| Abstract | Phosphorus (P) is an important nutrient and has an important impact on global primary productivity. Presently, the dynamics of the P cycle in low sulfate, anoxic settings are largely unknown. In this study, the adsorption-desorption behavior of Fe-bound P, organic-P, loosely-bund P, detrital apatite P, and refractory P was described in the sulfate and methane transition zone (SMTZ) at site 973-4 in the cold-seep area of the Taixinan Basin, South China Sea. Results showed that the Fe-bound P and organic-P were influenced by sulfate-driven anaerobic oxidation of methane (SD-AOM) and metal-driven anaerobic oxidation of methane (MD-AOM), and subsequently, the Fe-bound P and organic-P were released as HPO42- into the pore water. Meanwhile, significant increases were detected in authigenic carbonate fluorapatite (P-C(FA)) and vivianite within the MD-AOM zone, which indicate that this zone is an important P-sink area. The MD-AOM plays an important role in the formation of P CFA and vivianite because MD-AOM provide the necessary HPO42- and Fe2+ for the formation of these minerals. Our findings have major implications for understanding the P cycle in low sulfate, anoxic settings and are important for understanding the influence of MD-AOM on the phosphate cycle. |
