Abstract
The results of studying natural samples of CuFeS2 chalcopyrite mineral from hydrothermal ore manifestations of island arcs of the Pacific Ocean by 63Cu nuclear magnetic resonance (63Cu NMR) in a local field at room temperature are presented. The asymmetric shape of the detected resonance lines in the 63Cu NMR spectrum indicates the presence of at least two overlapping lines. The presence of two overlapping central components can be a consequence of the occurrence of regions with different types of structural distortion near the resonant nuclei. These results show that the pulsed 63Cu NMR method can be an effective method for studying the physical properties of deep-sea polymetallic sulfides of the global ocean.
