单词 seismic refraction
释义

Definition of seismic refraction in English:

seismic refraction

noun
mass nounGeology
  • The refraction of elastic waves on passing between formations of rock having different seismic velocities.

    Example sentencesExamples
    • Large amounts of seismic refraction and reflection data have greatly improved knowledge of the crustal structure along the outer Voring Basin and the Voring Marginal High.
    • Gravity and seismic refraction studies have shown that segments tend to have the thickest crust (about 8 km at slow-spreading ridges) at their centres and thin crust at their ends.
    • However, a number of seismic packages are recognizable in the offshore Palaeozoic succession and in some cases correlate with velocity units identified by seismic refraction surveys.
    • It extends upwards from a depth of about 6 km, at which depth Precambrian crystalline basement is predicted from seismic refraction studies.
    • The sedimentary basin architecture has been extensively mapped using seismic reflection profiles, and the nature of the crust has been probed with seismic refraction data.
