Abstract

The metamorphic rock cycle is a crucial component of the Earth's dynamic geological processes, illustrating the transformation of sedimentary rocks into metamorphic rocks under varying pressure, temperature, and fluid conditions. This process begins with the burial and diagenesis of sedimentary rocks, leading to increased compaction and mineral changes as they are subjected to greater depths. As these rocks encounter the elevated pressures and temperatures of the Earth's crust, they undergo recrystallization, forming new mineral assemblages and textures characteristic of metamorphic rocks. This transformation occurs in diverse geological settings, including regional metamorphism associated with tectonic collisions, contact metamorphism near magmatic intrusions, and high-pressure metamorphism in subduction zones. Understanding the metamorphic rock cycle provides valuable insights into the tectonic history and evolution of the Earth's crust, offering a window into the processes that shape our planet over geological time.
