Аннотация

Dating of seafloor massive sulfides (SMS) forming on the ocean floor is a complex task, largely due to the multistage deposition of ore minerals and the influence of changing physicochemical conditions on the isotopic geochemical system during the interaction of hydrothermal fluids with host rocks and near-bottom seawater. Based on data obtained for the ultramafic hosted Semenov-5 field of the Mid-Atlantic Ridge (MAR), the possibilities and limitations of the 230Th/U method are demonstrated, particularly concerning the formation of the radiometric system in environment above and below the paleo-seafloor level. Age of surface ores is ranging from ~60 to ~8 thousand years. However, dating of subsurface sulfides was not possible due to the minimal input of near-bottom seawater in the deposition process beneath the seafloor. The study indicates that massive sulfides formed beneath the seafloor are of metasomatic origin, suggesting that massive sulfide mineralization may not be confined to the paleo-seafloor but could extend to greater depths. This finding has significant implications for other sulfide deposits within the MAR as well and may lead to a reassessment of their resource potential. The age dating of SMS from Semenov-5 field is comparable with other fields within the Semenov cluster. The data obtained highlight the long and complex history of hydrothermal circulation and massive sulfide formation within ultramafic rocks of ocean core complexes in slow-spreading mid-ocean ridges.
