Mantle degassing process is controlled mainly by SCD model. 研究表明, MORB源和 OIB源玄武岩稀有气体组成差异强烈支持地幔双层结构的存在,地幔脱气过程主要受溶解度控制脱气模式 SCD控制; cnki Therefore, two of MORB- type and SSZ- type ophiolite crop out along collision belt formed after the closing of the old ocean. 从而,在古大洋消失之后形成的碰撞带上同时保存了 MORB型和 SSZ型两类蛇绿岩。 cnki Widely distribution of ancient depleted components in the asthenosphere suggests that DMMdepleted MORB mantle should not be synonymous with the MORB source. 亏损的地幔域在软流圈中的广泛分布表明亏损地幔 DMM并不等同于 MORB源区。 search.gucas.ac.cn MORB lava in these bodies may have been originated in back- arc basins or may represent relict fragments of normal ocean lithosphere. 在这些蛇绿岩中也有 MORB产出,可能是弧后盆地环境的,也可能有正常大洋岩石圈碎片的残留。 cnki |
