Petroleum generation and migration in submarine hydrothermal systems; An overview
Abstract
The conversion of organic matter to petroleum by hydrothermal activity is an easy process,occurring in nature in many types of environments. Geologically immature organic matter of mariner sediments is being altered by this process in Guaymas Basin (Gulf of California), Escanaba Trough and Middle Valley (northeast Pacific), Bransfield Strait (Antarctica), and Atlantis II and Kebrit Deeps (Red Sea). Contemporary organic detritus and viable microorganisms are also converted in part to petroleum-like products by the same process when present to become entrained, as for example on the East Pacific Rise at 13{degrees}N and 21{degrees}N and on the mid-Atlantic Ridge at 26{degrees}N. The hydrocarbon products (methane to asphalt) generated in all these areas have been elucidated in terms of composition, organic matter sources, and analogy to reservoir petroleum. This petroleum represents a major input of carbon to the primary chemosynthetic productivity of hydrothermal vent systems and may be important to interactions with metals in hydrothermal ore formation.
