperature the rock was exposed to?

The texture of metamorphic rocks is primarily determined by the pressure and temperature conditions they are exposed to during metamorphism. As these rocks undergo changes, their minerals can realign or recrystallize, resulting in textures such as foliation, which is the layering of minerals, or non-foliated textures, where the minerals are interlocked without a layered appearance. This process can create a range of textures, from coarse to fine, depending on the specific conditions experienced.
