For principle reducing emissions of CO2, now and in the future, we can find an alternative resource like green resources – spodumene. The first step is to identify the field with minerals - prospecting, then the second is exploration, and culminates with exploitation. In Romania, we find probably the only fields with lithium pegmatites in Conțu. Pegmatitic bodies are known as Conțu Superior and Conțu Inferior. Spodumene appears in the form of crystals and massive aggregates, with long habitus – prismatic, sometimes tabular, and with dimensions of 25 cm – 70 cm. Its color varies from white–greenish with vitreous luster, to gray – greenish, color due to the alteration processes, which led to the appearance in green – yellow colors on the spodumene has a good cleavage on the plane (010). Spodumene has monoclinic symmetry and C2/c space group (15), and cell parameters: a = 9.466 Å, b = 8.394 Å, c = 5.221 Å. The analytical method (EPMA) indicated a lithium oxide content between 7.43 % and 7.50 %, these percentages were calculated. Beryl (the emerald variety) macroscopically, has a greasy luster, colors in light green to dark green tones, in the mass of quartz and albite. Beryl crystallizes in the hexagonal system, space group P6/mcc (192), and the cell parameters are a = 9.267 Å, b = 9.187 Å. Infrared transmittance spectroscopy indicated the presence of beryl. BeO4 vibrates at frequencies around 900 cm-1 and 1000 cm-1, we find in sample N118, valence vibrations at: 1094 cm-1, 1039 cm-1, and 957 cm-1.","PeriodicalId":55272,"journal":{"name":"Carpathian Journal of Earth and Environmental Sciences","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2023-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49509458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study consists of two interconnected parts. The first part demonstrates the application of the geodiversity evaluation method using the geodiversity index, whereas the second part deals with the evaluation of the geoheritage objects of the studied area. The methodology for calculating geodiversity index that was applied in this research was modified due to the size of the studied area. The geodiversity index is calculated based on the number of abiotic elements and the roughness of the relief within the studied area. Mount Rogozna, with an area of 818.26 km2, has been studied and processed using a network of spatial polygons of 500 × 500 m and using different maps. The second part of the research deals with the evaluation of geoheritage objects, applying the Geosite Assess-ment Model. The obtained results demonstrate that geoheritage objects are not always located in places with high values of the geodiversity index. This is proven by the fact that 5 out of 7 geoheritage sites are located in areas with low geodiversity values. The obtained qualitative and quantitative data with maps showing the distribution of geodiversity can serve as a starting point for the development of a planning and management strategy, but also as the example of good practice for possible further application in the quan-tification of geodiversity in this part of Serbia, and beyond its borders as well.","PeriodicalId":55272,"journal":{"name":"Carpathian Journal of Earth and Environmental Sciences","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2023-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43501628","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the order to predict the Hg distribution for the whole study area, the interpolation methods were used in GIS. The plant material consists of 4 plant species: Calamagrostis epigejos, Lotus corniculatus, Leontodon hispidus and Picea abies. The samples were dried, grained, dissolved in HNO3 and HCl solution and consequently measured by inductively coupled plasma mass-spectrometry (ICP-MS) for Hg content. The results show a mass contamination of the dump top-soil horizon by mercury. The values in soil variable from 16 to 910 mg kg-1. The bioaccumulation potential of some investigated plant species can be considered as significant as well. The highest concentration of Hg was found in Picea abies ─ 24 mg kg-1.

In this study, different physiographic units of Atabey Plain have developed soils with varying characteristics. The variability in land use and fertilizer input management causes changes in the availability and geochemical fractions of phosphorus. In this study, 29 surface soil samples (0-20 cm) were taken from various fruit orchards to investigate the plant cover-related inter-fraction mobility and availability of P as a function of soil characteristics. Sequentially extracted geochemical P fractions were: sodium bicarbonate [NaHCO3-P (organic Po, inorganic Pi, and Total Pt)], sodium hydroxide [NaOH-P (Po, Pi, and Pt)], citrate bicarbonate dithionite (CBD-P), hydrochloric acid (Ca-P), and residual (Res-P) phosphorus. In order to study the relationship of phosphorus fractions with soil properties, chemometric analyses were performed. According to the results, the average concentrations of the fractions in descending order were: Ca-P (200-1029 mg kg-1) > Res-P (55.3-449 mg kg-1 ) > CBD-P (56.5-204 mg kg-1) > NaOH-Pi (26.0-206 mg kg-1) > NaHCO3-Pi (4.38-93.4 mg kg-1) > NaOH-Po (0.55-30.0 mg kg-1) > NaHCO3-Po (0.26-7.56 mg kg-1). The added fertilizer P was likely to be converted to NaOH-P in the short term and Ca-P and/or CBD-P for a relatively longer time. It was determined that the fractal distribution of these fractions varied according to the land use pattern and soil properties such as texture, organic matter, carbonates, and iron and manganese oxide minerals.","PeriodicalId":55272,"journal":{"name":"Carpathian Journal of Earth and Environmental Sciences","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2023-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47626425","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, to produce urban flood hazard (FH) maps downstream of the Strâmtori-Firiza reservoir (S-Fr) in NW Romania, a multi-scenario approach based on LiDAR-derived DEM integration, 2D hydraulic modeling, and remote sensing (RS) data validation is provided. In this context, to assess the flood control capacity (FCC) of the S-Fr hydro-technical system, three flood tests based on S-Fr flow rate with 5% (167 m3/s), 1% (270 m3/s) and 0.1% (447 m3/s) return periods were performed. The flood impact within the urban area of Baia Mare located downstream of S-Fr was achieved for each flood scenarios using four spatial data derived from the RAS Mapper module: flood extent (FE), flood depth (FD), flood velocity (FV) and flood hazard (FH). The results indicate that a large area of Baia Mare city can be affected by a potential flood caused by a dam failure and also contribute to the APDF update of S-Fr dam.","PeriodicalId":55272,"journal":{"name":"Carpathian Journal of Earth and Environmental Sciences","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2023-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49620270","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Różanka spring characterized by greater discharge variability than the fissured porous outflow in Szczytna. The latter one, due to the slower rate of water filtration in the rock medium, belongs to stable springs in terms of discharge. The local groundwater reservoir located in sedimentary rocks characterized by a much higher value of the groundwater volume stored (264,000 m3) than the reservoir consisting of weathered and fractured crystalline rocks (1,918 m3).

Long-term knowledge (i.e., centuries or millennia) of fire regime history and forest fire ecology and dynamic in local environments is necessary for sustainable ecosystem management and biodiversity conservation strategies. Charcoal is a widely used proxy for reconstructing fire regime history and vegetation burning. Charcoal analysis is based on the accumulation of charred particles in depositional environments such as lakes and bogs, during and shortly after the occurrence of fire events. Ombrotrophic peat bogs are sensitive to local environmental changes and, given that the deposition of allochthonous material is exclusively atmospheric, they are ideal archives for reconstructing charcoal fluxes resulting from biomass burning. This study quantifies charcoal abundance (number) in a peat sequence extracted from Tăul Mare ombrotrophic peat bog (Văratec Massif, Lăpuş Mts, north-western Romania) aiming to reconstruct local fire history over the last 3000 years and to explore potential drivers. As a novelty, observations concerning the morphology of charred fragments are added to provide additional information on the type of material burnt (woody vegetation or herbs), fire severity and charcoal source area, thus strengthening the interpretation of the charcoal record. Results showed moderate fire activity between 3000 and 2300 cal yr BP, which slightly decreased between 2300 and 700 cal yr BP and varied considerably throughout the last 700 years. Several major fire episodes were further identified around 2500, 1700, 1300, 900 and 500 cal yr BP. Of these, the first four overlapped two phases of progressive landscape opening and extension of pastoral activities, while the latter was unprecedented in the entire history of the bog and was likely associated with the development of mining activities in the area. This study provides the first complementary use of charcoal morphologies in fire history reconstruction in Romania and adds a valuable perspective on the extent of past human impact on the mid-elevation mountain landscape.","PeriodicalId":55272,"journal":{"name":"Carpathian Journal of Earth and Environmental Sciences","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2023-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41965994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Soil respiration, as a direct way to estimate edaphic microbial activity, could be a measure of the fluctuations of carbon stocks in soils. To determine the ability of soil respiration to evaluate such fluctuations we used soils with an increased content of organic carbon, constant optimal conditions, to eliminate the disturbing factors, analyzed in a short period of time. The influence of the specific decomposition rates of these soils was assessed by both spot determinations of soil respiration and analyzing the flux of CO2 from ex situ soil samples, under standard experimental conditions, to highlight carbon storage in such soils. Reference data can be accumulated through the analysis of these parameters, which compared with the results of quantitative/qualitative determinations regarding the changes in the content of microbial biomass, the content of fulvic sub-fractions, the fluorescence of dissolved organic material and the evolution of the content of siderophores, could be considered, by their own evolutions, as arguments in sustaining the use of respiration in the efficient estimation of carbon storage evolution in the soils. The analyses of these parameters were carried out in two phases, for comparing initial and final data of experiment (after 30 days). The soils had different levels of the respiration potential between phases. The level of soil respiration was reduced in time between 4.27-14.60%, in each soil. The CO2 flux showed, in time, a continuous decreasing trend in both soils. In the case of Mollic Histic Gleysol (Salinic), the coefficient of determination has the value R2=0.92 for the flux determined in the final phase. The levels of microbial biomass of both soils were increased significantly at the end of the experiment. In the case of Mollic Histic Gleysol (Salinic), microbial biomass increased from 456±23.12 μgC∙g-1 to 514±24.57 μgC∙g-1 soil. The fulvic sub-fractions A-D of both soils revealed significant accumulates of soluble organic compounds, with different molecular weights and complexity levels, after 30 days of incubations in standard conditions. The fluorescent components present in the water-extractable organic matter were highlighted by imagistic method. The highest degree of storages of newly bio-synthesized compounds of carbon was registered in organic matter of Mollic Histic Gleysol (Salinic). The intensity of siderophores biosynthesis increased over time, starting from an initial lower presence in the Mollic Gleysol (Salinic) (with Ø 11 mm halo), which were followed by an increasing of siderophores content and availability of iron, at the end of the experimental period.
