Abstract Title: Constraining Lithospheric Structure with Teleseismic Scattered Phases Abstract Author(s): Wilson, Charlie (Stanford University) Abstract: Using teleseismic scattered phases to determine crustal and upper mantle structure has become common over the last ten years. Recent application of more sophisticated techniques invloving array processing have produced more reliable and higher resolution images thereby making analysis of teleseismic scattered waves an important tool in regional scale tectonic studies. However, image artifacts introduced by coarse station spacing, velocity uncertainties, and processing assumptions may lead to misleading images. I present some successes, pitfalls, along with recent advances of teleseismic imaging to provide a realistic depiction of its capabilities and possible application to the development of the Great Basin.
