Seismic Imaging of Lower Crustal Heterogeneity

  • Richard W. Hobbs

Abstract

Both national and international programs have been actively collecting seismic reflection data from the lower crust and upper mantle for the past three decades. Surveys have been conducted over a variety of targets from the highest plateau to the deepest oceans and much has been learnt about the structure of the lithosphere and how that structure relates to the dynamic processes that shape the Earth’s surface. Technical advances in survey design and data processing have improved the reflection image. However, good survey practice does not always guarantee a usable result. Some of the issues associated with how data are acquired and processed and how these interact with imaging the heterogeneity in the crust are explored in this chapter.
