AbstractThe northern South China Sea is a typical active cold methane seeping area and the seeping fluids certainly have critical impact on the geochemistry of the sediments. Two gravity cores, 1375- cm-long at Site 973-4 (with water depth of 1,666 m) and 935-cmq
Other Abstract南海北部东沙海域是典型的水合物成藏区,冷泉活动对其沉积物地球化学特征有显著影响。分析了东沙海域冷泉区973-4站位1 375cm(水深1 666m)和973-5站位935cm(水深2 998m)长的柱状样的总有机碳(TOC)、总硫(TS)含量,并挑选其中的底栖有孔虫进行了碳氧同位素测试。通过沉积物总硫含量分析和临近站位孔隙水数据分析表明,2个站位沉积物均有较浅的硫酸盐甲烷还原界面(SMI)深度和较大的甲烷通量,其中973-4站位硫酸盐甲烷界面深度为海水―沉积物界面以下约900cm,973-5站位硫酸盐甲烷
