Abstract Monzogranite and syenogranite’s minor Eu anomalies and less fractionated REE patterns are governed by amphiboles with minor plagioclase crystallization. This feature illustrates the divergent impacts of minerals on Eu differentiation, including feldspars (which develop a negative Eu anomaly) and hornblende and alkali pyroxenes (which develop a positive anomaly). The geochemical analysis of the stream sediments of the study area showed that the REE trends of these minerals pointed to the same source or belonging to similar bedrocks, as well as an enrichment of light rare earth elements (LREEs) and a depletion of heavy rare earth elements (HREEs), along with the typical negative Eu anomaly that is characteristic of granitic magma. The concentration of REEs in the stream sediments is 11 times that of REEs in bedrock, showing the economic abundance that we can exploit. |
