铁在各种地球化学过程中大规模地分散、运移和集中,十分活跃。它常以氧化物(磁铁矿、赤铁矿)等形式富集成矿床。在地球化学理论中,认为铁在酸性成矿热液中以氯(氟)络合物形式运移的看法十分流行。一些地质观察和实验研究结果也证明了这种观点。WT.霍塞和C.J.施内尔研究了高温时磁铁矿在水和HCl溶液中的溶解度,并进行了酸 Iron in a variety of geochemical processes in a large-scale dispersion, migration and concentration, very active. It is often in the form of oxides (magnetite, hematite) and other forms of enrichment of ore deposits. In geochemical theory, the belief that iron migrates as a chloride (fluoride) complex in acidic mineralization hydrothermal fluids is prevalent. Some geological observation and experimental results also proved this view. WT. Huse and C. J. Schnell studied the solubility of magnetite in water and HCl at high temperatures and conducted acid
