Quick Summary

Pyrometamorphism is a geological process where rocks are altered by heat without significant pressure or the presence of mineralizers. This type of change is often associated with contact metamorphism, which occurs when hot igneous intrusions, such as magma, heat the surrounding rocks.12

The term "pyrometamorphic" describes something produced by or relating to pyrometamorphism. These alterations can happen in zones around these intrusions, known as contact aureoles, and the extent of the change depends on the size and heat of the igneous body.32
