Wiechert-Herglotz inversion as integration on a closed contour

GEORGE A. MCMECHAN

PACIFIC GEOSCIENCE CENTRE EARTH PHYSICS BRANCH, SIDNEY, BRITISH COLUMBIA, Canada

Abstract

Wiechert-Herglotz integration around the boundary of the p-{delta} area representing the {tau} contribution of a ray segment gives the corresponding depth increment. Thus, Wiechert-Herglotz inversion can be performed with reference depths other than the surface of the Earth and with nonsurface as well as surface focus p-{Delta} curves providing that a depth can be assigned to any point on the path of integration.
