Metamorphism Meaning: Definition, Examples, and Translations

🪨
Add to dictionary

metamorphism

[ˌmɛtəˈmɔrfɪzəm ]

Definition

Context #1 | Noun

geological process

Metamorphism is a geological process that involves the alteration of the mineralogical composition and structure of rocks due to changes in temperature, pressure, and chemically active fluids. This process can transform igneous rocks into metamorphic rocks and can significantly influence the physical properties of the original rock. Different types of metamorphism include contact metamorphism, which occurs due to heat from molten magma, and regional metamorphism, which occurs over large areas under elevated pressure and temperature conditions. Understanding metamorphism is essential for studies in geology and tectonics.

Synonyms

alteration, change, transformation.

Examples of usage

  • Metamorphism alters the original rock's texture.
  • Contact metamorphism occurs near magma.
  • Pressure and temperature drive regional metamorphism.

Origin of 'metamorphism'

The term 'metamorphism' is derived from the Greek words 'meta' meaning 'beyond' or 'change' and 'morphe' meaning 'form' or 'shape'. The concept of metamorphism has its roots in the early studies of geology in the 19th century, where scientists began to understand the processes by which rocks change over time. Over the years, the idea evolved with advances in mineralogy and petrology, leading to a deeper understanding of the physical and chemical conditions that influence rock formation. Today, metamorphism is a fundamental concept in geology, offering insights into the Earth's processes and the history of its crust.
