GeoReM (Geological and Environmental Reference Materials), a database of reference materials of geological and environmental interest, is accessible to the scientific community on the internet. The database was developed at the Max Planck Institute for Chemistry[1] in Mainz by Klaus Peter Jochum et al. (2005)[2] and contains published analytical, compiled, and certified values for major and trace element mass fractions and concentrations as well as radiogenic and stable isotope ratios.[3][4] Important metadata about the analytical values (uncertainty, type of uncertainty, method, and laboratory) are given as well as information about sample type, producer, and references.[5]
Currently (state: January 2017) GeoReM contains c. 3200 reference materials and about 40 500 analyses from 8 900 publications and provides access for geochemists to information about reference materials important for their research.[6] The structure of GeoReM is similar to that of the databases for rocks from oceanic islands, island arcs, continents (GEOROC),[7] ocean floor (PetDB),[8] and the western North America (NAVDAT).[9] GeoReM offers six different search strategies:[10]
- Samples or materials (published values): Ranges and tables of analytical data with the corresponding metadata are provided for all the reference materials together with sample information such as origin, availability, and reference.
- Samples (GeoReM preferred values): Currently, preferred values for 44 frequently requested reference materials are given (published certified values and reference values as evaluated by the GeoReM team)
- Chemical criteria: Elements and isotope ratios can be selected and the search can be refined by minimum and maximum concentration values, matrices, and physical forms as well as by laboratories and methods.
- Chemical criteria based on bibliography: All element concentration and isotope data published in a special year by a certain author in a selected journal can be listed.
- Bibliography: It is possible to search by author/coauthor, by journal, by GeoReM number, and by keywords.
- Methods and institutions: Methods used in selected institutions and institutions using certain techniques can be listed.
