Hydrothermal Activity and its Effects on Sedimentary Organic Matter

摘要: The conversion of organic matter to petroleum products by hydrothermal activity is an easy process, occurring in nature many types environments. Geologically immature marine sediments being altered this process the Guaymas Basin (Gulf California), Escanaba Trough and Middle Valley (NE Pacific), Bransfield Strait (Antarctica), Atlantis II Deep (Red Sea). Contemporary detritus and/or viable microorganisms are also converted part petroleum-like when they become entrained turbulent mixing into discharging vent waters, resulting instantaneous hydrous pyrolysis. This latter case ubiquitous all systems, but can be studied fields without a sedimentary cover emanating directly from oceanic ridges, as for example on East Pacific Rise at 13°N 21°N Mid-Atlantic Ridge 26°N. hydrocarbon (methane asphalt) generated these areas have been compared terms composition, sources, analogy reservoir petroleum. In addition, type rep¬resents major input carbon primary chemosynthetic bioproductivity systems may important interactions with metals mineral ores.
