In order to achieve the project aim and objectives G-BASE works
to the following principles:
- A high level of quality control throughout project activities
ensures a geochemistry database of uniformly high quality that
has the confidence of end users.
- Information about the geochemical baselines of the UK surface
environment is achieved by the collection of a wide variety of
sample media including stream sediments, panned concentrates, surface
and profile soils and stream waters.
- The project is principally concerned with natural geochemical
baselines looking at regional trends rather than site specific
- The regional geochemical baseline is of particular importance
in urban areas and in these areas soil sampling is undertaken at
a greater density.
- The project supports research that demonstrates the variety of
ways G-BASE results and samples can be used.
- Sample analyses are principally concerned with the inorganic
elements and the physio-chemical parameters that may affect their
distribution (such as Eh, pH and organic carbon content).
- The project does not monitor variations over a period of time.
It is concerned with creating a 'snap shot' record of the geochemical
nature of our environment against which future generations can
measure and monitor changes.
- The project supports national and international working groups
devoted to the standardisation of geochemical mapping procedures
and the development of a global geochemical database.
- The project seeks to provide the user community with a readily
accessible and well described geochemical database of the UK surface
- The project assists other governments around the world wishing
to develop national geochemical mapping programmes.
