| Abstract |
Ancient (pre-Cainozoic) geothermal activity can be recognised by remnants of silica sinter, manganese and iron oxide deposits, alteration assemblages and hydrothermal eruption breccias. Examples of each of these are found in north-east Scotland, frequently on or near the intersection of major faults and lineaments. They are all probably the product of Early Devonian geothermal activity which appears to have been widespread in north-east Scotland at this time. Six potential gold prospects are identified in the region. |
