| 英文摘要 | The Bayan Obo deposit is the world's largest REE-Nb-Fe deposit and holds a pivotal strategic position in China. In this paper, detailed field geological survey and geochemical composition analysis of the REE bearing dolomite, different types of REE-NbFe ore and K -rich slate in the Main Orebody and East Orebody of the Bayan Obo deposit reveal the spatial distribution of the ore forming elements REE, Nb and the main alteration elements Na, K, F, P. The results show that the Main Orebody has a higher REE content than the East Orebody. The ore bodies have a significant enrichment of REE ( especially MREE and HREE) from the periphery to the center and from the shallow to the deep, and the deep part of the ore bodies have a greater exploration potential for MREE and HREE. The anomalous range of the ore -forming element Nb is consistent with that of the HREE, indicating a close symbiotic relationship between them. The anomalous range of the altered element F is consistent with the distribution range of REE-Nb-Fe ore bodies, and is an important precipitation ore -forming element. The anomaly of the alteration element P significantly exceeds the distribution range of REE-Nb-Fe ore bodies and is an important migration carrier element. Sodium alteration mainly occurs in REE bearing dolomite in the foot wall of the ore body, representing the early high -temperature alteration process. Potassium alteration is mainly developed in the K -rich slate on the hanging wall of the ore body, representing the late low -temperature alteration process. Potassium alteration, fluoritization, and phosphorus anomalies are the main shallow and peripheral indicators of carbonatite type REE deposits. |
