It will serve as a basis for research on a new type of facility for Combined Heat, Power and Metal extraction (CHPM). The five reports, written by individual working groups from the United Kingdom (UK), Portugal, Romania, Sweden and the European Federation of Geologists (EFG) are attached here in original form as appendices 1.2.1 to 1.2.5. They mainly comprise geological, geophysical and geochemical data on and descriptions of mineralized areas in these countries. The EFG report presents a European inventory of drill holes with temperatures in excess of 100°C, availability of data for these holes, and any metal enrichments having been encountered at depth. The target areas in the specified countries belong to three large metallogenic provinces in Europe: the Precambrian Fennoscandian Shield province, as for Sweden; the late Paleozoic Variscan province, as for SW England and southern Portugal; and the Mesozoic-Cenozoic Alpine province, as for NW Romania. In these provinces prospective zones suitable for the CHPM technology should be evaluated. Much is already known about the geology, mineralisation, fluids and the geothermal potential of the ore districts, discussed in this report. However, the knowledge often is restricted to the upper 1 000 m of the crust or less. Locally, where deep drilling has been performed, the conditions may be evaluated to greater depths. The availability of data has significant implications regarding the accuracy of modelled conditions in an enhanced geothermal system (EGS) at greater depths. Therefore, the structural information and the knowledge of the physical state of the upper crust need to be enlarged considerably in order to meet the goals of the CHPM project. 4/18 CHPM2030 DELIVERABLE 1.2 0 Preface This report describes what is already known about the geology, mineralisation, fluids and the geothermal potential of the areas of interest. It is one of the first deliverables of the CHPM2030 project - an EC-funded Horizon2020 project which aims to develop a novel and potentially disruptive technology that can help satisfy European needs for energy and critical metals in a single interlinked process. Working at the frontiers of geothermal resources development, minerals extraction and electro-metallurgy, the project aims to convert ultra-deep metallic mineralisations into orebody- enhanced geothermal systems (EGS). It will serve as a basis for the development of a new type of facility for Combined Heat, Power and Metal extraction (CHPM). The project will help providing new impetus to geothermal development in Europe by investigating previously unexplored pathways at low-TRL. This will be achieved by developing a roadmap in support of the pilot implementation of such system before 2025, and the full-scale commercial implementation before 2030. It will include detailed specifications of this new type of future EGS facility (CHPM). In the technology envisioned, the metal-bearing geological formation will be manipulated in a way that the co-production of thermal energy and metals

    Geological Quarterly, 2006, 50 (1): 23–32 Lithospheric structure of the TESZ in Poland based on modern seismic experiments Aleksander GUTERCH and Marek GRAD Guterch A. and Grad M. (2006) — Lithospheric structure of the TESZ in Poland based on modern seismic experiments. Geol. Quart., 50 (1): 23–32. Warszawa. This paper presents the results of seismic investigations on the structure of the lithosphere in the area of the Trans-European Suture Zone (TESZ) in Poland that is located between the southwestern margin of the East European Craton (EEC) to the north-east, the West and Central European Palaeozoic Platform (PP) to the south-west and the Carpathians to the south. Based on results of the modern POLONAISE’97 and CELEBRATION 2000 projects, as well as older profiles, models are presented for the configuration and extent of different crustal types. In the investigated area, the EEC has a relatively uniform crustal thickness of 40 to 50 km with its three-layered crystalline crust displaying P-wave velocities of 6.1–6.4, 6.5–6.8 and 6.9–7.2 km/s in the upper, middle and lower parts, respectively. The Variscan consolidated crust is covered by 1–2 km thick sediments and consists of two layers with velocities of 5.6–6.3 and 6.5–6.65 km/s. In the Carpathians, sediments reaching to depths of some 20 km and are characterized by velocities of <5.6–5.8 km/s, whilst the underlying two-layered crystalline crust displays velocities of 6.0–6.2 and 6.5–6.9 km/s.

Geologische Reichsanstalt (Vienna, Austria) in Slovakia during the period 1850-1869 OTO MIKO*) Abstract As early as two decades after the establishment of the k.k. Geologische Reichsanstalt in Vienna the entire Austro Hungarian Empire was researched and the overview geologic map at 1:576 000 scale was published. The research was based on stratigraphic data supported by paleontologic findings, on study of rock-forming minerals, on investigation of mineral deposits, on topographic surveys and other methods. Those who made the best contributions to the knowledge of the geology of Slovakia during this early period of research were D. STUR, F. FOETTERLE, F. ANDRIAN, CM. PAUL, G. STÄCHE, F. HAUER, M.V. LIPOLD and H. WOLF. They and many other members of the "Vienna geolo­ gical school" laid the foundations of the modern Carpathian geology.

O. Box 106, 840 05 Bratislava, Slovak Republic; e-mail: [email protected] Abstract: The main aim of this study is to compile 2-D density model of the CELEBRA- TION 2000 profile CEL12, which is based on seismic refraction data. The profile CEL12 crosses the External Western Carpathians Flysch zone and is located in the southern part of Poland. The general feature of the resultant density model shows significant changes in the crustal thickness. The Moho depth changes in the interval from 31 km to 43 km. The interpreted 43 km crustal thickness over a 60 km section of the profile results in the discovery of an area, which represents the thickest crust in the entire West Carpathians. This area is situated ∼50 km north-east from the High Tatras in Poland.

The metacarbonates are characterized by high LOI and CaO and by small contents of various insoluble components. Among the trace elements investigated, only As, Ba, Co, Cu, Hg, Nb, Ni, Pb, Rb, Sb, Sr, Th, U, Y, Zn, and Zr display concentrations beyond their detection limits. The metacarbonates are strongly depleted in Rb, Ba, Th, Nb, Hf, Zr, and Y and enriched in U and Sr relative to the UCC. Chondrite-normalized rare earth element patterns of the metacarbonates show a moderate to strong fractionation in light rare earth elements over heavy rare earth elements and distinct negative Ce and Eu anomalies. Variation plots reveal several geochemical interrelationships, among which SiO2 – Al2O3 – K2O – TiO2 – Ba – Nb – Rb – Zr are associated with the rock’s silicate fraction.

    Joint analysis of the magnetic field and Total Gradient Intensity in Central Europe Maurizio Milano 1, Maurizio Fedi 2, J. Derek Fairhead 3 5 1 Centro Interdipartimentale di Ricerca L.U.P.T. – Università degli Studi di Napoli Federico II. 2 Dipartimento di Scienze della Terra, dell’Ambiente e delle Risorse - Università degli Studi di Napoli Federico II. 3 School of Earth and Environment, University of Leeds, UK. Correspondence to: Maurizio Milano ([email protected]) 10 Abstract. In the European region, the magnetic field at satellite altitudes (~350 km) is mainly defined by a long-wavelength magnetic-low called here the Central Europe Magnetic Low (CEML), located to the southwest of the Trans European Suture Zone (TESZ). We studied this area by a joint analysis of the magnetic and total gradient (∇T) anomaly maps, for a range of different altitudes 15 of 5 km, 100 km and 350 km. Tests on synthetic models showed the usefulness of the joint analysis at various altitudes to identify reverse dipolar anomalies and to characterize areas in which magnetization is weak. By this way we identified areas where either reversely or normally magnetized sources are locally dominant. At a European scale these anomalies are sparse, with a low degree of coalescence effect. The ∇T map indeed presents generally small values within the CEML area, indicating that the Palaeozoic Platform is weakly magnetized. 20 At 350 km altitude, the TESZ effect is largely dominant: with intense ∇T highs above the East European Craton (EEC) and very small values above the Palaeozoic Platform, this again denoting a weakly magnetized crust.
