Geophysical Imagery of Small-Scale Fracturing

Insufficient knowledge of fractured rock represents a common problem in many fields of the Earth Sciences such as the environment, storage, hydrogeology, etc. The study presented here was undertaken in ornamental stone quarries, which offers the main advantage of being able to verify geophysical interpretation after cutting of the working face (meso-scale) or the blocks (micro-scale). As far as the meso-scale is concerned, the aim is to make an inventory of fracturen of an order of approximately 1 m in length, whereas for the micro-scale, it is to identify fractures of up to ten centimetres.
