  • It is useful in dating ocean sediment cores and subaerially erupted volcanics.
  • If they have accumulated subaerially, like the ash beds found on Mt.
  • Vesicular textures are up to 5 %, suggesting that the lava erupted subaerially.
  • This is also subaerially exposed, but is flooded twice a month by spring tides.
  • This is the only place on the planet where such a triple junction in oceanic crust is exposed subaerially.
  • It is subject to tidal shifts, which means that it is subaerially exposed once or twice a day.
  • If the volcano breaches the surface of the glacier it will be topped by a subaerially erupted lava plateau.
  • The sandstones of its lower member are also quite weathered and, thus, appear to have accumulated subaerially.
  • This means that the strata of the uppermost John Henry Member were subaerially exposed and eroded before Drip Tank deposition.
  • However, if significant amounts of lava are later erupted subaerially, then the volcano may assume a more conventional shape.
  • Features, such as the presence of coal beds and desiccation cracks, suggest that parts of the unit were deposited subaerially.
  • Such coasts are characterised by a subaerially formed relief that has previously experienced little deformation by littoral ( tidal ) processes, because the sea level, which had fallen by more than 100 metres during the last glacial period, did not reach its current level until about 6, 000 years ago.
  • Ash Mountain at the head of Parallel Creek consists of pillow lava and hyaloclastite, South Tuya consists of loose volcanic debris with basaltic dikes intruding into the volcano and Tuya Butte and Mathews Tuya consist of pillow lava and hyaloclastite on its lower flanks with subaerially erupted lava flows at their flat-topped summits.
