mantle rock การใช้

ประโยคมือถือ
  • It was formed from deep sea or mantle rocks.
  • Their spatial arrangement thus underlines major thrust planes bringing these mantle rocks into higher crustal levels.
  • It rises into the solid mantle rock, lowering its melting temperature and causing the rock to melt.
  • At the same time erosion resulted in stripping of the outer mantle rocks and further modeling of terrain.
  • I have examined thousands of mantle rocks in my career, but I had never seen anything like this,
  • In this model, tectonic plates diverge at mid-ocean ridges, where hot mantle rock flows upward to fill the space.
  • Debate continues whether these mantle rocks were a fluid and / or metal source, or simply reflect a favourable pathway.
  • Two types of magma have been determined to have generated in the Earth's upper mantle by partial melting of mantle rocks.
  • But if crust is recycled, the elements should be redistributed, leaving more complex chemical signatures in both mantle rocks and recycled crust.
  • Both can promote surface uplift through isostasy as hotter, less dense, mantle rocks displace cooler, denser, mantle rocks at depth in the Earth.
  • Both can promote surface uplift through isostasy as hotter, less dense, mantle rocks displace cooler, denser, mantle rocks at depth in the Earth.
  • The polar crust is unusually thin, and the new eruptions may allow unusually direct sampling of mantle rock _ a holy grail of science.
  • The Dun Mountain-Maitai Terrane includes the Early Permian ( 290-256 Ma ) Dun Mountain Ophiolite Belt, composed of mafic sea floor basalts and ultramafic mantle rocks.
  • When glaciers covering more northern latitudes melted at the end of the mantle rock out from under the Netherlands and south England : this is forebulge sinking.
  • The redistribution of ice-water on the surface of the Earth and the flow of mantle rocks causes changes in the axis, and wobble of the Earth's rotation.
  • Anderson and his collaborators investigated the relations between the behavior of mantle rock under high pressures and temperatures, phase transformations of mantle minerals, and the generation of earthquakes.
  • This is due to the gravitational attraction between the mass of the melted water and the other masses, such as remaining ice sheets, glaciers, water masses and mantle rocks
  • Also in certain sections of the region, we can find granite, which is an mantle rocks, indicating that it came from the mantle and did not mix with continental rocks.
  • These early-fractionated mantle rocks were originally capped directly by a thick mafic crust that contained the potential subsequent crustal components, including a large proportion of Earth s major heat-producing elements.
  • Petrographic research all over the world studied mantle xenoliths and it was found, they are the source rocks for basalts : the basalts are partial melts of the mantle rocks.
