Abstract

A recent paper published in Geophysical Journal International reports that the Late Palaeozoic to Early Mesozoic sedimentary rocks in the northeastern Okcheon belt of Korea were remagnetized during the Late Cretaceous to Early Tertiary, and argues that the remagnetization was triggered by fluids travelling more than 800 km from the subducting slab of the Kula/Pacific plates. Based on available geological data, however, we suggest that the remagnetization was caused by thermal effects of a Late Cretaceous pluton intruding the sedimentary rocks and/or associated 'short-range' hydrothermal fluids rather than by 'long-range' fluids.
