洋壳是由地幔熔融物在扩张洋脊处的结晶作用形成的,熔融物携带的热会在传导和热液循环中消除掉。虽然热液流为海洋提供了一个重要的地球化学通量,但是人们对洋壳内热液冷却的分布了解得并不多(Schultz和Elder-field,1997;Mottl,2003)。我们对活动扩张脊进行地球物理、地质、岩
The oceanic crust is formed by the crystallization of the mantle melt at the dilatational ridges, and the heat carried by the melt can be dissipated during conduction and hydrothermal cycles. Although hydrothermal streams provide an important geochemical flux for the oceans, there is little understanding of the distribution of hydrothermal cooling in the oceanic crust (Schultz and Elder-field, 1997; Mottl, 2003). We expand the activities of ridges geophysics, geology, rock
