| 1. | A lead isotope ratio data base of ancient chinese bronzes 夏商周青铜器铅同位素示踪研究数据库的构建 |
| 2. | Molding experiment on indicating meaning of lead isotopes in bronze 青铜器铅同位素指示意义的范铸实验研究 |
| 3. | The lead isotope compsition of ore suggested that the lead should mainly be derived from old sequence at depth 佛子冲矿田矿石铅同位素组成稳定,主要来自基底地层沉积物。 |
| 4. | In 2002 , wen et al . reported the contents of lead isotopes in 76 vietnamese timbals and 18 relative objects , but only single point measurement was made 摘要2002年韦冬萍等在对76面越南出土铜鼓及18件相关物件样品进行铅同位素测定时,用电子探针的方法进行了成份分析,但只作了单点测试。 |
| 5. | From the study of lead isotope , we know that the lava of erlangping is ocean lava - spilite keratophyre , it is the main origin of lead in time evolvement sequence and genesis 铅同位素研究表明本区二郎坪群的火山岩为洋壳火山岩?细碧角斑岩,在时间演化序列上和成因上它们作为pb的主要源岩。 |
| 6. | The tracing of lead isotopes indicates different matrixes of lead isotopes have great difference , which makes an pb isotope tracing is much easier to identify the sources of pb 中国地质大学(北京)博士论文弱信息铅同位素示踪发现,蛟龙掌矿区各地质母体铅同位素差异明显,利于进行同位素示踪。 |
| 7. | The test of sulfur and lead isotope of ores shows that mineralizing matter mainly comes from deep . the ore minerals are typical low - to - moderate - temperature hydrothermal minerals , such as stylotypite , galenite and chalcopyrite 对矿石中硫和铅进行同位素测定,认为硫主要来自深部,显示了地幔硫遭受少量地壳物质混入后的硫同位素组成。 |
| 8. | Through the study of characteristic of macroelement , microelement , rare - earth element , oxyhydrogen isotope , sulfur isotope , lead isotope , fluid inclusion etc , a conclusion can be drawn that metallogenic substance comes from the upper mantle with mixing of some substance from the upper crust latter . it is likely to have the same source with the surrounding rock 通过对矿床的常量元素、微量元素、稀土元素、流体包裹体特征、氢氧同位素、硫同位素、铅同位素等特征的研究,认为成矿物质主要来源于上地幔,与周围岩石存在着同源的可能性,后期有一定的上地壳物质混入,成矿作用有三期,分别与区内的花岗岩、二长花岗岩脉、云煌岩脉有关。 |
| 9. | According to the comparison and analysis of mineral composition and geochemical characteristics of trace element , sulfur isotope , hydrogen and oxygen isotope , lead isotope and rare earth element in the gold ore and the altered spilite from the deposits of huachanggou gold mine , it was confirmed that the gold ore had obvious succession of the basic igneous rock 摘要通过对铧厂沟金矿床金矿石和蚀变细碧岩矿物组成、微量元素、硫同位素、氢氧同位素、铅同位素及稀土元素地球化学特征地对比分析,得出金矿石对该基性火山岩存在明显的继承性。 |
