Chondrite normalized ree distribution patterns for the core q43 are comparable to those of the sediment of changjiang river and huanghe river delta
球粒隕石標準化后的稀土元素具有與長江、黃河、黃土等上陸殼沉積物相一致的特徵。 -
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
我們樣品的平均成分水平在某些方面與ci球粒隕石不同：即我們發現有較多的鋅、鎵和銅及較少的硫。 -
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
即使給予很寬松的假設，我們認為直徑在80公里或以上的碳質球粒隕石小行星，達到的最高溫度只有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
熱模型顯示，即使小行星在球粒形成之後立刻聚合，鋁26的加熱最多也只能將普通球粒隕石內的溫度提高到1100 ，雖可使金屬和硫化物熔化，但並不足以將矽酸鹽礦物大量熔化並造成小行星各層分異。 -
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
