Abstract

Abstract

X-ray diffraction (XRD), major and rare earth elements (REEs) geochemical characteristics of samples in a weathering profile from Guangxi were studied in order to reveal the geochemical behaviors of REEs during weathering. The profile can be divided into four layers from surface downwards: the humic layer (A₁), the sub-clay layer(A₂), the net-veined weathered layer (B₁), and the completely weathered layer (B₂). Clay minerals and chemical indexes of alteration (CIA) rapidly decrease from top to bottom. Samples from A₁, A₂ and B₁ are enriched in Ce, Nd and heavy REE relative to their parent rocks. All samples are depleted in ion-exchangeable heavy REE and are relatively enriched in Y. Ion-exchangeable light and heavy REEs are enriched in the completely weathered layer. The ion-exchangeable REEs in the weathered granite are sourced mainly from labile REE-bearing minerals, such as allanite and titanate. The enrichment of heavy REE in samples from A₁, A₂ and B₁ may have been caused by the residual zircon and xenotime, or the formation of supergene mineral, such as churchite-Y. The degree of weathering of granite leads to the change of the fractional degree of ion-exchangeable light and heavy REE.
