【摘要】 本文简要介绍了海底热水成矿作用的基本概念,重点探讨了现代海底热水成矿作用最新流行的几种成因模式及其油气意义,从理论与实践的结合上较详细地阐述了对流核和地震泵成矿模式的地质环境、成矿物质来源与过程、流体性质及其演化,指出现代海底热水成矿作用中有两点是重要的,即岩浆与海水发生的水岩作用及含矿热水和海水的混合作用。在此基础上深入分析了海底热水金属矿床与油气矿藏独特共生的现象,并对海底热水系统内富CO2-烃类流体的形成、演化及CO2-烃类-金属相互作用问题做了一些讨论,旨在引起人们对现代海底热水成矿作用及其油气勘探研究工作的重视。更多还原

【Abstract】 The paper briefly introduces the fundamental concept of modern submarine hydrothermal mineralization.Aiming at its some latest prevalent genetic models and oil-gas significance,it expounds convection kern, seismic pump models in light of theory and practice in detail,which not only display geological environment,metallogenic material source and process,fluid character and evolution,but also emphasize water-rock interaction of igneous and seawater and compositing of pay thermal water and seawater importantly.Therefore,it closely analyses distinct symbiosis of seafloor hydrothermal metal deposit and oil-gas ore reserves.The paper makes some discussions of CO₂-hydrocarbon fluid’s forms,evolution and CO₂-hydrocarbon-metal interaction in submarine hydrothermal system in order to attach importance to modern submarine hydrothermal mineralization and exploration significance of oil and gas.更多还原
