crustfixed

Crustfixed is a term used in the field of geology to describe a type of igneous intrusion that occurs when magma rises from the Earth's mantle and solidifies at shallow depths within the crust. This process results in the formation of a pluton, which is a large body of intrusive igneous rock. Crustfixed intrusions are typically characterized by their large size, slow cooling, and the absence of significant volcanic activity at the surface. Examples of crustfixed intrusions include batholiths and stocks. These intrusions can have significant economic importance, as they often host valuable mineral deposits such as gold, copper, and other metals. The study of crustfixed intrusions provides valuable insights into the dynamics of the Earth's crust and the processes that shape our planet's geology.
