摘要	Seep carbonates, formed by the synergistic metabolism of methane oxidizing archaea (MOA) and sulfate reducing bacteria (SRB), have been found in many places worldwide but have not been found to date in the South China Sea. Mud volcanoes and shale diapirs have been reported in the South China Sea however, and microscope and geochernical analysis of carbonates dredged where bottom simulating reflectors (BSR) suggest the presence of gas hydrate on the northeastern continental slope of the South China Sea suggest that the carbonates are hydrocarbon seep-related carbonates. The carbonates we dredged are chimney-like and preserve MOA/SRB fossils. Their very light carbon isotopic compositions (- 51.25 to - 51.76 parts per thousand) suggest that their carbon was derived from microbial methane oxidization. These seep carbonates and their preserved MOA/SRB fossils imply gas venting has occurred recently on the seafloor in the northeastern continental slopes in the South China Sea. (c) 2005 Elsevier Ltd.
