本文作者科特良尔认为,不同地质条件下形成的各种岩浆杂岩体和火山杂岩体按其含矿性而有所区别,含矿程度不一与这些岩石的分异程度有直接关系。通常,分异性最强的酸性或碱性岩浆岩都是含矿的岩石,尤以火山口及次火山岩含矿最为显著。火山建造的含矿性问题还处于早期研究阶段,但是完全有根据提出,在火山岩分布地区,特别是酸性岩和碱性岩分布的广大地区开展下列金属的普查工作:有色金属、贵金属、稀有金属和
According to Corteran, the authors consider that the various magmatic complexes and volcanic complexes formed under different geological conditions differ according to their ore-bearing properties. The degree of mineralization is directly related to the degree of differentiation of these rocks . Ordinarily, the most anisotropic acidic or basic magmatic rocks are ore-bearing rocks, especially in volcanic vents and sub-volcanic rocks. However, it is entirely based on the suggestion that the following census of metals be carried out in volcanic distribution areas, especially in the areas where the distribution of acidic rocks and alkaline rocks is widespread: non-ferrous metals, precious metals, rare metals with
