随着板块构造的动力地球模型的出现,人们逐渐认识到大洋盆地本身就是热源和金属源。由海水与洋壳的置换反应得到的金属能够集中成金属矿床的。如果洋壳中没有裂隙,就不可能形成这种矿床。而洋壳之所以产生裂隙是因为洋壳从原始的熔融状态冷却到固态时发生收缩。随着扩张中心的形成而发生的洋壳运动和流体的压力也
With the advent of the dynamic Earth model of plate tectonics, it is gradually realized that the oceanic basin itself is a source of heat and metal. Metals derived from the displacement reactions of seawater and oceanic crusts can be concentrated into metallogenic deposits. It is impossible to form such a deposit if there are no fissures in the oceanic crust. The reason why the oceanic crust is cracked is that the oceanic crust contracts when it cools from the original molten state to the solid state. Oceanic crustal movement and fluid pressure also occur as the center of expansion expands
