Looking through a microscope is a typical activity of many geoscientists as minuscule details reveal the history of rocks. Microfossils or even smaller nannofossils represent the remains of animal or plant organisms. Micropalaeontologists use them for dating the relative age and former sedimentary environment of rocks. Information on water depth, salinity or climate at the time of deposition can thus be gained.
Economic geologists, hydrogeologists and engineering geologists representthe applied geosciences. Their task is to evaluate occurrencesof raw materials or groundwater and to assess slope stability. GBAundertakes assessments of the geo-potential of a region in the overlappingfields of resource planning, environmental protection, landuse or groundwater supply.
Geological maps form the most important basis for almost any geoscientific problem. The coloured display of the distribution of rock units on topographic maps accompanied by special symbols and line elements portray the orientation of these units in space. Information on rock age and composition together with the location of quarries and land slides complement the map.
GBA's mandate to serve the government as the centre for informationand advice in the field of geosciences is written into the law (FOG§ 18). Furthermore, the website provides access to data and informationanywhere and anytime.
