hidden layer


Show Summary Details

Quick Reference

A layer whose presence remains undetected by seismic refraction methods because (a) it is too thin and has insufficient velocity contrast to provide a discernible arrival; or (b) it is of lower velocity than the overlying medium. The term is analogous to the suppressed layer in the interpretation of electrical resistivity soundings.

(a) it is too thin and has insufficient velocity contrast to provide a discernible arrival; or (b) it is of lower velocity than the overlying medium.
