Recently, a research team led by Associate Professor ZHANG Yong at the Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences (NIGPAS), investigated the Troodos ophiolite in Cyprus (Fig.1). By integrating rock magnetic measurements, triple oxygen isotope analyses, mineralogical observations, and major-element geochemistry, the researchers identified serpentinization processes associated with different tectonic stages and established links among fluid sources, reaction temperatures, Fe redistribution, magnetite formation, and rock magnetic properties. These findings provide new constraints on the mechanisms responsible for the formation of secondary magnetic minerals during chemical remagnetization. The results have been published in the international geoscience journal Geology.
