The work was done in three distinct locations in the quarry: on the land surface above the quarry, along a road crossing the quarry, and in front or below the active quarry face. The results led to the definition of planes of structural discontinuity extending to 25 m depth, including inclined fractures and low-angle unloading joints; as well ...

Geophysical modeling provides generalized and non-unique solutions to questions concerning the geometry of subsurface geologic relations. The non-uniqueness of these solutions is both a mathematical problem and one related to the multiplicity of sources that can cause geophysical anomalies. This feature is an implicit uncertainty

, the most common geophysical methods employed in mineral exploration are electrical, electromagnetic, gravimetric, magnetic and seismic. Shallow geophysics, for example, is used for the investigation of geological structures with small dimensions at the top of the crust. Currently, shallow geophysics is frequently used in mining [19,20].

1.6 The Survey Area is underlain by Middle Devonian Limestone; exposures in the quarry face show a local strike of 126 degrees, with a southerly dip of 10 degrees. The roughly orthogonal jointing pattern would seem to be oriented with the strike, giving boxwork 'grikes' at the contact with overlying unconsolidated sediments.
