metasomatism
This term is a highly specialized technical word used almost exclusively within the fields of geology and geochemistry. It describes a specific process of chemical exchange where fluids migrate through solid rock, altering its composition without the rock ever reaching a liquid state. This distinguishes it from magmatic processes where melting occurs.
As a technical scientific term, it is treated as an uncountable noun. It refers to the phenomenon or the process itself rather than a discrete event that can be counted. In academic writing, it is frequently paired with adjectives describing the type of fluid involved or the resulting mineral assemblage.
