Popis:	The refraction method of seismic exploration was initiated in 1952 in the Northern Sahara after several difficulties were encountered with the reflection method. The first tests showed the existence of a deeper marker bed having a velocity of about 6,000 m/sec (20,000 ft/sec) which later proved to be the eroded surface of the basement. Now refraction can be employed, at least in certain regions, in detailed surveys although many difficulties in interpretation still exist. Both field practices and methods of interpretation are discussed.
