鲁西碱性岩-碳酸岩型稀土矿稀土元素赋存状态及矿床成因
Occurrence and Origin of Rare Earth Elements in Alkali-carbonate Rock Type Rare Earth Deposits in Western Shandong Province
摘要
Abstract
Weishan-Zibo area in western Shandong province is an important metallogenic belt and favorable prospecting area of alkali-carbonate rare earth deposits in China.Nine rare earth deposits(spots)have been discovered with good prospecting potential.However,there are few reports on the microscopic miner-alogical characteristics of rare earth minerals in the deposit,especially on the occurrence of rare earth ele-ments.In this study,the occurrence and regularity of rare earth elements have been studied by electron probe.It is considered that a small number of independent minerals,such as bastnaesite and bastnaesite were formed in the late stage of magmatic evolution,accompanied by celestite and other minerals.A large number of rare earth minerals,such as bastnaesite and bastnaesite were formed in hydrothermal activity stage after magmatic period.From the aspects of temporal and spatial distribution,structure and magmatic rocks,the ore-controlling factors of rare earth deposits(spots)in western Shandong province have been analyzed,and a metallogenic model of alkaline rock-carbonate rare earth deposits has been established,including partial melting of carbonate rock mantle induced by upwelling of the lithosphere and the inherit-ance of magmatic hydrothermal mineralization.关键词
