Autometasomatism is a term used in geology to describe a process of rock alteration caused by the migration of fluids within the rock itself. This process can lead to changes in the mineralogy and texture of the rock, and can have important implications for the interpretation of geological history.
Definitions
Autometasomatism is defined as a process of mineralogical and textural change in a rock due to the migration of fluids within the rock itself. This process can occur in a variety of geological settings, including hydrothermal systems, contact metamorphism, and regional metamorphism.
Origin
The term autometasomatism comes from the Greek words “auto”, meaning self, “meta”, meaning change, and “soma”, meaning body. The term was first used in the early 20th century to describe a process of rock alteration that was distinct from other forms of metamorphism.
Meaning in different dictionaries
Autometasomatism is not a term that is commonly found in dictionaries. However, it is often used in scientific literature to describe a specific type of rock alteration.
Associations
Autometasomatism is associated with a variety of geological processes, including hydrothermal alteration, contact metamorphism, and regional metamorphism. It can also be associated with the formation of mineral deposits, such as gold, silver, and copper.

The root words of autometasomatism are “auto”, meaning self, “meta”, meaning change, and “soma”, meaning body. These words are also found in other scientific terms, such as autophagy, metamorphism, and somatic cells.
Example Sentences
- The rocks in this area have undergone extensive autometasomatism due to the presence of hydrothermal fluids.
- The mineralogy of this deposit is the result of autometasomatism during regional metamorphism.
- The texture of this rock has been altered by autometasomatism, resulting in a distinctive banded appearance.
