| 摘 要： | 白云鄂博特大型铌、稀土、铁矿床,由于其矿物组成的多样性、地质构造的复杂性、成矿的多期性使之成为一类典型稀土矿床,成为研究稀土矿的天然实验室。尽管已有60多年的开采及研究历史,但其含铁及稀土的矿床建造机制仍具争议。本文通过搜集、整理国内外近几年来发表的有关赋矿岩性(白云岩、富钾板岩、富钠岩石及碳酸岩脉)的研究成果,结合笔者的认识,对各种不同观点进行了对比分析和总结,最终提出了白云鄂博碱性碳酸岩-热水沉积岩系的观点,为白云鄂博稀土矿的研究提供一定的参考价值。

| Abstract: | Giant Bayan Obo Nb-REE-Fe deposit has long been considered typical REE deposit due to its variety of mineral assemblages, complicated geological structure and multiple mineralizations, and an ideal laboratory for study of REE deposits. Its formation mechanism has been on dispute despite 60 years of production and research. This study analyzed and compared the different evidence for the ore-bearing rocks such as dolomitite, K-rich slate, Na-rich and carbonatite dykes by collecting and studying the recently published data. Based on the author's own study, one set of alkaline carbonatite-hydrothermal sedimentary rock was proposed for the mechanism of the ore-bearing rocks in the Bayan Obo deposit. This provides to some extent a reference value for research of the Bayan Obo REE deposit. |
