It was the study of chondrites that allowed researchers to work out how old the solar system is 研究者通过研究球粒状陨石而得出太阳系的年龄。

To reach back , you need to look in the dust grains in chondrites , rather than at the chondrules 如果是追溯太阳系形成之前，你需要研究球粒状陨石中的灰尘颗粒，而不是陨石球粒。

Chondrite normalized ree distribution patterns for the core q43 are comparable to those of the sediment of changjiang river and huanghe river delta 球粒陨石标准化后的稀土元素具有与长江、黄河、黄土等上陆壳沉积物相一致的特征。

The average composition for our sample is different in some ways from the ci chondrite meteorites : namely we found more zinc , gallium , and copper , and less sulfur 我们样品的平均成分水平在某些方面与ci球粒陨石不同：即我们发现有较多的锌、镓和铜及较少的硫。

Even after making generous assumptions , we determined that the maximum temperature reached in carbonaceous - chondrite asteroids with a diameter of 80 kilometers or more would be only 670 degrees c , too low to cause any melting at all 即使给予很宽松的假设，我们认为直径在80公里或以上的碳质球粒陨石小行星，达到的最高温度只有670 ，不足以造成任何的熔化。

Thermal models show that even if the asteroids assembled immediately after the formation of the chondrules , 26al heating would have raised temperatures in the interiors of ordinary - chondrite bodies to a maximum of 1 , 100 degrees c ? high enough to cause melting of metals and sulfides but too low to melt silicate minerals extensively and differentiate an asteroid 热模型显示，即使小行星在球粒形成之后立刻聚合，铝26的加热最多也只能将普通球粒陨石内的温度提高到1100 ，虽可使金属和硫化物熔化，但并不足以将矽酸盐矿物大量熔化并造成小行星各层分异。

Comparative studies of ree geochemical characteristics of various geologic bodies in the deposit indicate that the various ores and alkaline volcanic rocks contain abundant ree , specially lree the chondrite - normalized patterns of both ores and alkaline volcanic rocks show a strong lree enrichment and positive eu anomaly , in contrasting with the dolostones which show slight lree enrichment and moderately negative eu anomaly 同期成矿流体从早期到晚期(块状矿石条带状矿石) ，轻重稀土分异变小，稀土总量增加，条带状矿石中稀土含量最高;矿石黄铜矿6345值变化在一0 . 3编到2 . 8 % 。范围，显示慢源硫特征;菱铁矿6 ’ 3c ( 8 % 。
