A positive correlation was found between the solar activity and NO3- concentration in recent 1500 years. A long-standing issue of the nature of the solar activity during the Maunder Minimum was solved. An about 36a cycle was found in the solar activity. Low solar activity and weak geomagnetic field were responsible for the 36Cl peak at about 37ka BP. Climate change recorded in this ice core lagged insolation about 4ka during the last glacial maximum, about 1ka during the last deglaciation, and nearly 0ka during the Holocene.δ18O record also suggests that the variation in temperature on the Tibetan Plateau had some similar features to that in both Northern and Southern Hemispheres during the last deglaciation to some extent, which indicate that the tropics maybe play an important role on global climate change.
揭示出近1500a来古里雅冰芯中NO3-浓度变化可以反映太阳活动的强弱变化;回答了长期争议的并直接关系到太阳发电机理论是否正确的Maunder极小期太阳活动特征问题;发现太阳活动可能存在36a左右的周期;证实了37kaBP左右古里雅冰芯记录中宇宙成因同位素36Cl含量峰值的存在,指出这一时期的宇宙成因同位素峰值事件具有全球性,弱的太阳活动和弱的地磁场是这一事件发生的原因所在;揭示出古里雅冰芯记录到的"8.2ka BP事件",认为这一全球性事件发生的主要原因与弱的热盐环流和弱的太阳活动有关;发现古里雅冰芯记录的末次冰盛期和末次冰消期气候变化均在一定程度上滞后于太阳辐射变化,而全新世气候变化大致与太阳辐射变化同步;发现末次冰消期高原地区气候变化不仅具有北半球气候变化的某些特征,同时还具有南半球气候变化的某些特征,这说明热带地区可能对全球气候存在重要的影响。

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。

Ore deposit, have been studied detailly; the orebody pattern (sedimental bedded ores combined with stringer ores of hydrothermal origin) is also outlined; four metallogenic epoches are devided; the zoning of mineralization (including zones of ores, elements, mineral assemblages and temperature of mineralization) have been depicted; the main types of wall-rock alteration are characterized as propylitization of basic rocks and pyritization-sericitization-silicification of acidic pyroclastic rocks; the origin of ores and seven kinds of main minerals have been studied; and the metamorphism and deformation of orebodies is thought mainly due to the shearing and the intrusion of subvolcanic rocks
