Abstract

Electrical prospecting methods have been applied to the study of Holleford crater on three different occasions. The results are discussed and compared to those from previous investigations. A certain asymmetry of the crater has been established; however, it most probably concerns the Precambrian basement rather than the impact crater itself. Supplementary measurements would be required for more precision. The depth to the undisturbed basement has been deduced to be 800 m in the center of the depression. The application of electrical methods to similar structures has been considered and evaluated.
