摘要
邯邢式铁矿成矿母岩即岩浆岩经过钠化除铁作用,其矿物成分、化学成分、磁化率及比重等发生一系列的变化,地质特征显著,形成钠化、磁铁矿和磁异常三者形影相伴的密切关系。钠化的范围、强度、规模与磁铁矿的大小规模成正相关,根据钠化能析出的铁质进行理论上的定量计算,将其结果与地质勘探所获铁矿石实际资源量相比,可以互相印证,为进一步就矿找矿、探边摸底、扩大范围、增加储量提供依据。因此研究钠化作用与接触交代型铁矿的成因联系,对今后在该区的找矿工作具有重要的指导意义。
The mother rock of Han-Xing type iron ore mineralization is the albitization and deironing magmatic rock with a series of change of its mineral component, chemical composition, magnetic susceptibility and the specific gravity and so on. Its geological characteristics are evident, and forms close association of magnetite with magnetic anomaly and albitization. The scope, intensity, scale of albitization is positively related with the scale of magnetite. A comparison of the result of theoretic quantitative calculation of iron matter origina- ted from albitization with the real mineral reserves of iron ores recovered by geological exploration can testi- fies the two results mutually and provides a basis for ore prospecting surrounding the existing orebodies so as to extend the scale and add more reserves at the bottom and the boundary of the existing ores, so a study on the genetic relation between albitization and metasomatic type iron deposit is of great significance for further prospecting in the region.
