近年来,通过对姑山铁矿床的深入研究,提出了两种不同的成因观点:一种认为该矿床属于火山-浅成矿浆型,即由铁质熔融体在浅成条件下充填堆积而成;一种认为属于火山-热液型,即在浅成条件下由含铁的水溶液析出铁矿物。我们认为,不同学术观点的争论,将有助于深化对姑山铁矿床成因的认识。为此,本文试图从地质特征、实验资料和热力学分析等方面对该矿床的形成条件作一探讨,希望对继续深入研究矿床成因及此类矿床的找矿工作有所帮助。
In recent years, through the deep research on the Gushan iron deposit, two different genesis propositions have been proposed: one is that the deposit belongs to the volcano-shallow ore-forming pulp type, that is, the iron melt is filled and filled under shallow conditions A; considered to belong to the volcano - hydrothermal type, that is, under shallow conditions from the ferrous iron precipitation of iron minerals. In our opinion, the arguments from different academic perspectives will help to deepen our understanding of the genesis of the Gushan iron deposit. Therefore, this paper attempts to discuss the forming conditions of this deposit from the aspects of geological characteristics, experimental data and thermodynamic analysis, hoping to further study the genesis of the deposit and the prospecting work of such deposits.
