Which property remains unaffected during the rock cycle?

The chemical composition of a rock's constituent minerals generally remains unaffected during the rock cycle, despite the physical changes and transformations that occur. While rocks can change from one type to another (igneous, sedimentary, metamorphic) through processes like melting, erosion, and metamorphism, the fundamental minerals that make up the rock retain their chemical identity. However, the arrangement and texture of these minerals may change significantly.
