“…Zgonnik (2020) reported the presence of H 2 in some iron ore mines exploiting banded iron formation in the Kryvyi Rih region (Ukraine). Berezovsky et al (2021) recently described gold mineralization together with hydrothermal carbonates at the same locality. Gold mineralization in banded iron formations were also described in the Olenegorsk belt of the Kola Province Kalinin et al (2019).…”

“…At the Trypillia stage CII (3500-3000 BC), the metallurgical knowledge spread further to the east and reached the banks of the river Dnipro. Here, the metallurgical raw material is represented by the deposits of chalcopyrite in the areas of Verkhivtseve, Kruta Balka, Surs'ske, Kremenchuk (Grinchenko et al 2006, 91) and Kryvyi Rih (Berezovsky et al 2021). The most common metal artefact originating from the Dnipro basin is the copper jewellery found within the kurgan burials of the Serezlievka local group of the Late Trypillia culture.…”

According to the classical model of the metallurgical raw material supply chain proposed by Eugeniy Chernykh, the Eneolithic and Early Bronze age cultures of Ukraine were completely dependent on imported raw material. It seems that the main supplier of metal, as well as some complete goods during the 5th and 4th Millennia BC, was the ‘Carpatho-Balkan Metallurgical Province (CBMP)’ while during the 3rd Millennium BC, the provision chain was reoriented towards the ‘Circumpontic Metallurgical Province (CMP)’. Yet, new discoveries that were made during the 1990s-2020s indicate the need for the amendment of such a model. This is the aim of the current paper. In the following text, the concept of four Ukrainian local metallurgical provinces and two metalworking foci will be introduced. The typology and dating of the recently discovered metal objects as well as metallurgical tools will be provided. The question of the existence of domestic metallurgical raw material deposits will be discussed.

A review of the localities in continental rocks where H2-rich gases have been reported, showed that they are mainly located near gold deposits. Two types of geomorphological features known as markers of gas venting in sedimentary basins were also systematically observed near orogenic gold deposits on satellite images. They consist in both barren ground depressions and high densities of small (< 20 m in diameter) circular- and comet-shaped white spots in 32 and 7 localities, respectively. Point pattern analysis revealed that the white spots are self-organized, and similar to previously described vegetation patterns including termite mounds and fairy circles. We proposed a geochemical model to account for this relationship between orogenic gold deposits, H2 emanations and geomorphological features. Fe-carbonates are ubiquitous mineral products associated with gold mineralization. They can further dissolve in the presence of aqueous fluid due to their high reactivity below 200°C to produce magnetite and up to ~ 1 mole of H2 per kg of rock along with ~ 3 mol/kg CO2. This process induces a solid volume decrease of 50 %. Therefore, we propose that Fe-carbonate dissolution is (1) the primary source of H2 in orogenic gold deposit areas, and (2) involved in the formation of the geomorphological structures reported here, providing a new framework to understand their seemingly complex formation. Ground depressions and white spots are possible tools for gold explorations. Actually, we identified four new areas where we suspect possible orogenic gold deposits. The association between H2-rich gas and ground depressions was also made near other formations containing Fe-carbonates such as iron formations and carbonatites. This suggests that H2 production through Fe-carbonate dissolution is not restricted to gold deposits. The global H2 production in crustal rocks associated with Fe-carbonate alteration is estimated to 3.10^5 mol/yr.
