“…On the other hand, monazite can be considered a weathering-resistant mineral in which the mobility of the REEs and associated elements is low; only under severe conditions, such as in the context of sulfide-mining areas, does the mobility of REEs increases with respect to their generally accepted low mobility (Fernández-Caliani et al 2009;Pérez-López et al 2015;Edahbi et al 2018). Lintjewas and Setiawan (2017) considered the question of the mobilization of these elements from minerals under weathering conditions and they noted that, as supported by Cocker (2012), during pedogenesis a relative enrichment of REEs in the weathering products in relation to bedrock is pronounced in horizon B. Jin et al (2017) studied the mobility of these elements during the weathering of shales and reported different degrees of mobility depending on the climatic conditions as well as mineralogical differences and different organic matter contents.…”

Monazite ((Ce, La, Nd, Th) PO 4 ) is a rare and strategic mineral that occurs naturally as an accessory and minor mineral in diverse igneous and metamorphic rocks. This mineral does not frequently form mineable ore deposits and it has different typologies, including those formed by endogenous processes (generally "yellow monazite" mineralizations) and those formed by exogenous processes ("gray monazite" mineralizations). The mineral is an important ore of Rare Earth Elements (REEs), which have been identified by the European Union as critical raw materials. Monazite can be considered a weathering-resistant mineral, and the mobility of the REE and associated elements is low. The study reported here concerns a mineralogical and geochemical assessment of the occurrence and risks associated with the presence of concentrations of monazite in a typical, well-developed, and representative red Mediterranean soil, in order to establish the associated risk with their future mining. The results confirmed that monazite ore is particularly poor in radioactive elements, and it is concentrated in the most surficial soil horizons. The chemical mobility of REEs present in the soil, as assessed by selective extraction with ammonium acetate in acidic media, follows the order Y > Dy > U > Tb > Gd > Eu > Sm > La > Th > Ce. The mobility of REEs contained in monazite proved to be higher than that of the REE compounds in the upper horizons of the soil profile suggesting the immobilization in other REE-containing minerals, while light REEs show lower mobility rates than heavy REEs, due to an immobilization of LREE by sorption with iron oxy-hydroxides. Further studies are required in order to obtain better speciation data for REEs in soils aimed to identify soluble and insoluble compounds.

“…The characteristics of hydrothermal fluids depend on the origin of the magma. REE mineralization occurs in some deposit types (Lintjewas & Setiawan, 2018;Murakami & Ishihara, 2008). REE deposits can broadly be divided in two categories, primary and secondary deposits.…”

“…Primary deposits are associated with igneous rocks relatively rich in LREE (Buyse, Dewaele, Decrée, & Mees, 2020;Lintjewas & Setiawan, 2018). At Tongo Gandima, the primary minerals containing REE in granitic rocks are monazite, xenotime, zircon, apatite, ilmenite as well as a variety of uncommon minerals.…”

is an area located in the southeastern part of the Bétaré Oya Gold district (Eastern Cameroon). Geochemical investigations on rare metals (TiO 2 , Th, Y, and rare-earth elements [REE]) were carried out on sample types (source rocks, unconsolidated fine-grained sediments, and concentrated sediments) using X-ray diffraction (XRD), X-ray fluorescence (XRF), inductively coupled plasma-mass spectrometry (ICP-MS), and scanning electron microscope equipped with EDAX spectrometer (SEM-EDS) methods. In this study, five layers of river terraces were selected (organic matter layer, clayey layer, fine sandy layer, coarse sandy layer, and gravel layer). One of them, the gravel layer, is mineralized. TiO 2 , Zr, and REE are more enriched in monzonites than in granites. Unconsolidated sediments derive mainly from the erosion of weathered materials developed on monzonites and granites. The mineral assemblage of fine-grained sediments from the gravel layer is muscovite, kaolinite, quartz, rutile, smectite, and others, and the average concentrations in Th, Zr, and Y are high. Fifty

“…REE in the geothermal region are strongly influenced by the hydrothermal mobility formed by sulfuric acid fluids that may be found at the top of a volcano or around caldera rings. This is a place of groundwater mixing with magmatic gas rising to the surface (Lintjewas and Setiawan, 2018 Figure 4. REE spider diagram for andesitic lava in Weh Island.…”

Geochemical characteristics of Sunda volcanic belt are recognized from each characteristic of Weh Island, Tabuan Island in Semangko Bay, South Sumatra, and Andaman Islands. Trace and rare earth elements (REE) are produced by fumaroles in a marine environment of submarine volcano of Weh Island characterized by barium (Ba) as an indicator of sea water influence in the mineralization process, while sulphide minerals do not occur in this area. REE pattern compared to Mid Oceanic Ridge Basalt (MORB) shows a characteristic of subduction tectonics and is distributed in shallow coastal water of high energy. Based on comparison of REE contents in all samples, it reveals that volcanism process causes REE enrichments either in the past or in recent. Geochemical characteristics of Tabuan Island in Semangko Bay reveal the occurrence of hydrothermal mineralization followed by pervasive occurrences of sulphide minerals in vein-type disseminations enriched in Au, Ag, Zn, Pb, Cu, As, Sb, Ba, and Mn. Geochemical characteristics of Andaman Islands reveal imprint of substantial subduction component in the form of sediment fluid and melt and fluid-induced subduction component derived from altered oceanic crust.
