Summary

The significance of water-filled fracture zones and the procedures for mapping these features are outlined. Relevent geophysical methods and their applications and limitations to this problems are discussed more fully. A case history of geophysical mapping at Mochudi in the Botswana Republic is given to illustrate the field procedures for electrical resistivity and magnetic methods and the presentation of the results.

Résumé

On décrit sommairement la signification des zones de fractures emplies d'eau et les procédés pour les cartographier. On discute plus complètement des méthodes géophysiques utiles à ce problème, avec leurs applications et leurs limitations. On donne un exemple de levé de carte géophysique effectué à Mochudi (Botswana) pour illustrer la marche à suivre sur le terrain pour la résistivité électrique, la méthode magnétique et la présentation des résultats.
