Abstract

Refraction seismic data with a dense receiver and source spacing were acquired at the future site for the Swedish repository for spent nuclear fuel. Data were recorded on two lines simultaneously, allowing some 3D information to be obtained. Reflection seismic processing of the refraction seismic data reveals a sub-horizontal reflection at about 20-25 ms (c. 60 m) that can be traced under much of the survey area.
