Nyegga麻坑区位于中挪威海大陆坡边缘Storegga海底滑坡的北缘,本研究的甲烷成因自生碳酸盐岩采自该麻坑区的CN03、Tobic、DoDo和G11四个麻坑内的海底面之上。碳酸盐岩孔洞和裂隙非常发育,部分碳酸盐岩胶结有大量的化学自养贝壳,表面被红褐色-黑色的铁锰氢氧化物覆盖。碳酸盐矿物以泥晶高镁方解石和针状文石为主导,伴有极少量的白云石。草莓状黄铁矿和球粒分布广泛,揭示了碳酸盐岩形成时的还原环境及形成过程中微生物的参与。碳酸盐岩的δ~(13)C_(PDB)值为-58.67‰~-47.46‰,清楚地表明这些甲烷成因自生碳酸盐岩经甲烷厌氧氧化过程而形成,且微生物成因的甲烷为其主导碳源。碳酸盐岩的δ~(13)C值还有效地指示了麻坑间沉积物甲烷的δ~(13)C值的差异。 |

Nyegga pockmark field is located at the northern flank of the Storegga Slide on the mid-Norwegian margin. The carbonate samples were collected on the seafloor inside the pockmarks CN03,Tobic, DoDo and G11. The carbonates are characteristic of a high abundance of various voids and fissures, and are covered by a thin black or red-brown coating of Mn/Fe hydroxides. Samples from Pockmark Tobic are cemented with numerous chemosynthetic bivalves. The carbonate minerals are predominated by micritic high-magnesian calcite and acicular aragonite, with little dolomite. Peloids and framboidal pyrites are abundant, indicating the reducing conditions and microbial-mediated processes during precipitation of the carbonates. The δ~(13)C_(PDB) values range from -58.67 to -47.46‰,clearly demonstrating that the carbonates are cold-seep carbonates derived from the processes of anaerobic methane oxidation coupling with sulfate reduction, and microbial methane is the dominant carbon source. Meanwhile δ~(13)C values of the carbonates effectively reflect the difference in δ~(13)C values of methane in the correspondent pockmarks. |
