1. The rare-earth element pattern tends to further approach Yangtze River via the normalization based on the North American shale, supracrust and chondritic meteorite.
    稀土元素经北美页岩、上地壳和球粒陨石标准化的配分模式趋向于和长江更接近。

2. Compositional variation of chondritic metal phase during thermometamorphism and melting of its parent body
    球粒陨石金属相在热变质及熔融条件下的组成变化

3. chondritic的意思

3. It seems reasonable that the Nandan iron meteorite should be classified to the group IAB. Further, it might be formed from the source matter with the chondritic composition, which experienced the impact and partial melting.
    指出南丹铁陨石似分为IAB群较合理，它可能是由具有球粒陨石组成的母源物质受冲击、经局部熔融而形成。

4.

4. 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。
