目前至少划分出12种岩浆建造,世界上大量的内生铁矿床与它们有关。研究结果表明,不同成因和不同建造的铁矿床除了以特殊的地质-矿物为标志外,还可根据钛磁铁矿和磁铁矿中混入元素的分布来加以区分。例如对个别建造的某些矿床类型来说,Ti、V、Mg是主要的。作者研究了Mg、Sc、Ti、V、Cr、Mn、Ni在钛磁铁矿和磁铁矿中的分布(表1)。对于Nb、Zr、Ga、Co、Zn、Ge作者认为也具同样的意义,但由于资料不足,表中没有包括进去。绝大部分混入元素的定量测定是根据光谱和化学分析。对比表中所列的结果可得出下列结论:
Currently at least 12 types of magmatic construction are delineated and a large number of endogenous iron deposits in the world are related to them. The results show that iron deposits of different origin and construction, apart from the special geological-mineral signatures, can also be distinguished according to the distribution of elements mixed into the titanomagnetite and magnetite. For example, Ti, V, Mg are dominant for some types of deposit that are individually constructed. The authors studied the distribution of Mg, Sc, Ti, V, Cr, Mn and Ni in titanomagnetite and magnetite (Table 1). The authors of Nb, Zr, Ga, Co, Zn and Ge also consider the same meaning, but due to lack of information, the table does not include it. Quantitative determination of most of the mixed elements is based on spectroscopic and chemical analysis. The results listed in the comparison table give the following conclusions:
