Abstract:The formation mechanism of the large hydrothermal sulfide deposit is a complex geological process involving many controlling factors. Mixing between hydrothermal fluid and seawater plays a key role in this process. The results of the Ocean Drilling Program(ODP) indicate that mixing of the evolved seawater and hydrothermal fluid,which is wildly developed within the Trans-Atlantic Geo-Traverse(TAG) hydrothermal deposit,governs the internal structure and chemical compositions of the deposit to great extent. Ta...
