Abstract
Sub-sill seismic imaging is a current exploration challenge, ranging from detection to the impact on deeper imaging. Limited studies have been undertaken as to understand these issues. Here we present new results using constrained models of intrusions and full-waveform seismic modelling techniques to better understand the wave propagation processes, specifically focusing on the causes of reduced imaging. A significant amount of primary energy is lost to refractions, conversions and interbed multiples, however, unlike extrusive basalt, scattering and the associated rapid attenuation of all but the lowest frequency signal is not the significant problem.
