In this study, EPMA and LA-ICP-MS were used to determine the major and trace element concentrations, respectively, of apatites from Transhimalayan granitoids. The results indicate that F, Mn, Sr and REEs in apatites generally show good correlations with compositions of their host magmas and thus have high potential to be utilized as petrogenetic tracers. More specifically, F and Mn contents in apatites are covariant with the aluminosity of the host rocks so that can be used as an indicator for magma differentiation. Combining with Sr and REE data, which show significant variations in apatites from different rock types, these elements may be furthermore used to construct "discrimination diagrams" for more detailed investigations of complex petrogenetic processes such as magma mixing and compositional heterogeneity.

本研究中，电子微探以及雷射烧蚀感应耦合电浆质谱术分别被用以量测藏南火成岩中磷灰石的主量与微量元素含量，微区分析的结果显示，磷灰石的氟、锰、锶以及稀土元素均与岩浆源成分展现良好的对比关系，揭示了它们应用在岩石成因示踪上的优秀潜力：其中，磷灰石氟、锰含量的变化与原岩的铝饱和情形息息相关，因此可以作为岩浆分异程度的指标；而锶以及稀土元素则在不同岩石类型来源的磷灰石中展现了明显的丰度变化，因此综合这些元素将有机会进一步建立岩浆来源的「鉴别图」，甚而以此讨论岩石成因，例如：岩浆混合与源区组成的不均一性。

They not only occur in deep ocean basins such as in the central North Atlantic where they were deposited below CCD, but they extend up the continental slopes and rises, such as in the Alps, including the Gampu area , in the Carpathian Mountains (Austria, Slovakia, Poland, Romania), in Spain, in Turkey and in the Exmouth Plateau (Legs 122 and 123) in northwest Australia.The Upper Cretaceous reddish marlstones in Italy are particularly similar to the Upper Cretaceous Chuangde formation red beds in the Tibetan Himalayas. In summary, the Upper Cretaceous redbeds have several characteristic as follow:(1) very low TOC, only 0～0.3%;(2) wide distribution throughout the Neo-Tethys, from north Atlantic to the west, to Exmouth Plateau to the east;(3) Sedimentary environment of the red beds varied from oceanic basin, to slope/rise, to outer shelf.
