The coastal area of the Kavala district, Northern Greece, is characterized by minerals enriched in rare earth elements (REE). present study focuses on mineralogy black sands from six different locations and comprehensive mineral chemistry REE-bearing minerals, allanite-(Ce), epidote, monazite, thorite, zircon titanite. Allanite-(Ce) most important carrier light REE (LREE) studied sands, reachin...

The Midcontinent Rift System of North America is a ?1.1 Ga large igneous province comprising mainly flood basalts and intrusive rocks. We present new data for the Pillar Lake Volcanics Inspiration Sill from northern edge in northwestern Nipigon Embayment. comprise ?20–40 m thick, flat-lying sequence mafic pillowed massive flows, flow breccia, hyaloclastite breccia. They are characterized by SiO...

On the example of the Epembe carbonatite-hosted Nb-Ta-LREE deposit, we demonstrate the use of hyperspectral reflectance data and geomorphic indicators for improving the accuracy of remote sensing exploration data of structurally-controlled critical raw material deposits. The results further show how exploration can benefit from a combination of expert knowledge and remotely-sensed relief, as we...

Investigations have been undertaken to provide constraints on the nature of geochemically active processes in the mantle and their effects on mantle evolution and magma generation. Three types of approaches have been implemented: (1) To study isotopic systematics and trace element abundances in young, mantle-derived volcanic rocks, which, because of their tectonic setting, had little or no chan...

Petrologic studies of igneous rocks often rely on whole-rock analyses alone to deduce source and melting histories. Whole-rock compositions represent a mixture of the processes responsible for the final texture and composition of the rock, but do not emphasize the evolutionary processes that the rock may have experienced. We examine the major, minor, and trace element compositions of plagioclas...

The Tinto and Odiel rivers (SW Spain) drain from a vast sulfide mining district join at 20-km-long estuary that enters the Atlantic Ocean. In this work, contents of rare earth elements (REE) fractionation in Neogene–Holocene sediment cores La Fontanilla cove (Tinto estuary) were studied. sediments collected depth 18 m different distances recent river flow analyzed for new information on tempora...
