chondritic meaning in Chinese
球粒状陨石的
Examples
- Because the chondritic asteroids formed after the chondrules did , the initial 26al to 27al ratio in chondrules places an upper limit on the amount of 26al that was available to heat the rocky bodies
因为球粒陨石小行星是在球粒之后形成，球粒中铝26对铝27的初始比值，决定了能够用来加热石质天体的铝26含量的上限。 - According to this scenario , researchers could never find evidence of such early chondrules because all these objects would have been destroyed by the melting of the chondritic asteroids into which they accreted
在这个情形下，研究人员恐怕永远也无法找到如此早期的球粒证据，因为所有这些物体在聚合的过程中，都会因为球粒陨石小行星熔化而被破坏。 - These investigations have found strong evidence for the former presence of 26al in the so - called refractory inclusions : tiny mineral assemblages , rich in calcium and aluminum , embedded in chondritic meteorites alongside the chondrules
这些研究发现了强而有力的证据，显示铝26曾经存在于所谓的耐火包体（富含钙和铝的细小矿物组合体，与球粒一起镶埋在球粒陨石内） 。 - 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。
