Geophysics Review Topical Report: Application of Seismic Tomographic and MagneticMethods to Issues in Basaltic Volcanism

摘要

The objectives of this investigation are to review the application of geophysicalmethods in use in the Yucca Mountain Region (YMR) as part of site characterization, discuss the application of these methods in the context of volcanism studies, and explore the utility and limitations of geophysical methods in volcanism studies through presentation of parametric models and the results of numerical experiments. In the context of volcanism studies in the YMR, geophyisical methods have, to date, been used primarily in the exploration for volcanic features that lack surface expression. This has included the use of broadband seismic tomographic methods to characterize the velocity structure of basaltic source regions in the mantle and aeromagnetic and ground magnetic surveys to search for buried basaltic centers in the Amargosa Valley.
