摘要

摘要: 白云鄂博REE－Fe-Nb矿床典型稀土氟碳酸盐矿物都具有碳酸根离子最特征的拉曼振动频率，并普遍出现有氟化物的拉曼光谱振动峰。利用子矿物的激光拉曼峰特征，结合矿物晶形和扫描电镜能谱分析结果，可以确定这些矿物可能为氟碳铈矿和氟碳铈钡矿，说明初始成矿热液中极富含稀土元素，矿脉内多相包裹体中含稀土元素的子矿物是从被包裹体捕获的流体中结晶出来的，是真正的子矿物，激光拉曼光谱仪可以作为鉴定流体包裹体中未知子矿物的较为可靠手段之一。

Abstract: Raman speetroscopy of typical rare-earth fluoro-carbonate minerals like cebaite, parisite and bastnaesite in Bayan Obo giant REE-Fe-Nb deposit shows vibration frequency of CO32- and F-. Raman speetroscopy of rare-earth daughter minerals in fluid inclusions shows that these minerals might be bastnaesite and cebaite, and presents that primary ore-forming fluids are enriched in REE. Rare-earth daughter minerals in multiphase inclusions in mineralizing veins were crystallized from trapped fluids, and are real daughter minerals. Laser Raman spectrometry can be used as a reliable tool to identify unknown daughter mineral hosted in fluid inclusions combined with mineral shapes and SEM-EDS analyses.
