Sufficient supplies of critical raw materials (CRMs) for rapidly developing technologies, e.g., Li-ion batteries, wind turbines, photovoltaics, digitization, etc., have become one the main economic challenges EU. Due to growing import dependency and associated risk supply disruptions these from third countries, there is a need encourage their domestic production. This an important starting poin...

Idanre area which is situated within the Nigerian shield affected by orogenic activities accompanied emplacement of Pan-African granitoids. This paper presents a new information on geochemical behaviour Rare Earth Elements (REEs) and High Field Strength (HFSEs) Zr-Hf Y-Ho that can explain post magmatic processes relating to origin evolution granite. Zr-Hf, Hf-(Zr/Hf) Y-Ho, (Y/Ho)-Ho variation d...

The distribution and compositions of chevkinite-group minerals (CGMs) in the pantelleritic Gold Flat Tuff, Nevada, USA, are used to examine three aspects evolution tuff, which we feel general significance peralkaline magmatism. First, both chevkinite-(Ce) perrierite-(Ce) occur certain facies, although normally these phases almost invariably different igneous lithologies. Their co-occurrence tuf...

Coal deposits can provide novel stratigraphic markers for reconstructing the evolution history of a sedimentary basin and correlating successions. Age dating was conducted on zircons harvested from No. 6 coal seam within Heidaigou Mine, Inner Mongolia. Two-kilogram samples were taken, recovered analyzed U–Pb isotopic rare earth elements (REE). The REE results zircon grains showed that all enric...

Ion-exchange (IX) resins incorporating single functional groups (sulfonic or amino-phosphonic) and two phosphonic) were evaluated for selective recovery of Rare Earth Elements (REEs) from acidic mine waters (AMW). The composition AMW solution, complexing properties the group, acidity investigated as key parameters concentration separation REEs transition elements (TEs). Fe has to be removed ena...

Introduction – Lunar meteorite Northwest Africa (NWA) 032 is an unbrecciated mare basalt, discovered in 1999, whose modal mineralogy is characterized by phenocrystic olivine, pyroxene and chromite, with a groundmass containing feldspar, pyroxene, ilmenite, troilite and other trace metals [1]. Shock melt occurs in veins throughout the sample as well. Fagan et al. [1] observed that the major elem...

The contents of seven major components (TiO2, Fe2O3, MgO, CaO, Na2O, K2O and P2O5) and 15 trace elements (Sc, V, Cr, Ni, Cu, Sr, Y, Zr, Ba, La, Ce, Nd, Eu, Yb and Th) were determined by ICP-AE spectrometry in 27 samples of manganese nodules, micronodules as well as abyssal clay collected by dredging from an area of nearly 1,9802 nautical miles in the central Clarion-Clipperton abyssal plain at ...

Geochemical characteristics of greywacke and intercalated phyllites from Haveri and Dharwad block (long N 75° 10' to 75° 25' E and lat 15° 30' to 45° 00'S and (long 75° 05'E and lat S 15° 15' to 15° 35') of Shimoga basin have been studied to unravel the provenance and the tectonic setting of the greywackes. The greywackes are medium grained feldspatholithic and show presence of perthitic feldsp...
