Synopsis Many varieties of mineral deposit have been exploited in the Southwest of England. These include deposits which have been worked primarily for one or more of the following:- tin, tungsten, copper, lead, zinc, iron, manganese, arsenic, cobalt, uranium, pyrite, arsenic and barite. From an economic point of view the copper and tin producers collectively have proved to be by far the most important.
A summary is presented of our present knowledge of the nature and distribution of the mineral deposits and the spatial and temporal relationships between these and the igneous rocks, particularly the granitoids.
Finds of mineral deposits based on chance, on quasi-scientific techniques and on scientific ones are noted and the evolution of the science-based aids to mineral exploration is traced in some detail. It is pointed out that particularly since 1945 great strides have been made in the development of aids to mineral exploration. But although these aids have been used to varying degrees, and have proved to be of great use, the advantages accruing from their availability have to some appreciable extent been nullified by the increasing limitation of ground available for mining. This limitation is largely due to the need to preserve the environment. The common difficulty of establishing mineral ownership also militates against mineral exploration in Cornwall and Devon.
