Abstract

Studies on fluid inclusion planes of quartz from granite and pegmatite revealed that hydrothermal fluids related to Palaeogene andesitic volcanism penetrated the Variscan intrusion. Comparison of field observations on faults and joints with orientation of fluid inclusion planes revealed that the development of fractures in granite had taken place under rather similar orientations of palaeo-stress field both in Variscan and Alpine times and therefore many fractures of granite may have re-opened during the Palaeogene events. The common stress orientations are NW-SE and E-W. NE-SW orientation is characteristic to Palaeogene fluid inclusion planes only, whereas N-S oriented fluid inclusion planes are related to Variscan events only. Results also suggest that intense syn-volcanic faulting took place during the Palaeogene igneous activity, and therefore the same volume of Variscan granite was affected by both subvolcanic-type and epithermal type Tertiary fluids.
