<p>The IGCP 509 project is collating global information for the Palaeoproterozoic era through the activities of numerous international
collaborators. A database system (StratDB) and web interface has been designed to facilitate this process with links to an
existing geochronology database (DateView). As a result, all information captured will remain available in a digital format
for future researchers. The philosophy and design of the database and some of the outputs available from it are described.
One of the principal features of the system is that it facilitates the construction of time–space correlation charts using
an innovative application of GIS technology to non-geographic information, which permits users to query a variety of attribute
information associated with lithostratigraphic units, metamorphic and deformation episodes associated with user-selected tectonic
domains, large igneous provinces and major ore deposits. In the process, much of the manual labour normally associated with
the construction of such charts in standard graphical or drafting packages is avoided. Associations between units, deformation,
metamorphism, large igneous provinces and ore deposits may become more apparent once linked information is available for querying
and investigation. Geochronological information from the DateView database may also be linked to entities stored in StratDB.
GIS maps may be linked to the attribute information in StratDB and DateView to construct a variety of time-slice maps or palaeogeographic
reconstructions with the same symbology as is used in the time–space correlation charts. This database system will facilitate
the dissemination of lithostratigraphic information for many countries to a broader community and will help non-specialists
to easily view information for various Palaeoproterozoic tectonic domains. The system is illustrated using a preliminary compilation
of information for the Palaeoproterozoic of southern Africa. The correlation charts and time-slice maps provide insights to
the geological evolution of this region which emphasize some aspects and correlations which have not previously been extensively
considered; for instance, possible correlation of units in the central and western zones of the Limpopo Belt (South Africa,
Zimbabwe and Botswana) with the Magondi Belt of Zimbabwe and its extension into northern Botswana.
