<title>Abstract</title> Mining activities have as a secondary result the production of residues stored in tailings dumps and ponds which lead to serious environmental hazards over time. For this reason, it is necessary install accelerate ecological succession on ponds, their phytostabilization being an ongoing challenge. The aim study was apply eco-technology already successfully demonstrated two tailing dams, third one with specific geochemical structure, knowing that each polluted area...
Representing a long-term source of revenue, an important job generator, and offering opportunities to increase life quality, tourism is considered priority for economic development in Romania from the national local levels. These reasons which minimum environmental impact reduced consumption natural resources could be added, recommend this domain as solution obtain gains within protected areas Romanian Carpathians (i.e. parks). Thus, key activity some most valuable fragile territories,...
Mining activities often generate important amounts of extractive waste, and as a consequence, environmental impacts that affects all factors to greater or lesser extent. Depending on variety variables, the impact can be permanent temporary, reversible irreversible, negative positive. This study conducted research status closure remediation processes mining areas in Romania, specifically counties Maramureș, Suceava, Harghita, Alba, Hunedoara, Caraș-Severin. Furthermore, based type level...

Natural samples of sphalerites containing Mn in the range 0 ≤ x 0.25 apfu from Săcărâmb Au–Ag–Te ore deposit, found Apuseni Mountains, Romania, were investigated using Raman spectroscopy to determine its capability provide estimates content. data for natural Mn-rich sphalerite have not been published so far, with largest concentration being Romanian territory (i.e., 14.1 wt.%). The results are good agreement SEM-EDS data. In this study, three genetic types identified: ferroan...
Large platy symplectitic aggregates composed of corundum and albite appear in quartz veins crosscutting heavily retrogressed eclogites the Căpățâna Mountains, South Carpathians. They were identified as pseudomorphs after kyanite initially formed veins. Protracted circulation reactive fluids alkaline composition along produced corundum-forming breakdown kyanite. Sluggish aluminium silicate – forming reaction between enabled metastable coexistence two incompatible minerals, which nevertheless...
The five-element mineralization of the Bihor metallogenetic district, Apuseni Mts., Romania contains three identifiable depositional stages, recording Co-fluctuations during a continuous increase sulfur activity. Gersdorffite forming several chemical clusters precipitates overprinting diarsenide-rich stage, later growing abundantly as krutovite-gersdorffite with nickeline, and replacing at different extents earlier assemblages. A Raman investigation on gersdorffites accompanying phases...
To get more data concerning de geochemistry and volcanology of Reykjanes Peninsula (Iceland) lavas, high-precision analytical methods such as Instrumental Neutron Activation Analysis (INAA), Electron Microprobe (EMPA), X-ray Fluorescence (XRF), Diffraction (XRD), ICP-MS, microtomography (XRMT) magnetism, coupled with mineralogical investigations were used. INAA, EPMA, XRF ICP-MS used to determine both major trace element mass fractions. In the case elements, despite some differences inherent...
This study offers a comprehensive analysis of unconventional renewable and sustainable energy production options by tapping into the associated with natural tendency to cancel salinity gradients that occur when salt water fresh come contact. Furthermore, this paper assesses potential for generating blue in Romania examining historical data on flow rates from relevant sources, such as Danube River, loading receiving bodies, including lakes, Black Sea. In addition, briefly references...
The three known polymorphs of nickel diarsenide were found to coexist in apparent equilibrium the five-element mineralizations Bihor Metallogenetic District. It is first identification pararammelsbergite and krutovite Romania, locality joins a very limited list occurrences where all NiAs2 coexist. Both phases newly identified Romania are easily distinguishable from rammelsbergite by their optical properties display consistent compositional differences manifested stoichiometry degree...
The issue of the cubic morphology chalcedony, in general, is still a matter debate, although pseudomorphism after melanophlogite gaining popularity. To address origin Trestia present study employed optical microscopy, XRD, FT-IR, micro-Raman, thermogravimetric and SEM methods which provided strong indication for melanophologite phase associated with investigated chalcedony. macro- micro-features samples, clear XRD diffraction pattern, as well spectroscopic detection CO2 SO2 support this...
