The Proterozoic Athabasca Basin hosts a large number of high-grade, large-tonnage unconformity-related uranium (U) deposits, many which are also enriched in rare earth elements (REE). basin contains hydrothermal REE mineralization unassociated with U. Previous studies postulated that U and were derived from either the or basement; however, exact source metals remains ambiguous. This study provi...

In the Jebilet massif (Variscan belt, Morocco), two peraluminous granodioritic plutons (the Eastern and Central plutons) are spatially associated with a regional shear zone. The pluton includes Tabouchent, Bramram Bamega intrusions, which represent variably eroded portions of an arcuate apical part pluton. intrusions composed biotite ± cordierite-bearing granodiorite that is crosscut by tourmal...

Carbonatite intrusive complexes are important hosts for Rare Earth Elements (REE) deposits and commonly affected by surficial weathering processes. Mount Weld REE deposit of Western Australia is one the world’s richest here we present whole-rock mineral geochemical data on compositions primary weathered carbonatites. The concentrations in magmatic carbonatites at vary two orders magnitude, sugg...

To reveal the genesis of Makeng-style iron polymetallic deposits from SE China in paleo-Pacific tectonic domain, a new analytical method LA-ICPMS garnet U-Pb dating and rare Earth element analysis was conducted for Makeng, Luoyang, Dapai Pantian deposits. The results nine skarn samples these suggested that mainly formed during 137–130 Ma, which is consistent with zircon molybdenite Re-Os ages. ...

Abstract. The Black Forest hosts a wide range of hydrothermal mineralization, including fluorite–barite vein deposits. In detailed investigation the Finstergrund and Tannenboden deposits in Wieden mining district (southern Forest), diversity, geochemical evolution relative chronology multistage fluorite precipitation is tracked on basis rare earth element (REE) geochemistry, geologic field rela...
