adjective ˈɪɡnɪəsˈiɡniəs

Geology

1(of rock) having solidified from lava or magma.
〔地质〕（岩石）火成的
Example sentencesExamples
- This heat gradually accumulates and eventually causes localized eruptions of basaltic magmas (molten igneous rock).
- Major crustal rifting has also played a part in the evolution of large bodies of Proterozoic sedimentary and igneous rocks.
- The occurrence of these felsic extrusive igneous rocks potentially provides key information on the complex interplay of magmatism and tectonics.
- The prevalence of Late Jurassic subduction-related igneous rocks indicates that arc formation and accretion orogeny were the most important processes during the evolution of this part of the Internal Hellenides.
- Below the lowest sheet of largely coherent mafic igneous rocks is the Phyllite-Quartzite Group, a sequence of turbidites and black mudrocks.
1. 1.1 Relating to or involving volcanic or plutonic processes.
  （与）火山爆发（有关）的；（与）火成（有关）的
  igneous activity
  火山活动。
  Example sentencesExamples
  Rhyme, in particular, lay on a major NE-trending fault and local igneous activity may have provided the energy to sustain the hot springs.
  By the Early Devonian the Iapetus Ocean had closed and was replaced in northern Britain by an essentially transtensional regime with sinistral shearing, and accompanied by major igneous activity.
  The layering in these ultramafic rocks, and their position above mantle tectonites, is attributed to lower crustal igneous processes.
  On Macquarie Island there's very similar kind of geology, as I'm sure Rick has described; we have mantle rocks and evidence of punctuated deformation events in igneous activity.
  However, enormous emphasis has been placed on them for understanding igneous processes and the evolution of Earth.
2. 1.2rare Of fire; fiery.
  〈罕〉火的
  Example sentencesExamples
  It is an igneous or fiery aura, not indeed in the open act of combustion, but composed of the finest and most minute particles of a peculiar species of elementary fire.
