The aim of the international field course is to introduce participants to the recognition and understanding of spatial and temporal patterns of hydrothermal fluid-rock interaction in magmatic and sedimentary environments.

The course starts with introductory lectures on mineralogical and geochemical aspects of hydrothermal fluid-rock interaction and to the regional geology, hydrogeology and economic geology of areas visited.

During the following four days, the course will examine outcrops of hydrothermal systems in Tertiary volcanic and Mesozoic-Tertiary volcanic and sedimentary units in the volcanic belts of Hungary, as well as thermal karst and warm spring areas of the Buda Hills.

The course is recommended to MSc and PhD students, as well as early carrier scientists interested in mineralogy, geochemistry, hydrogeology and economic geology.

The field program requires general fitness for fieldwork.

Field accommodations will be provided in double or shared rooms, transportations by bus. The total travel lengths are about 1000 km.


The maximum number of participants is 20.

Applications for participation in the field course are accepted on the basis of the order of registrations.
