Abstract: In this paper, major elements, trace elements and Fe isotope composition of the magnetite quartzite, magnetite-rich ore and altered rock are presented. The average bulk compositions of the magnetite quartzite are characterized by high total Fe2O3 and SiO2, and low contents of Al2O3 and TiO2. The overall contents of trace elements and ΣREE in magnetite quartzite are very low. In the Post Archean Australian shale(PAAS) normalized REE patterns, samples display LREE depletion, distinct positive anomalies of La, Eu, Y, unobvious Ce anomalies, high Y/Ho values and heavy Fe isotope enrichment(relative to IRMM-014), which consists with the Fe isotope of oxidized and precipitated hydrothermal fluid. The geochemical charateristics of magnetite-rich ores are similar with those of the magnetite quartzite. However, ΣREE and Eu contents in the magnetite-rich ore are higher. Compared with magnetite quarterite, the magnetite-rich ore is characterized by the enrichment of light Fe isotope with larger range, which is similar to the altered rock. The magnetite quartzite is paleo-ocean chemical sedimentary rocks with devoid of terrestrial sediments, and experienced the oxidation and precipitation induced by the mixing of the submarine hydrothermal solution and the seawater. It can be deduced that the high grade iron ore was formed by the reworking of the low grade iron ore by the hydrothermal system with light Fe isotope enrichment, which resulted in Fe enrichment and Si depletion.

Key words: Fe isotope, rare earth element, genesis, Gongchanglingiron deposit, geochemistry
