TECHNIQUE DE MESURE ET D'INTERPRETATION MINIMISANT LES ERREURS DE MESURES EN MICROGRAVIMETRIE*

Different sources of error influence gavity surveys, particularly shallow “micrograuity” sur‐veys. Experiments show that. the most frequent source of error in gravimetric prospecting is bad estimation of drift. Better control of drift exists with the field procedure and interpretation technique developed by the authors, as can be shown theoretically as well as experimentally. The method implies a random or semi‐random spatial sequence of measurement points. A real case of field prospecting is described.
