Stable isotope analyses (C, N, O and Sr) have been for a relatively long time used in geochemistry, geochronology and geology. The Strontium isotopes ratio (87Sr/86Sr) is used in geology for example for a dating of sea sediments and intrusive igneous rocks...
Teeth cementum microstructures analysis is often used for an age determination of humans and animals. The cementum grows during the entire life of an individual. The cementum growths are studied on thin sections, which are made in the first third of a tooth root. Roots...
Terrain reconnaissance combined with knowledge of topographic, geomorphological and geological data is one of the basic steps in assessing the archaeological site or possible formation processes that fundamentally influence the origin and preservation of the archaeological record...
Geochemical analysis is an integral part of quality geoarchaeological research. However, the type of the analysis depends on the specific information we want to obtain. This means that, for example, if the aim of the research is to determine the distribution of elements related to...
The sense of the petroarchaeological analysis of ceramics is to evaluate the mineralogical composition of ceramic shards in order to determine, for example, the provenance of the material used to make ceramics, reconstruction of production technologies (forming methods, firing conditions) and variations in time and...
Recently we have launched a new ERCA (Excelent Centre of Archaeomtery) web site....
Sedimentological analysis is important for a cognition of circumstances of origin, function, and termination of archaeological sites. A specific contextual analysis of sediments based on the microscopic study of the in-situ sediments, known as the soil micromorphology, is often necessary for a correct interpretation of...
In the ERCA centre it is possible to make use of the possibility of scientific determination of a raw material of polished (ground) stone tools. A first step is a macroscopic determination of a raw material with a use of the comparative collection...
Raw material determination and determination of its origin is a specific part of the analysis of chipped lithic artefacts. The origins of the lithic raw material analysis are as old as the scientific research of this type of artefacts itself...
Analysis of plant macroremains deals with separation and determination of plant macroremains (seeds, fruits, needles, buds etc.) excavated from archaeological situations. The aim of this analysis is to determine a range of cultural plants and also to reconstruct past agrotechnical practices and processes and agricultural...
