They can be found unchanged or slightly changed (eg. in the form of jewellery, simple tools, pigments). On the other hand, they can be significantly altered forming man-made materials (eg. glass, ceramics). The main goals of this presentation are: (1) to classify different geological materials such as minerals, rocks, soils, sediments and ores, and present their usage in ancient times ; (2) to describe their occurrences and availability in the nature with emphasis on the area of today’s Croatia and south-eastern Europe ; (3) to describe their characteristics which made them raw materials, as well as their changes during technological processes ; and (4) to describe tools for provenance determinations. Purpose of the presentation is to acquaint archaeological audience with the possibilities and problems of provenance analysis.

Slope instability in flysch rock formations along the northern Adriatic coast of Croatia is related to the effects of weathering on the shear strength of siltstones from the flysch rock mass. Therefore, changes in geotechnical properties according to weathering grade are of immense importance in relation to instability processes. In this work, we investigated siltstones from flysch rock masses in the study area, and evaluated changes in engineering properties due to weathering. The research began with field observations and determination of the strength of different weathering grades of siltstones in the area. Mineralogical and laboratory studies were subsequently conducted, and mineral content was determined for siltstones of different weathering grades. We also performed a series of drying–wetting cycles to simulate natural conditions of the weathering process involved in the disintegration of the rock material into sand-sized and smaller particles. This weathering process resulted in disintegration of the siltstone rock mass into smaller particles that were not a unique rock block, with the soil-like material consisting of unbound particles of rock. Laboratory tests were also carried out on the soil-like material to determine the specific gravity, grain size distribution, Atterberg limits and residual shear strength for the different weathering grades of siltstones. Based on this research, we determined the changes in engineering properties for different weathering grades. Our results underscore the significant influence of the weathering process on mineral content, cation exchange capacity, liquid limit and residual shear strength, thus affecting slope stability in siltstones in flysch rock masses.

Here, the main strengths and challenges of the mineral sector of the Adria region were assessed using the following methodology: (1) presentation of the current status of mineral exploration and exploitation, (2) SWOT (Strengths, Weaknesses, Opportunities, Threats) analysis on parameters including geological potential, economic environment, legal and regulatory framework, innovation and technology framework, environmental protection and land use planning, governmental and social potential, human resources and educational potential, (3) Gap analysis, and (4) integration of the results obtained in the development of a roadmap for the actions required to promote investments in the mineral sector in the Adria region. The main strengths of the regional mineral sector include the significant mineral potential due to a favourable geological setting, significant reserves, a long mining tradition, and active exploration areas, as well as a significant number of active and abundant mines and the availability of secondary raw materials. Nevertheless, there are many challenges that the mineral sector faces, such as difficulties in ensuring social acceptance, a lack of new exploration campaigns in many areas, estimation of resources or reserves that do not follow international codes and standards, regulations related to environmental issues in the mineral sector of Adria countries that do not comply with European legislation, and the limited availability of qualified technical, scientific and managerial personnel involved in the whole mineral cycle. Therefore, actions and measures such as awareness campaigns to highlight the significance of Raw Materials in the sustainable development of the region, further exploration, reserves calculation in alignment with internationally recognized codes, harmonization with spatial plans, and reforms to attract investors and capacity building programs should be taken for further development of the Adria region's mineral sector in a sustainable manner.

The subject of this biannual research project is ceramic material from different prehistoric cultures that existed in the south-east Alpine region and part of the Croatian Danube region. Ceramics, as other handmade artefacts, reveal a social context of man in the past – his behaviour and activities as well as the social, economic and political arrangement. The main goals of the project are: (1) to determine the availability, as well as mineral and chemical characteristics, of raw materials ; and (2) to reconstruct technological processes (selection raw material, preparation of clay paste, modelling techniques ; firing methods, styles of decoration) of pottery production. Some of the major centres, in terms of prehistoric settlements and cultures, were situated along the Danube and its tributaries. Danube was one of the most important trade links on the European continent. The purpose of the project is to determine to what extent Danube can be seen as a unique area in prehistoric times, by examining: (1) whether the exchange of material goods included the exchange of technology (at the level of cultural horizon or at the level of smaller communities), or it is always related to the production centre, and (2) to which extent technological processes were conditioned by landscape (availability of raw materials), economic or social factors (matter of choice). In the frame of the project, analysed material includes artefacts from Early Neolithic to the Roman period, as well as possible raw materials, from five archaeological sites of the Austrian and Croatian Danube region. The most famous site is Hallstat, represented by late Bronze and early Iron Age culture. It is the type site of the Hallstatt culture, the predominant Central European culture from the 8th to 6th centuries BC (European Early Iron Age), developing out of the Urnfield culture of the 12th century BC (Late Bronze Age) and followed in much of Central Europe by the La Tene culture. Two other important sites are tell Damica gradina in Stari Mikanovci and tell Tržnica in the centre of Vinkovci. A tell is a hill created by many generations of people living and rebuilding on the same spot. Over time, the level rises, forming a mound. This multi-layered tell sites represent a very good examples of continuity of settling from the Early Neolithic period. Tell Damica gradina was inhabited continuously during 6000 years and Vinkovci, as they are settled even today, represents one of the oldest continuously inhabited places in Europe with about 8500 years of continuous settlement. The last two sites, situated in northwestern Croatia (Kurilovec-Belinscica in Turopolje and Selnica Podvratnec, Podgorica and Mocvar in Podravina), belong to the broader cultural horizon of the Urnfield culture. In order to achieve the appointed objectives, interdisciplinary approach and the cooperation of scientists from two completely different areas, natural sciences (geology) and the humanities (archaeology) is necessary. Archaeological part of the team has been responsible for collecting ceramic material, describing the context, making experimental ceramics and resolving archaeological problems, based on the results of the geological team. Part of the team whose specialty is geology has been responsible for reconnaissance of the availability of raw materials in the vicinity of investigated sites, as well as interpretation of chemical and mineralogical data order to determine the provenance of raw material and the technology. Archaeometric analysis of pottery fragments was essential step in the reconstruction of the technological process and their results indicate provenance of raw materials, a recipe for the clay mixture and the firing regime.

Formation of badlands, creeping and sliding processes have been related to crystallization of thenardite. Unusually intense erosion is caused by the dispersive effect of sodium on clay particles (derived from pelitic fl ysch intervals) in solution, as well as by expansion of thenardite during transformation into a deckahydrate (with a four fold increase in volume). The search for a sodium source required for thenardite crystallization has focused on a particular composition of Slani Potok Eocene fl ysch rock types. Slani Potok fl ysch is predominantly composed of pelitic intervals, with subordinate sandstones and biocalcirudites. Sandstones and biocalcirudites contain appreciable amounts of siliciclastic detritus. Lithic fragments are represented by volcanic rocks revealing porphyry structures-possibly andesite or altered volcanic glass fragments, quartzite, schists, shales, and carbonate grains. High amounts of sodium and barium (0.93-1.09 % and 267-276 mg/kg respectively), in marls and sandstones, is essentially ascribed to a particular composition of fl ysch, refl ecting its area of provenance. A Palaeozoic clastic complex with barite mineralization, (black shales, sandstones and conglomerates), as well as a Mesozoic hornblende andesite located near Fužinski Benkovac in the Gorski Kotar region, are interpreted as fl ysch source rocks. Sodium at least could be partly leached from the lithic and feldspar grains in clastic rocks, due to circulation of pore fl uids. An increased amount of sulphur, barium and strontium in fl ysch can be related to that of a barite ore complex in the source area of the Gorski Kotar region. Transportation and deposition of material eroded from the hinterland (North of Slani Potok), suggests turbidity current fl ow was transverse to the main axis of the Eocene foreland basin striking NW-SE.

Even at that time climate change was a fact: Due to global warming water evaporated and huge amounts of salt crystallized. 7000 years ago people discovered these salt deposits, settled in Hallstatt and started salt mining. Pottery was used in everyday life and also as grave goods. During the last 200 years archeologists excavated various ceramic products and many potsherds from Bronze Age, Iron Age and Roman times. For this study about 30 different shards and samples from some clay pits in the surrounding of Hallstatt were selected and analyzed. Bulk and clay mineral composition of shards and potential raw materials were determined by X-Ray Diffraction (XRD) and Simultaneous Thermal Analysis (STA). Cation exchange capacity of all samples and grain size distribution and consistency limits of the raw materials were measured. Trace elements were analyzed by ICP-MS to obtain information about the provenance of...

The operationally defined phases selected for extraction have been assigned to the following five fractions: adsorbed, bound to carbonates, bound to Fe-Mn oxides, bound to organic matter and residual. The following reagents had been used: NH4-aceate, Na-acetate, hydroxylamine hydrochloride, hydrogen peroxide + nitric acid, mixed acids (HCI-HNO3-HF), respectively. The solutions were analysed by atomic absorption flame photometry (Pb and Cd) and inductively coupled plasma atomic absorption photometry (other analysed elements). Mineralogical analysis was performed to detect Zn-Pb-bearing phases and cerussite was the only phase detected. Other mineral phases detected by XRD in the soil samples were as follows: quartz, dolomite, micas, plagioclase, K-feldspar, goethite, hydrargillite, kaolinite, chlorite, and organic matter. Assuming that mobility and biological availability are related to the solubility of the geochemical forms of the metals and the latter decreases in the order of extraction, the apparent mobility and potential metal bio-availability for these highly contaminated soils is: Cd> Pb> Zn> Cu> Ni. The distribution of Pb, Zn and Mn in mineral phases is similar in samples with both high and baseline trace-metal values. Cu, Fe, and Ni exhibit different distribution patterns in the two types of samples.
