Magnetite, one of the most important iron oxides, pervasively occurred among the igneous, sedimentary and metamorphosed rocks, and also presented in most of various deposits. Magnetite from Ernest Henry iron oxides copper and gold deposit with highest and lowest trace element concentration were inverstigated using laser ablation inductively coupled plasma mass spectrometry in this study. The cell parameters of correspondent magnetite were measured using X ray diffraction. We attempt to evaluate the variations of trace element concentrations of magnetite to the effection of the cell parameters. The re- sults showed that (1) substitution of a large range of cations can be induced because tetrahedral as well as octahedral positions are available in magnetite; (2) the trace element concentrations have an obvirous im- pact on changes of cell parameters in magnetite, and the magnetite with highest trace element concentra- tion has a smaller cell parameters compared to standard magnetite while the magnetite with lowest trace element concentration has a bigger cell parameters compared to standard magnetite, however, it is still unclear for the quality relationship between trace element concentrations and cell parameters.
