Abstract

A NYF-type (Nb-Y-Zr-F) Khaldzan-Buregtei pegmatite containing rare-earth metals occurs within alkali granitoid complex of the western Mongolia. The pegmatites are considered as differentiates of syenites and alkali feldpar granitic rocks, showing that their rare-earth element concentrations are enriched tens times higher than those from the adjacent alkali granitic rocks. It is suggested that econemic aspects of the pegmatites can be controlled by the magnitude of lateral and vertical extensions and local grade variation of REE-bearing pegmatites.

몽골 서부 할잔-부룩테이 알칼리 복합체에서 산출되는 페그마타이트는 Nb-Y-Zr-F의 부화가 특징적인 NYF 유형의 함희유금속 페그마타이트이다. 이들 함희유금속 페그마타이트는 할잔-부룩테이 섬장암 및 알칼리 장석 화강암의 분화물로서 알칼리 화강암류에 비해 십 배 이상의 희유금속이 농집되어 있다. 할잔-부룩테이 함희유금속 페그마타이트의 경제성은 페그마타이트맥의 연장성 및 국부적 품위 변화에 의해 좌우될 것으로 생각된다.
