Geological prospection of partly accessible constructional pit for the hydroelectric power plant (HPP) Brežice was performed. Paleontological content and sediment-petrographic characteristics of rocks were investigated. Neogene part of the succession consists of carbonate silt and siltstone with intercalations of carbonate and silicate sandstone, and polymict sandstone to conglomerate. Based on foraminifera, ostracods, molluscs and marine mammals, the Upper Badenian and Lower Sarmatian age of beds and boundary between them have been determined. The transition is characterized by a shorter break in sedimentation and environmental change. Fossil finds indicate that salinity and depth of sedimentary basin were oscilating in Sarmatian, but in general decreasing. Quaternary cover beds consist of gravelly, sandy and silty deposits of the Sava River. © Author(s) 2016.

The GeoERA proposal is put forward by the national and regional Geological Survey Organisations (GSO) of Europe. Its overall goal is to integrate the GSOs information and knowledge on subsurface energy, water and raw material resources, to support sustainable use of the subsurface in addressing Europes grand challenges. The GeoERA consortium will organise and co-fund together with the EC a joint call for transnational research projects that address the development of 1) interoperable, pan-European data and information services on the distribution of geo-energy, groundwater and raw material resources; 2) common assessment frameworks and methodologies supporting better understanding and management of the water-energy-raw materials nexus and potential impacts and risks of subsurface use; 3) knowledge and services aimed at European, national and regional policy makers, industry and other stakeholders to support a more integrated and efficient management and more responsible and publicly accepted exploitation and use of the subsurface. The transnational projects selected in the call will be implemented by the consortium partners themselves, who provide their co-funding in-kind. GeoERA will contribute to the overall EU objective of building the ERA through enhanced cooperation and coordination of national and regional Geological Survey research programmes. GeoERA will also include forward looking activities, including the creation of opportunities for future collaborative research, and the feasibility assessment of an Article 185 initiative in Applied Geoscience as follow-up to the GeoERA ERA-NET towards the development of the ultimate goal of delivering a Geological Service for Europe.

The Minerals4EU project is designed to meet the recommendations of the Raw Materials Initiative and will develop an EU Mineral intelligence network structure delivering a web portal, a European Minerals Yearbook and foresight studies. The network will provide data, information and knowledge on mineral resources around Europe, based on an accepted business model, making a fundamental contribution to the European Innovation Partnership on Raw Materials (EIP RM), seen by the Competitiveness Council as key for the successful implementation of the major EU2020 policies.The Minerals4EU project will firstly establish the EU minerals intelligence network structure, comprising European minerals data providers and stakeholders, and transform this into a sustainable operational service. Minerals4EU will therefore contribute to and support decision making on the policy and adaptation strategies of the Commission, as well as supporting the security of EU resource and raw materials supply, by developing a network structure with mineral information data and products, based on authoritative of information sources.The Minerals4EU project is built around an INSPIRE compatible infrastructure that enables EU geological surveys and other partners to share mineral information and knowledge, and stakeholders to find, view and acquire standardized and harmonized georesource and related data. The target of the Minerals4EU project is to integrate the best available mineral expertise and information based on the knowledge base of member geological surveys and other relevant stakeholders, in support of public policy-making, industry, society, communication and education purposes at European and international levels. The Minerals4EU consortium possesses the skills and resources to make this the leading European mineral information network structure that will provide tools and expertise to enhance resource efficiency, minerals supply security and support sustainable mineral development for Europe.

Geological and engineering-geological properties of flysch in the region of Kaštela are presented. Exogenetic processes characterizing the area under study are defined and described. Flysch formations are classified according to morphological and sedimentological criteria, which has enabled a separate study of their engineering-geological properties. A particular attention is paid to the definition of engineering-geological properties of lithological units identified in the flysch and, in this context, typical GSI values are allocated to such units.\.

Shifts of structural units, which started in Pliocene are specifically expressed during the Quaternary. They last still today and affected the hydrogeological relations in the region of Baranja. Lithological development is dominated by one or maximum two layers of uniform midium grained sand which in places exceeds to fine grained sand, and in some places in the sand with gravel. Mentioned structures have impacted the natural quality of groundwater. Considering individual episodes of uplift and lowering of sediments, caused by movements along a particular structures, led to changes in oxidative and reductive conditions of deposition. Consequently, different quality of water occurs in wellfields of Baranja.

The most significant methods for estimating the uniaxial compressive strength and Young's modulus of intact rock material, formulated in the scope of numerous previous studies, are briefly presented in the paper. The proposal for classification of these methods, according to which they can generally be divided into simple and complex methods, is also presented. Simple methods include various diagrams and tables and the use of simple regression equations, while complex methods comprise the use of multiple regression equations, fuzzy logic models, neural networks, evolutionary programming, and regression trees.

Geochemical atlas of Croatia resulted from the regional geochemical survey based on the low-density (1 sample per 25km 2) soil sampling having covered the entire territory of the state. Basically, the collection of maps showing distribution of a set of elements with particular emphasis of possibly harmful elements (PHE) was focused on elucidation of environmental implications brought about by human impact (ingress of Pb, Zn, Cd and other elements derived from anthropogenic sources) against some zero-level represented by geochemical background. However, the effect of blending of anthropogenic and natural (geogene) signal in the upper soil was already recognized during the mapping campaign having steered further research to assessment of geological imprint in the soil geochemical signature. Therefore this work was also aimed at finding appropriate avenues to understanding how both signals behave at various scales (regional or local). Using suitable statistical techniques (posterior probabilities from discriminant function analysis (DFA)) it was found that anthropogenic signal may be completely obliterated by the geogenic geochemical signature at a larger, regional, scale, which is otherwise locally strong and adversely affects the environment (e.g. PHE with regard to the Drava River). © 2012 Elsevier B.V.
