20^th March 2020., Zagreb (Croatia)

As a result of an extensive field survey of wider area of Kalinovac – Hrastova greda site, bog iron ore fragments were found. They originate from a layer of ore/ore lens formed as a subsurface layer beneath topsoil. According to preliminary macroscopic analysis these samples represent the third formation stage of the bog iron ores. During several field campaigns on the Kalinovac – Hrastova greda site, samples of soil, nodules or concretions and fragments originating from bog iron ore subsurface layer/lens were collected. These represent three main stages of the bog iron ore formation process in the Podravina region.

autumn/winter 2018

During late autumn and winter of 2018, the workers of the Koprivnica Museum (R. Čimin, I. Valent) and Ivan Zvijerac from Torčec conducted field survey and reambulation of the terrain around Novigrad Podravski, Koprivnički Bregi and Molve in order to find new sites with smelting infrastructure for scientific purposes of the research project TransFER (pdf)

16^th November 2017

On 16^th of November a field survey of nine potential archaeological sites was conducted in the vicinity of Vlaislava, Plavšinac, Srdinac and Delovi, selected from aerial photographs (T. Tkalčec, S. Krznar, I. Valent, T. Sekelj Ivančan). Surface finds from Prehistory to Modern Age in the selected locations have been found (pdf).

9^th and 10^th November 2017

During 9^th and 10^th of November 2017, Institute's researchers (T. Sekelj Ivančan, S. Krznar) conducted field survey of five sites in Drava region with indicative toponyms associated with metallurgical activity and/or processing of metal (iron) with the aim of collecting possible surface residues and their determination. Field surveys were carried out together with a collaborator on the project from Koprivnica Town Museum (I. Valent) and the guidance of J. Cugovčan. Several positions were found with settlement surface finds from Prehistory, Middle Ages and Modern Age, while a single site was found containing fragments of smelting slag (pdf).

2^nd of March – 15^th May 2017

From March 2^nd to May 15^th 2017, Institute's researchers (T. Sekelj Ivančan, S. Krznar) will be carrying out field surveys and reambulation within the Podravina region, from the confluence of Mura and Drava Rivers to Podravske Sesvete and Pitomača. Filed surveys are carried out in cooperation with project's collaborators (R. Čimin, I. Valent) within the framework of the research project TransFER, financed by the Croatian Science Foundation (pdf).
