Abstract

Th is paper presents the results of geophysical mapping of buried relief in the Hranice karst, central Moravia, by electrical resisti vity tomography (ERT). Geophysical data were compared with borehole database and interpretations of Hranice karst morphology (published data). Th ree measurement areas were selected SE of the city of Hranice close to prominent limestone outcrops and expected buried karst phenomena. Fourteen 2D resistivity profi les were measured by ARES system using the Wenner-Schlumberger array. Th e ERT proved to be very useful due to contrasting resistivities between the limestone and the clayey cover sediments. Our data support the idea of pre-Miocene tropical karstifi cation published by previous authors.
