2012年8月19日,《自然——地球科学》(Nature Geoscience)发表了题为《大洋中脊下地壳结晶作用与熔融演化》的文章。文章给出了确定大洋中脊下地壳结晶作用发生位置及熔融演化的地球化学方法。该研究提供了位于太平洋的2个扩张中心(快速扩张的东太平洋隆起和中速扩张的胡安.德富卡洋中脊)大洋中脊轴下方结晶深度的直接地球化学证据。科学家测量了橄榄石熔融包裹体的挥发物浓度,以获得饱和蒸
On August 19, 2012, Nature Geoscience published an article entitled “Crystallization and Melt Evolution in the Lower Cretaceous Crust”. In this paper, the geochemical methods for determining the location and melting evolution of crustal crystallization under the mid-ocean ridge are given. This study provides direct geochemical evidence of the crystal depth beneath the mid-oceanic ridges of the two expansion centers in the Pacific, the rapidly expanding eastern Pacific uplift and moderate-velocity dilated Juan de Fuca mid-ocean ridges. Scientists measured the volatiles concentration of olivine melt inclusions to obtain a saturated steam
