Definition of subaerial in English:
subaerial
adjective sʌbˈɛːrɪəlˌsəbˈɛriəl
Geology Existing, occurring, or formed in the open air or on the earth's surface, not under water or underground.
Example sentencesExamples
- The presence of locally interbedded airfall tuffs implies subaerial (or at least shallow-water) eruption.
- This scenario requires that a narrow zone of marine shale deposition should occur while the rest of the basin was undergoing subaerial erosion.
- The general planar topography of the top-truncation surface of the Sahtan Group suggests that erosion mainly involved subaerial dissolution, in association with a gentle uplift of the carbonate platform edge.
- Tectonic denudation and subaerial erosion thinned and locally eliminated the hanging-wall blocks, whose detritus was incorporated into the Tectono-Sedimentary Unit basin.
- The first cycle initiated in the early Paleocene and represents a transition from Cretaceous marine turbidites and shales to subaerial fluvial sandstones and conglomerates.

adverb
Geology The volcanic pile built up above sea level so that lavas began to be erupted subaerially.
Example sentencesExamples
- It is thus apparent that the upper oolitic shoals were temporarily subaerially exposed, receiving meteoric water and probably allowing the formation of a lens of fresh water in the subsurface.
- Some external black glass is noted where the tubes may have been exposed subaerially during formation, but no exogenic specimens were noted.
- The long time during which the continental interiors had been subaerially weathered and lowered by erosion was succeeded by one of progressive flooding and coverage by shallow seas.
- The Mikis Formation consists of 380-500 m of compound lava flows, typically pahoehoe-type with ropy surfaces and oxidized flow tops, indicating that they were erupted subaerially.
