摘要:
钨矿的稀土元素地球化学可以反映成矿作用的条件和过程,为矿床成因提供有效的信息。中国钨矿床稀土元素地球化学的研究硕果累累,从单矿种角度进行全国性的系统总结十分必要。本文统计了1990年至2016年间不同类型钨矿床钨矿石矿物及与成矿有关岩体的稀土元素300多组数据。通过总结可知,不同类型钨矿床钨矿石矿物及与成矿有关花岗岩中稀土元素的总量和稀土配分曲线不同,这与成矿原始物质及成矿时物理化学条件的不同有关。不同类型钨矿床大部分具有Eu负异常的特征,显示成矿条件为较高温的还原环境;黑钨矿及其成矿岩体的稀土分配模式之间存在一定的依从关系,但是,黑钨矿中的稀土元素并没有随着岩浆-流体的结晶分异而富集。

Abstract:
The composition and characteristic parameters of rare earth elements (REE) in tungsten deposits provide mineralization environment as well as fluid and source information. The achievements in the study of geochemistry of rare earth elements in tungsten deposits in China are very abundant, but it is still necessary to make a national systematic summary from the perspective of single mines. In this paper, statistics of more than 300 sets of rare earth elements of tungsten deposits in different types of deposits published from 1990 to 2016 were investigated. The results show that total REE values and distribution curves in different types of tungsten deposits are different due to different sources and ore-forming physicochemical conditions. The Eu from different types of tungsten deposits exhibits negative anomalies, which implies that the ore-forming environment was somewhat reducing. There are some interrelations between wolframite and its ore-bearing granite, However, but REE in wolframite did not enrich with magma-fluid differentiation.
