उदाहरण वाक्य
- Glassy pillow lava is found at the seamounts, a type of rock typically formed when basaltic lava emerges from a submarine volcanic vent.
- Kjerringberget partly consists of green rocks formed when subterranean magma solidified after flowing out and coming into contact with water, forming pillow lavas.
- A further sampling cruise by the United States Geological Survey ( USGS ) recovered pillow lava and hyaloclastite from 4 of the 8 volcanoes.
- The sulfide ore occurs at the same stratigraphic level as the Lower and Upper pillow lava contact, and is overlain by unmineralised lavas.
- The volcano's landform is now gone but some of volcanic rocks are preserved in the area, including pillow lavas, and breccia.
- There are pillow lavas in the Northwest Territories that are about 2.6 billion years old and are preserved in the Cameron River Volcanic Belt.
- These include the Amitsoq Tonalite-Trondhjemite-Granodiorite ( TTG ) orthogneisses, pillow lavas and pillow breccias, banded iron formations, granodiorites, and metasedimentary rocks.
- Geochemical results of pillow lavas and chill boundaries along five transects across the volcanic belt suggest the existence of three chemically different magma types within the Bravo Lake Formation.
- Filling spaces in between the pillows in the pillow lava units are dispersed metal oxide sediments that can also be seen as carbonates, volcanic glass and pelagic sediments.
- Underwater fissural eruptions originated from the pillow lava, which are produced by the rapid cooling of the magma when it comes in contact with water, obtaining their peculiar shape.
