The Relationship

The enrichment of Rare Earth Elements (REEs) in regolith depends on greatly number of chemical weathering degree, the ability of the ion-adsorption on clay, precipitation of REEs, minimum uptake by plants, and minor REE leaching out by lessivage. The degree of chemical weathering depends on the decaying of four base weathering elements (Mg, Ca, Na, K) in minerals and is relatively less dependent on the slow leaching of silica. Therefore, a study of regolith profile from weathering’s Adang Volcanics (western Sulawesi, Indonesia) is performed to understand the relationship between degree of chemical weathering, nature migration of REE and the characteristics of saprolitization REEs. The result of drill core samples shows the increasing of degree of chemical weathering (Degree of Saprolitization; DOS) is equal to gradual increasing of alumina by saprolitization, and has also gradual increase in Fe-Ti-oxides by ferruginization; furthermore, there is also a gradual enrichment of REEs occurred in the saprolite zone on Adang Volcanics regolith. The enrichment of REEs in the saprolite zones (E and B horizons) is 2.73 times (TREY = 2,579 ppm, in avg) compared to the parent mafic trachytic rocks (944 ppm) reveal the high adsorption ability on lateritic-ferruginous clay. The thickness of high concentration REEs (2,435 ppm, in avg) is starting from A to E, and B-horizon which is about 5 m. The ratio of LREE and HREE is 87.42% and 12.58%, respectively in parent rock which indicates the genesis of rare-earth is more influenced by replacement of Ca2+, Na+ and K+ in minerals of diopside, apatite and leucite/pseudoleucite rather than the substitution by zircon (Zr4+).

The Relationship

Forty-eight suspended particulate matter (SPM) samples were collected from the Mun River, northeast Thailand and its junction with the Mekong River, to investigate the relationship between the distribution of rare earth elements (REE) in SPM and the soils in the watershed. The total REE contents (∑REE) in SPM in the Mun River ranged from 78.5 to 377.8 mg/kg with the average of 189.3 mg/kg, which was lower than ∑REE of 222.3 mg/kg at the Mekong River (one sample at junction). The Post Archean Australia Shale (PAAS)-normalized ratios of light REE (LREE), middle REE (MREE) and heavy REE (HREE) were averaged to 1.0, 1.3 and 1.0, which showed a clear enrichment in MREE. In short, along the Mun River, the REE contents in SPM were decreasing, and the PAAS-normalized patterns of REE showed gradually flat. The REE content in SPM and soils are highest in the upper catchment, indicating that soil/bedrock is the most important source of REE in SPM. Additionally, the positive Eu anomaly was enhanced by the higher Ca content in SPM (R = 0.45), which may be caused by more feldspars or carbonates with Ca and Eu substituting Ca. The results present the REE behaviors of SPM in the Mun River and relationship between REE in SPM and soil/bedrock, the findings may support the other studies in catchment weathering.
