3-D Multi-Component Shearwave Seismic – A New Tool for Near Surface Prospecting?

B029 3-D MULTI-COMPONENT SHEARWAVE SEISMIC – A NEW TOOL FOR NEAR SURFACE PROSPECTING? Summary 1 We present a “true” 3-D shearwave refraction survey of an archaeological site in western Turkey performed for near surface basement mapping in a 1*1 m precision. Data were acquired in both three geophone and three shot components showing spectacular effects of wave propagation. Special wavefront processing and decomposition techniques were developed in order to handle effects of strong basement topography and refraction sideswipe. Introduction Geophysical work in the alluvial sedimentary environment of the archaeological site in Miletus' Lions' Harbour (Turkey) raised the question whether prominent
