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.
本文介绍了南海西南部沉积物中自生硫化物(黄铁矿)的研究结果。该研究的材料是在R/V Akademik M.A. Lavrentyev (Cruise 88) (Shakirov等，2021)上进行的综合地质-地球物理考察中获得的。对黄铁矿的形貌和微观结构进行了研究。通过对黄铁矿中硫的同位素研究，阐明了硫化物的成因，首次证实了伏汉盆地硫化物的非生物成因。其他大多数硫化物地层的生物成因已通过地球微生物学调查得到证实。对黄铁矿组成和外加剂的研究表明，黄铁矿具有较高的镍含量。
期刊介绍：
Lithology and Mineral Resources is an international peer reviewed journal that publishes articles on a wide range of problems related to the formation of sedimentary rocks and ores. Special attention is given to comparison of ancient sedimentary rock and ore formation with present-day processes. The major part of the journal is devoted to comparative analysis of sedimentary processes on the continents and in oceans, as well as the genetic aspects of the formation of sedimentary and hydrothermal–sedimentary mineral resources. The journal welcomes manuscripts from all countries in the English or Russian language.
