Definition of igneous in English: igneousadjective ˈɪɡnɪəsˈiɡniəs Geology 1(of rock) having solidified from lava or magma. 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 Relating to or involving volcanic or plutonic processes.
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.
- 1.2rare Of fire; fiery.
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.
