f Shallow fault location in coal measures using offset wenner resistivity profiling

A region within the Westphalian Lower Coal Measures of the Midland Valley of Scotland is currently under consideration as a site for open-cast mining. Mining will only be viable to one side of a fault running through the region and drilling to determine the exact position of the fault is not possible. A technique employtng nondestructlve surface measurements will therefore have to be used for precise fault location. The coal measures are overlain by 10-20m of boulder clay above which lies peat which has been worked commercially.
