在我国南方,广泛发育各种酸性岩浆侵入体,蕴藏着丰富的稀土、稀有和放射性元素等矿产资源。找矿勘探及地质研究证明,其中大部分与燕山期花岗岩体有密切关系。实际情况是只有部分燕山期花岗岩体中,上述有用元素能富集成矿,而在更多的燕山期花岗岩体中,并未发现有工业价值的矿床。铌钽矿化与钨矿化可在一地存在,也可在不同岩体中出现,但铌钽矿化、钨矿化与铀矿化经常不在一地。上述现象纯属偶然的巧合,还是某种内在联系的反映呢?含矿花岗岩与不含矿的花岗岩在化学元素组合上有没有差异?研究这个问题对今后的找矿和勘探显然是有重要意义的。
In the south of our country, a wide range of acidic magma invaders are developed, which contain rich rare earths, rare and radioactive elements and other mineral resources. Prospecting Exploration and geological studies have shown that most of them are closely related to the Yanshanian granite. The actual situation is that only part of the Yanshanian granite body, the useful elements can enrich mineralization, and in more Yanshanian granite body, no deposits of industrial value found. Niobium and tantalum mineralization and tungsten mineralization can exist in one place, but also in different rock mass, but niobium tantalum mineralization, tungsten mineralization and uranium mineralization are often not together. Is the above phenomenon an accidental coincidence or a reflection of an intrinsic link? Is there any difference in chemical element combinations between ore-bearing granites and non-ore-bearing granites? Studying this issue is clearly of great significance for prospecting and exploration in the future of.
