igneous

[ˈɪɡniəs ]

Definition

Context #1 | Adjective

rock type

Igneous refers to a type of rock that is formed through the cooling and solidification of magma or lava. This process can occur either beneath the Earth's surface, where the rock is termed 'intrusive' or 'plutonic,' or on the surface, where it is known as 'extrusive' or 'volcanic.' Igneous rocks are characterized by their crystalline texture, which differs depending on the rate of cooling. Common examples of igneous rocks include granite, basalt, and pumice. The properties of igneous rocks make them vital in various geological processes and construction.

Synonyms

crystalline, magma-derived, volcanic.

Examples of usage

  • Granite is an igneous rock used in countertops.
  • The volcanic eruption created new igneous formations.
  • Many geological studies focus on igneous activity.
  • Igneous rocks provide insights into the Earth's mantle.
  • The texture of igneous rocks can vary significantly.

Origin of 'igneous'

The term 'igneous' comes from the Latin word 'igneus,' meaning 'of fire.' This etymology reflects the fact that igneous rocks are formed from molten materials. The study of igneous rocks dates back to ancient civilizations, where understanding volcanic activity was crucial for survival and land use. Scientists and geologists began systematically classifying rocks in the 19th century, with igneous rocks being a primary focus due to their significant role in the Earth's structure. The differentiation between intrusive and extrusive igneous rocks was established to better understand their formation processes, contributing to modern geological theories.
