A feltételezett kráter vizsgálatát a korábbi közlés óta kiterjesztettük a területen elérhető minden geofizikai adatra. Az újabb vizsgálatok részben megerősítették az úgynevezett „dabronyi szerkezet” becsapódási eredetét, másrészt viszont további kérdéseket vetettek fel. Jelen munkánkban ezekről a vizsgálatokról számolunk be. Regarding that gravity anomalies of Dabrony area (NW Hungary) showing considerable similarity to those of proven impact craters, a large buried impact structure (d ~ 20–25 km) has been assumed here. In the years past all available geophysical data of the area have been studied. On the one hand, the results fit well into the impact hypothesis, on the other hand, they raise further questions. The paper gives an account of the present state of the issue.

Data supply to the Hungarian State Mineral Raw Material and Geothermic Energy Resources Registry is based on the obligatory yearly data supply of mining contractors; MBFSZ produces yearly datasets from them. Information contained in the hydrocarbon register contains information on units referred to hydrocarbon reservoir levels field by field. This registry contains data related to already discovered, explored hydrocarbon accumulations. The register database contains data of hydrocarbon quantities for each and every reservoir as follows: resource initially in place, initially recoverable resource, summarised production, production of the actual year, and the recoverable resource as of January 1. These data and information sets are separately given for conventional crude oil, free natural gas, gas cap gas, dissolved gas, CO2 gas and for unconventional gas and condensate resource quantities. Besides resources data, the registry contains basic parameters for crude oil and natural gas, such as their composition, along with fundamental parameters of the reservoir such as the depth of oil-water, gas-water, gas-oil contact boundary compared to relative sea level, porosity, permeability, gas- and oil saturation, besides other information required for mineral resource estimation. Also provides data about the quality of reservoir rock, the mineral composition and physical parameters of its reserved fluid content. The register contains a number of geological data on the reservoirs and fields that provide valuable information on the quantitative changes in the domestic hydrocarbon resources, the quality composition of the stored fluids, and the physical properties of the reservoir rocks. Based on the statistical processing of the data, estimates can be made for the amount of oil and natural gas can be discovered in the future, and the analysis of hydrocarbon geological data helps to understand the Hungarian petroleum systems and to plan future exploration.

AB - The rare-earth bentonites were prepared from Ca-bentonite by suspending Ca-bentonite in rare-earth (Ce, La, Y) perchlorate solution. 57Fe Mössbauer spectra of rare earth montmorillonites before heat treatments showed a doublet envelop at room temperature, reflecting dominantly Fe3+ assigned to (cis) octahedral site in the montmorillonite. At the same time, the 80 K spectra of these rare-earth exchanged montmorillonites revealed an additional magnetically split component, too, associated with iron atoms intercalated in the interlayer space. In the case of heat treated samples (250 °C, 360 °C and 500 °C for 4 h), a new doublet component associated with Fe3+ at trans octahedral site, appeared in both the 295 K and 80 K Mössbauer spectra. Powder X-ray diffractometry (XRD) measurements of the heat treated rare earth montmorillonites revealed that a gradual mineral phase transformation of montmorillonite to muscovite occurred upon the applied heat treatments, being consistent with the completing electron magnetic resonance (EMR) and Mössbauer spectroscopy (MS) results.

PY - 2018 SP - 405 EP - 405 PG - 1 UR - https://m2.mtmt.hu/api/publication/31286124 ID - 31286124 AB - A natural CO2 reservoir system with a sandstone lithology in NW Hungary has been studied due to its similarities to a large saline reservoir formation that is widespread in the the Pannonian Basin (Central Europe) and is suggested to be one of the best candidates for industrial CO2 storage. A range of analytical techniques has been used on core samples from CO2-containing sandstone layers that represent a wide range of pressures (90–155 bar), temperatures (79–958C) and pore fluid compositions (total dissolved solids between 18 000 and 50 700 mg l21) to identify the mineralogy and textural characteristics of the natural reservoir. The only clear CO2-related feature in the studied lithology was the occurrence of dawsonite (NaAlCO3(OH)2) in a close textural relationship with albite. This is in clear agreement with our geochemical modelling results, which also underline the presence of albite as a precondition for the crystallization of dawsonite at the given P–T–X conditions. Our results suggest that, at least in the Pannonian Basin, dawsonite may be an important mineral for the safe sequestration of industrial CO2 in the subsurface. LA - English DB - MTMT ER -
