Abstract
The paper presents the results of studying the authigenic sulfide aggregates (pyrite) from sediments in the southwestern South China Sea. Materials for the study were obtained during a comprehensive geological-geophysical expedition aboard the R/V Akademik M.A. Lavrentyev (Cruise 88) (Shakirov et al., 2021). The morphology and microstructure of pyrite were studied. Isotopic studies of sulfur in pyrite were performed to elucidate the genesis of sulfides, and the abiogenic nature of their formation was substantiated for the first time in the Fu Han Basin. The biogenic origin of most other sulfide formations was confirmed by geomicrobiological investigations. The study of the composition and admixtures in pyrite revealed a high Ni content in this mineral. [ABSTRACT FROM AUTHOR]
