Summary:The patterns of magmatism and mineralization in SW England are described. It is shown that the distinct types of textures in the hypothermal lodes exposed in and around the granite plutons of the Cornubian batholith can be related to the mechanisms governing fluid flow and mineral growth in the hydrothermal systems at different stages of their paragenetic evolution. It must be concluded that fluids of direct magmatic origin, or fluids equilibrated with granite at near-solidus or sub-solidus temperatures, were chiefly responsible for the parageneses and textures observed. The driving energy was principally PΔV expansive work originating from the hydrous residue in the crystallizing granite magma, the collection or escape of which was regulated seismically by interaction with the field of regional stress.
