| 摘 要： | 大洋中脊海底热液系统的演化与成矿是复杂、综合的地质过程.归纳、分析了前人研究的资料认为,热源供给和热液活动构造体系是控制热液系统演化与成矿的关键因素.在快速扩张洋中脊热液系统中,岩浆的供给充裕,构造体系渗透性极好,演化时间较短,海底的热液循环输出过程可分为发生、持续和衰退3个阶段;在慢速扩张洋中脊热液系统中,岩浆的供给...

| Abstract: | Seafloor hydrothermal activity in Mid-Ocean Ridge has become one of hotspots in geosciences because of its valuable scientific researching significance.Hydrothermal systems at seafloor spreading centers are characterized by a complex interplay among magmatic,tectonic and biogeochemical processes linked by fluid circulation and heat transfer in the oceanic crust.It could be divided into three phases on the evolution of magma-controlled hydrothermal system,an initial phase,a living phase and a dying phase.The... |
