“…The L1 experiment dissolves mainly carbonates and removes trace metals adsorbed as surface complexes on soil particles (Sposito, 1989; Steinmann and Stille, (Steinmann and Stille, 1997;Stille et al, 2009). The recovery between the total content and the sequential extraction experiments is highly variable for the different elements (Fig.…”

“…Thus, most of the REE and P-bearing accessory minerals are strongly light REE (LREE) enriched. All the REEbearing phosphates observed in this carbonate weathering mantle are commonly observed in lateritic profiles developing on granitic rocks as primary (monazite, xenotime, apatite) or secondary (rhabdophane) mineral phases (Braun et al, 1990;1998;Stille et al, 2009;Berger et al, 2014).…”

“…is now commonly recognized as a main parameter that controls the mobility and enrichment of REE within these weathering profiles (Braun et al, 1998 and citations therein;Aubert et al, 2001;Stille et al, 2009;Berger et al, 2014 and citations therein). Until now, there are no combined isotope and trace element studies dealing with weathering mantles derived from carbonate rocks.…”

“…In the crust (granite, metamorphic and/or metasomatic rocks, and pegmatite), monazite and xenotime are the stable phases for light REE and heavy REE, respectively, while rhabdophane and churchite occurrences are almost exclusively encountered in soil [9][10][11][12][13].…”

Abstract:In order to understand the crystal chemical properties of hydrous rare-earth (RE) phosphates, REPO 4,hyd , that form at ambient temperature, we have synthesized REPO 4,hyd through the interaction of aqueous RE elements (REEs) with aqueous P at room temperature at pH < 6, where the precipitation of RE hydroxides does not occur, and performed rigorous solid characterization. The second experiment was designed identically except for using hydroxyapatite (HAP) crystals as the P source at pH constrained by the dissolved P. Hydrated RE phosphate that precipitated at pH 3 after 3 days was classified into three groups: LREPO 4,hyd (La → Gd) containing each REE from La-Gd, MREPO 4,hyd (Tb → Ho), and HREPO 4,hyd (Er → Lu). The latter two groups included increasing fractions of an amorphous component with increasing ionic radius, which was associated with non-coordinated water. RE all PO 4,hyd that contains all lanthanides except Pm transformed to rhabdophane structure over 30 days of aging. In the experiments using HAP, light REEs were preferentially distributed into nano-crystals, which can potentially constrain initial RE distributions in aqueous phase. Consequently, the mineralogical properties of hydrous RE phosphates forming at ambient temperature depend on the aging, the pH of the solution, and the average ionic radii of REE, similarly to the well-crystalline RE phosphates.

“…In addition, radiogenic isotope ratios are fractionated neither by low--temperature nor by biogenic processes, then their abundance in geological materials (i.e. minerals and rocks) depends upon: i) the initial radiogenic isotopic abundance, ii) on the age of the rock/mineral, and iii) on their parent/daughter isotope ratio (Dickin, 2005;Stewart et al, 1998;Stille et al, 2009). …”
