The application of approximate rules, whereby apparent resistivity space sections for two dimensional structures can be composited from spaces derived for elementary features is extended to a complex example drawn from a field survey over a fluorite mineral vein.
A quantitative solution for the observed resistivity space is presented and the computational sequence involved in matching the observed space is given in detail.
The interpreted results are examined in relation to the known geology, supplemented by the results of excavation, and to model tests conducted using a tank analogue.
The example also illustrates how successive compositions can be employed in estimating the form of resistivity space in a relatively complex situation.
