Demonstration of alpine structural phenomena at the structure of magnesite Deposit Jelšava - Dúbrava massif
Magnesite deposits in the Central Western Carpathians belong among the biggest deposits in the Europe. Their today’s structure is mainly the result of the Alpine orogenesis. During this period several deformation stages were active, which deformed the deposit body. This resulted in today’s complicated structure of the deposit. The genesis of deposit is still ambiguous; however, the importance o...
متن کاملassessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
magnesite veins from ultramafic massif of beni bousera (internal rif, morocco)
the magnesite veins are located in the beni bousera massif (internal rif, morocco), especially in tafidest region about 103 km sw of the tetouan city. they are hosted by perridotite and serpentinite formations. the aim of this study is to clarify the origin of this type of orre genesis. geochimical study of magnesite ore reveals that is a cryptocrystalline magnesite, formed by the co2-rich hyd...
متن کاملGeosynthetics in geoenvironmental engineering
Geosynthetics are planar polymeric products, which are used in connection with soil, rock or other soil-like materials to fulfill various functions in geoenvironmental engineering. Geosynthetics are of ever-growing importance in the construction industry. Sealing of waste storage facilities to safely prevent the emission of wastewater, landfill gas and contaminated dust as well as the diffusion...
متن کاملExperimental determination of the equilibria : rutile + magnesite = geikielite + CO 2 and zircon + 2 magnesite = baddeleyite + forsterite
The P-T conditions of both equilibria were determined precisely by reversal experiments in a piston-cylinder apparatus. On the basis of 8 experiments, brackets for the rutile-magnesite-geikielite equilibrium are 7.0–7.1 kbar at 800 ∞C, 8.6–8.7 kbar at 850 ∞C, and 10.5–10.7 kbar at 900 ∞C. On the basis of 9 experiments, brackets for the zircon-magnesite-baddeleyite-forsterite equilibrium are 7.1...
