“…The models of solid solutions from [Avchenko et al, 2009] were used to describe Ca-clinopyroxene, Na-amphibole, Ca-amphibole, and titanomagnetite. Olivine and serpentine were also described by solid solutions models [Shestopalov et al, 2022] as well as illite and smectite [Koliabina et al, 2009]. Other solid solutions models were already included in the GEMS database.…”

“…However, these processes are of relatively slow diffuse nature. We studied another case, in which hydrogen is not a product of rock-water interaction, but serves as an initiator of the rock modification process under the action of the ascending gas fluid with its high concentration [Shestopalov et al, 2022].…”

“…This constitutes only one fifth of the hydrocarbon potential of the basin [Lukin et al, 2020]. This potential was formed in the relatively recent geological history due to a giant hydrogen blowing of carbon-containing mantle rocks [Shestopalov et al, 2018[Shestopalov et al, , 2022. Apparently, such blowing occurred repeatedly during the rift history and was of a periodic, pulsating nature.…”

“…Well sampling shows that these deposits contain admixtures of unspent hydrogen. Besides, the hydrogen also forms independent seeps to a shallow depth [Lukin, Shestopalov, 2021;Shestopalov et al, 2022]. The data available [Lepigov et al, 2011] indicate that degassing and fluid recharge pulses have occurred many times and are still occurring.…”

This work considers the possibility of native aluminum transport with hydrogen fluid, its deposition and preservation in sedimentary rocks, as well as an assessment of the conditions under which this is possible. This problem is currently debatable and is considered in a number of publications. Native aluminum was found in different types of sedimentary rocks of oil-and-gas-bearing basins. So the presence of native aluminum spherulas was established in the dolomites of the Dnipro-Donetsk Basin. By the example of these findings this work shows that the necessary conditions for the formation and long-term preservation of native aluminum are: its migration with the hydrogen flow into the upper layers of the Earth’s crust, the creation of temperature and pressure conditions causing water to vaporize, and the formation of a protective film on the surface of the formed native aluminum. The process of native aluminum formation in the sedimentary rocks of oil-and-gas-bearing deposits of the Dnipro-Donetsk Rift described in this work, as well as its findings in other basins indicates the typical character of this process for rift structures of hydrocarbon accumulation. It was assumed, that the oil-and-gas-bearing structure of Dnipro-Donetsk Rift is mantle origin and represents a giant source of deep hydrogen. Some of this hydrogen is consumed to form hydrocarbon accumulations, including known oil and gas deposits, and some of it degasses into the uppermost layers of the Earth’s crust. Independent hydrogen fields can also form there, as was the case during the formation of the deposit of geological hydrogen in Mali. It was shown, that the presence of hydrocarbons in the fluids does not affect the processes associated with aluminum. The results obtained indicate significant flows of hydrogen from the mantle to the upper horizons of the Earth’s crust. Thus, native aluminum, as well as other native oxyphilic metals in sedimentary rocks of oil-and-gas bearing basins is a search marker of both hydrocarbon accumulations and the important role of deep geological hydrogen in the formation of these accumulations and its possible accumulation in the most reliable traps.

The scope of this work is to empirically check and prove the practical applicability of the Primordially Hydridic Earth (PHE) concept for early exploration of the resources of naturally occurring hydrogen. With the PHE concept postulates interpreted within the local geological, tectonic, petrological and geophysical context, the reconnaissance plan, as well as the field exploration and data acquisition programs, were put together and implemented in the field. The results obtained from the surface (<1m deep) soil gas survey performed in Western Australia (WA) resulted in values of hundreds of ppm H2, including three samples with a concentration of hydrogen exceeding the gas sensor detection limit of 2,000 parts per million (ppm) (the all-Australia record). Similarly, several of the shallow soil samples used for obtaining headspace gas extracts yielded dozens % H2, which was established utilizing Gas Chromatography (GC) technology. The latter tests established the all-Australia record of 58.3% (norm.) H2 concentration from 15 m depth, being the highest reading from the area of research. At one location, a concentration of He exceeding 8,000ppm was detected in a 1m surface soil gas sample analyzed by the independent lab. The most important outcome was finding natural hydrogen where it was expected and predicted. On the other hand, H2 concentrations exceeding the natural background of 1-3ppm were not detected in the soil gas readings outside of the areas identified using the PHE concept as a theoretical foundation. It may be stated that overall, the practical application of the PHE concept along with the thoroughly planned utilization of carefully selected exploration techniques brings satisfactory results.

This paper shows the prospect to find industrial-scale hydrogen accumulations in riftogenic structures of platforms using the example of the Dnieper-Donets Aulacogene, located in the southern part of the East European Platform. Within the Dnieper-Donets Depression, geological and geophysical methods indicate a significant number of deep faults and ring structures of volcanogenic and explosive origin promising increased hydrogen content. Possible locations of the most propitious areas of hydrogen concentration are associated with faults in rift systems and their nearest margins, as well as with explosive and volcanogenic ring structures with signs of modern activation. At a fine-grained level, the prospectivity of the area is determined not only by the specified structural relationship, but also by the set of geophysical characteristics (thermal, seismic, gravity, electrical conductivity, magnetic) and the corresponding geological and hydrogeological parameters. Areas for further more detailed investigations within the Sribne and other ring structures, Southern Near-Edge Fault, Northern Near-Edge Fault were identified based on the data on geological and geophysical materials, satellite images, and field work. We defined high-priority and low-priority territories. Areas for initial investigations using satellite images, gas sampling (hydrogen, helium, methane, etc.), primary geophysical surveys (with evaluation of intermediate reservoirs and cap rocks) were identified. The primary results can be used to plan pilot shallow drilling and wells sampling. The areas for priority deeper drilling and sampling are selected by the sum of results obtained and data comparison. The paper presents the results obtained 30 km east of Kyiv as an example of field assessment of H2 degassing in a local depression. The results show that hydrogen concentrations at depths of 0.45 to 1.5 m are near zero outside the local depression. The maximum values of H2 concentration (up to 3300 ppm 1.5 m deep) are characteristic of the point inside the depression.
