The aim of the work is to present the interdisciplinary projects developed and funded by the Bulgarian Science Research Found. These projects are created in Departments of Archaeology, and Natural Sciences, New Bulgarian University in the period 2014–2019.
Using X-ray fluorescence and Powder X-ray diffraction analysis, the chemical and phase composition of ancient iron slags and raw iron ore were investigated. The type of raw ore was identified as self-fluxing. The operating furnace temperature was determined in the range 900–1000 °C. The results obtained are of archaeological importance. They will contribute to the chronological specification of the time of realization of the metallurgical process and the type of used furnaces.
The main objective of this paper is to present the fieldwork results ofarchaeological and geological investigations in the area of Hadjiyska river and the southern slopesof Eminska Stara Planina in Bulgaria. The area of interest is home to a large number ofarcheological findings dating back from the Late Antiquity (4-6th c.) and the Middle Ages (7-18thc.), and fewer from older periods (prehistorical, Thracian and Roman periods). Geologicalobservations show presence of alluvial, prolluvial-delluvial, and prolluvial hollocen sediments.Combining the results of archaeological and geological research allowed for (i) the verification ofthe hypothesis that older archaeological objects are covered by accumulated sediments, and (ii) anattempt to look into the livelihood in the area.
Geo-archaeological field surveys have been carried out in the Western part of the Zlatitsa-Pirdop valley. Archaeological sites and surface collections, traces of metalworking of iron were registered to restore the economic models in ancient times.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
