ABSTRACT
In a book focused largely on map problems and their solutions, many aspects of economic geology and geotechnics must be left to other textbooks. However, the reader should appreciate that problems in both these fields are dependent upon the analysis of geological structures and in many cases economic calculations and design decisions are made on data derived from geological maps. We have seen the simplest application of an economic problem already in Map 10, the deduction of the position of the sub-unconformity ‘outcrop’ of a coal seam from structure contour intersections. Simple economic problems were also posed on Maps 20 and 21.
