Cover Story: Coral tsunami boulders in Ishigaki Island, Japan showed a measurable intensity of remanent magnetization, although it is well known that corals skeletons have extremely weak remanent magnetization. To know what the origin of remanence is, in this study, we characterized magnetic assemblages in this coral skeleton to determine whether it is of biogenic or detrital magnetite using first-order reversal curve (FORC) measurements, ferromagnetic resonance (FMR) spectroscopy, and petrological observations through field-emission type scanning electron microscope (FE-SEM) with an acid treatment. Our findings indicate that the magnetic assemblage in coral tsunami boulders consists of biogenic-origin single-domain magnetites with a trace amount of detrital component. Therefore, fossil coral skeletons in Ishigaki Island have great potential for utilization for paleomagnetic studies. View this paper
