Abstract:We utilize the technology of high-resolution multiple coverage reflected wave method combined with first-arrival travel-time tomography inversion in one potential site for high-level radioactive waste disposal, at Alxa, Inner Mongolia. Two seismic profiles, whose total length is about 27 kilometres, are carried out across the target rock. The results of seismic detection reveal the spatial distribution, the south side unconformity boundary, and the rock’s inner structure, especially the internal faults, of the target rock. The fault structures and non-conforming strata contact relations in the interior of the mesozoic-cenozoic basin, which are located on the south of the target rock, also are clearly reflected. The seismic exploration work with large high-velocity rock as detecting target is infrequent.
