The basic activities at the Division of Geological Mapping
Ever since the foundation of the Geological Institute of Hungary the geological mapping of the country is one of the most important basic activities. This leads to the edition and publishing of geological maps. Within the Division of Geological Mapping there are two organisational units doing field mapping and one unit dealing with methodological research.
The principal task of Mountain Geology as well as of Lowland Geology is the edition of geological maps in/of various scales based on geological field mapping. The scales of the maps are determined by the complexity of the geological structure of the area depicted and the scope of their usage. The scale of sheets for fieldwork is 1:10 000, the scale of the compiled geological maps is 1:25 000 in the mountainous areas. The regional geological maps are published generally in scale 1:50 000 (in case of more complex areas the printed maps might be more detailed). In case of plains fieldwork is carried out in scale 1:25 000, compilation in scale 1:50 000, publishing of map sheets in scale 1:100 000. From the point of view of later potential utilisation the compilation of detailed special versions of map sheets depicting directly basic data is an important task as well, first of all with regard to meeting the aims of applied geological researches (hydrogeology, engineering geology, research of mineral resources, environmental and nature protection etc.). The geological maps published are provided with descriptions and explanatory texts.
The methodological task of the Maps and Databases is the building and development of national map and borehole database, and the organisation of completing and maintenance of it, as well as the elaboration of principles of compilation of geological maps.
The regional geological maps of Balaton Highland, Velence Hills and Bükk Mountains prepared with the co-operation of the researchers of the Division of Geological Mapping have been recently published. Presently the field mapping of Vértes and Gerecse Hills, Mezőföld and the western forelands of the Bükk Mountains, as well as the editing of the geological maps of Mecsek and Villány Mountains are in progress.
