Abstract:

There have been few reports about relationship between calcium isotope in cold seep system of sea floor and gas hydrate formation. The current study showed that calcium isotope fractionation at cold seeps was controlled by multiple factors and processes. Porewater and carbonate calcium isotope measurements may therefore offer potential to identify the location and intensity of anaerobic oxidation of methane (AOM) processes. It is also used to discuss control mechanism of calcium isotope fractionation at cold seep. This paper overviewed the basic characteristics and the research status of cold seep system and advance in research of calcium isotope tracer, and analyzed the relationship between the formation and evolution of cold seep system and gas hydrate. The major problems were also proposed in calcium isotope research. There will be some reference for further study of cold seep system and gas hydrate for domestic scholars.

Key words: cold seep system, calcium isotope, gas hydrate
