In an attempt to assess the feasibility of a future programme of seismic reflection profiling to investigate major structural features deep within the crust of Britain, existing commercial offshore data across shallow basement have been investigated together with lines on land, fired conventionally with explosives, in which record lengths have been extended to at least 12 s two-way time. Profiles crossing Lewisian basement, a granite batholith, and Caledonian and Variscan structures have been examined. The seismic information has been combined with gravity and magnetic surveys, bore-hole logs and surface geology to give self-consistent interpretational models. Features such as intrusive bodies and thrust faults can be discerned within the basement. These are clearly visible on the seismic record section obtained along the MOIST line, fired along the north coast of Scotland especially for deep reflections, and, for the first time, normal-incidence reflections from the Moho are clearly observed.
