| Metallogenic Mechanism and Ore-searching Prospect of REE (Fe, Ti) Polymetallic Deposits in Xuanwei-Luoping Area, Yunnan Province |
| In Xuanwei–Luoping area of eastern Yunnan Province, two REE, Fe, Ti polymetallic mineralized beds were discovered at the tops of paleoweathering crusts formed by two eruptive cycles of Permian basalts. The thickness of the ore-bearing beds is 8.0~35.0 m, and they contain ΣREO 0.016%~0.52%, TFe 10.09%~49.44% and TiO2 1.08%~10.94%. Mineralized bodies are widely distributed and assume stratified and stratoid forms. The formation of the mineralized bed experienced the metallogenic mechanism of initial source formation (basalts rich in REE, Fe and Ti) —transformation (leaching and infiltration of paleoweathering crust) —storage (stored in favorable paleogeographic environment), and hence this area has become a prospective area of great potential for REE, Fe, Ti polymetallic deposits. |
