Topic of the month

Geology Portal

Themes	Description
Anthropogenic pollution	The most diverse bedrock and rock components have weathered to fertile soils over thousands of years. They constitute the indispensable foundation for the terrestrial ecosystem, for plant growth and higher forms of life. The Swiss Soil Monitoring Network NABO monitors the state and development of soil pollution and is an important instrument in preventative soil protection.
Applications	All of us are confronted daily – often unknowingly – confronted with geology: from the ground on which we live, past the concrete as part of a building’s foundation, to the copper in the mobile telephone, so much has to do with geology.

Themes	Description
Boreholes	Boreholes provide information about the composition of the ground. They also serve a particular purpose: for example, for the production of natural gas or as preparation for construction methods.
Bergregal	The Bergregal (principles of mining law) regulates the property rights for mineral resources. In Switzerland, it is mostly determined by the cantons. Energy and ore resources as well as salt are usually included therein.
Borehole data model	As a result of greater and more diverse utilization of the subsurface, administrative and public circles are increasingly focusing on our knowledge about the subsurface. Borehole data from drilling operations are one of the main sources of the relevant information. Therefore the Swiss Geological Survey, in collaboration with representatives from the federal government, cantons, private sector and universities, developed the “borehole data model" as the first recommendation for structuring basic digital borehole data.

Themes	Description
Construction site	The construction site is to be evaluated, described and investigated in detail for the professional execution of construction projects.
Construction & technology
CO2 sequestration	With CO2 capture and sequestration, carbon dioxide is separated from combustion exhaust gases and subsequently indefinitely stored without using containers, in deep underground rock layers. The technology is currently still in the developmental stage.
Culture	Dimension stone as building material, utensils and carriers of messages are part of our culture: the oldest cultural artifacts are similarly from stone, just as the products of today’s artists or engineers.

Themes	Description
Deep repository	In Switzerland, radioactive waste will in the future be disposed of in deep geological repositories. These are situated located several hundred meters below the surface of the Earth in geologically stable rock layers. Geodata documents the federal governments sectoral plan procedure.
Data viewers	Is the Evolène map sheet already printed? On what type of ground is my house standing? Can I find public borehole data there? You can find the answer to these and other questions in the two data viewers «map.geo.admin.ch» and «swissgeol.ch».
Data models	In general, a model depicts the very complex reality. In order to enable this depiction, the reality must be generalized and idealized.

Themes	Description
Energy supply	Switzerland’s energy supply results largely from the import of fossil fuels. To reduce her CO2 emissions and become more independent on foreign countries, Switzerland must rely on energy efficiency and renewable energies. Geothermal energy could play a decisive role in this process as a geological energy source.
Energy
Energy resources	Switzerland has a high per capita consumption of energy resources. Its energy requirements are covered by various sources: fossil fuels such as combustibles and motor fuels make up the largest portion thereof.
Earthquakes	Earthquakes are caused by stresses in the Earth’s interior which built up by the movement of the Earth’s crustal plates relative to one another. If these stresses become too large then a fracture occurs, whereby the rock masses suddenly jerkily move past each other.
Experience Geology	For more geo-topics among the general public!
Experience	Whether for children or adults: museums, show mines, geoparks or geological trails offer numerous opportunities to be inspired by geology. Here you will find a selection of what is on offer.

Themes	Description
Fundamentals of geology

Themes	Description
Groundwater	Groundwater is an important indigenous resource. It is a central element of the natural water cycle and feeds valuable habitats. An integral groundwater conservation is indispensable for conservation of groundwater resources.
Geothermal energy	Geothermal energy – energy from the earth’s interior – is today already widely used in Switzerland. The potential for the future is enormous.
Geotechnics & engineering geology	Geotechnical engineering combines elements of earth science, construction and mining. Tunneling projects, slope stabilization or site investigations are typical areas of application.
Geological cartography	Geological maps display a multitude of geologically relevant information in a concise manner. They are an important basis for geotechnical and environmental decisions. .
Geophysics	Geophysics deals with all of the Earth’s relevant physical phenomena. It includes various fields and can be subdivided according to research methods and their relevant applications.
Geological hazards
Geology in everyday life
Geology data model	The geology data model forms the foundation for national uniformly structured geological vector data sets.
Geology lexicon	Numerous databases and lexica about geology can be found in the internet and in book form.
Geotopes	Geotopes are natural geoscientific monuments worthy of protection: spatially constrained parts of the geosphere of geological, geomorphological or geo-ecological importance. Depending on whether the formative processes are complete or still in progress, they are then static or active geotopes.
Geological hiking trails	Geotourism develops, promotes and commercializes special geological landscape features. Professionals and lay people can experience and understand developments in earth science on geological trails, in geoparks, show caves, geotopes or at events such as “Erlebnis Geologie”.

Themes	Description
Hydrology	Water shapes the character of landscapes and natural ecosystems. It is a significant basic need for the population and for numerous economic sectors in Switzerland. Hydrological data allow observation of the water balance.
Health	Radon and asbestos represent two health hazards that are associated with geology.

Themes	Description
Industrial minerals	Industrial minerals are minerals or rocks that are important for technical processes and applications in industry. Unlike ores, which are converted into metals by smelting, industrial minerals can be used in their natural state or after minimal beneficiation.

Themes	Description
Quaternary geology	The Quaternary is the most recent period in the Earth’s history: the last 2.6 million years. It is marked by the appearance of man as well as repeated glacial/interglacial cycles, which strongly influenced the mountains and their environment.

Themes	Description
Rockfall, landslides, debris flows	Mass movements (gravitational natural hazards) are downslope directed displacements of solid and/or loose rocks as well as soil material. As falling processes, they can occur quickly and suddenly. Landslides on the other hand, are slow, continuous processes.
Rocks & soils	The rocks and soils are an important commodity group for Switzerland. This includes raw materials for the brick-and-tile industry, lime and marl for the binder material industry, gravels and sands as well as dimension stone and rock for construction purposes.
