一、前言多数稀有元素的工业价值,或者潛在的工业价值,只到近十余年来才引起人們的注意。而与碱性岩有关的稀有元素矿物原料,更是近几年来才开始获得广泛的重视的。許多稀有元素在地壳中的含量并不比常見的一些金属元素稀少,并且許多稀有元素在碱性岩中或与其有关的地貭体中还有很高的富集,有时可以形成有工业价值的矿床。近年来的研究证明:与碱性岩有关的稀有元素矿床种类很多,分布相当广泛,規模也可以很巨大,特别对于某几种稀有元素来說,与碱性岩有关的矿床几乎是最有远景的。
I. INTRODUCTION The industrial value of most rare elements, or potential industrial value, has only caught the attention of more than a decade. And alkaline rock-related mineral elements of rare elements, it is only in recent years began to receive widespread attention. Many rare elements in the earth’s crust are not as scarce as some common metal elements and many rare elements are abundant in alkaline rocks or associated geoducts and can sometimes form industrial deposits . In recent years, studies have shown that: Alkaline rocks related to the rare element deposits of many types, a wide range of distribution, the scale can be huge, especially for some rare elements, alkali rock related deposits is almost the most promising of.
