Jin et al. 2017 REE mobility and fractionation during shale weathering along a climate gradient

We systematically investigated six soil profiles developed on a climosequence of gray shale to constrain the mobility and fractionation of rare earth elements (REE) during chemical weathering processes. In addition, one site developed on black shale (Marcellus Formation) was included to document REE behaviors in organic-rich versus organic-poor shale end members under the same environmental conditions.
