morb meaning in Chinese
中央海岭玄武岩
Examples
- Based on our studies , the n - morb volcanic rocks were occurred in the pantiange area
金沙江带石鼓地区二叠纪火山岩具有裂谷火山岩的特征。 - Pb isotopic features imply that its source is similar to that of the indian ocean morb , and a dupal anomaly
Ph同位素特征表明其源区类似于印度洋morb的源区，具有dupal异常型的特征。 - It is presented that the hydrous fluxing as well as adiaba tic decompression plays an important role in melting of morb - like mantle beneath marina trough . compared with basalts from other back arc basins , it concludes that the magma varies from morb - like to arc - like with the evolution ; during the earlier stage of evolution , there coexist the two morb - like and arc - like lavas , it may be the nature of the magma in back arc basins ( especially in the earlier stage )
综合马里亚纳海槽和其他弧后盆地玄武岩的研究成果发现，弧后盆地特别是早期扩张的弧后盆地，其岩浆产物均具从似岛弧型到似洋中脊型玄武岩的时空演化特征；同时存在岛弧型和morb型两种熔岩，可能是弧后盆地(特别是早期扩张弧后盆地)岩浆作用的一个共同属性。 - The southern hainan mafic dykes are strongly enriched in lile with high nb / ta ratios , indicating a magma source reconstructed by silicic - melt through partial melting of ancient subducted slides . however , the northern hainan mafic dykes with chondritic nb / ta ratio should be derived from the fiuid - metasomatized mantle related to ancient subduction zone
琼南基性岩脉强烈富k _ 2o等lile和具有较高nb ta比值，其地幔源区应受到了古俯冲板片部分熔融形成的硅质熔体的改造；而琼中基性岩脉的nb ta比值接近于球粒陨石和morb值，应为古俯冲带含水流体交代的地幔源区的产物。 - This important tectonic zone parallel to the isotopic geochemical steep zone , which represented a suture line between the yangtze and cathaysian blocks . the geochemical evidence of the jianshui volcanic rocks from the sw part of shizong - mile zone shows that their lithologic types are tholeiites with the comparative flat ree patterns and enrichment in th , depletion slightly in nb , ta , and flat hfse . thus , they may be formed in a back - arc basin with the characteristics between morb and island - a
该构造带西南段的建水火山岩地球化学特征研究表明，该火山岩为拉斑玄武岩，具有较平坦的稀土分配型式， th较富集， nb 、 ta轻微亏损，高场强元素分布较平坦，具有介于岛弧和morb之间的地球化学特征，可能形成于弧后盆地环境。
