The geoarchaeological collection of IPAS (Integrative Prehistory and Archaeological Science) at the University of Basel and of AMGC (Archaeology, Environmental Changes & Geo-Chemistry) at the Vrije Universiteit Brussel includes block and sediment samples of soils and archaeological deposits as well as rocks, flints, ceramics and mortar samples etc. The „I-GEOARCHive“ image database of thin section scans (and corresponding microscope photos) makes the collection digitally accessible to the public and in particular to research and teaching. The freely accessible „I-GEOARCHive“ database enables users to keyword, analyse, publish and archive geoarchaeological samples. Furthermore, micromorphological observations are linked to the thin section scans and thus to the block samples and profiles. This cross-linking enables multidimensional publication and archiving of micromorphological image data and their relation to original archaeological features.
