A single-step separation scheme is presented for Sm-Nd radiogenic isotope system on very small samples (1-3 mg) of silicate *** method is based on Eichrom LN Spec chromatographic material and affords a straightforward separation of Sm-Nd from complex matrix with good purity and satisfactory blank levels,suitable for thermal ionization mass spectrometry(TIMS). This technique,characterized by high efficiency(single-step Sm-Nd separation) and high sensitivity (TIMS on NdO ion beam),is able to process rapidly(3-4h),with low procedure blanks(10pg) and very small sample(1-3 mg).Replicate measurements by TIMS on Nd/Nd ratios and Sm-Nd concentrations are presented for eleven international silicate rock reference materials,spanning a wide range of Sm-Nd contents and bulk *** analytical results show a good agreement with recommended values within±0.004%for the Nd/Nd isotopic ratio and±2.for Sm-Nd quantification at the 95%confidence *** is noted that the uncertainty of this method is about 3 times larger than typical precision achievable with two-stage full separation followed by state-of-the-art conventional TIMS using Nd ion beams which require much larger amounts of ***,our single-step separation followed by NdO ion beam technique is preferred to the analysis for microsamples.

Thick,Proterozoic,unmetamorphosed carbonate-dominated successions are widely distributed in the North china *** Ming Tombs Section near beijing is a well-studied stratigraphic section and has been selected for the study of secular variations in the carbon isotopic composition of marine *** ascen{2. order,this section includes the Changzhougou,Chuanlinggou,Tuanshanzi, Dahongyu and Gaoyuzhuang formations in the Changcheng Group;the Yangzhuang,Wumishan,Hongshuizhung,and Tieling formations in the Jixian Group;and the jing’eryu Formation in the Qingbaikou *** the depositional ages of the Changzhougou,Chuanlinggou and Tuanshanzi formations of the Changcheng Group are older than 1600 Ma,the Gaoyuzhuang,Yangzhuang and Wumishan formations belong to the Mesoproterozoic Era with ages evidently greater than～1300-12.0 Ma,and the jing’eryu Formation of the Qingbaikou Group were deposits of the early Neoproterozoic Era.δC values vary only within a narrow range between - 1.6 and + 1.5 permil in the early Mesoproterzoic Gaoyuzhuang,Yangzhuang and Wumishan *** variation inδC of carbonates from the early Neoproterozoic jing’eryu Formation is more significant,showing values from -0.5 to +3.3 *** secular variations inδC values of carbonates from the Proterozoic successions in the Ming Tombs Section can be broadly correlated with those in the Jixian Section of the North china *** compare well with the established global isotopic curve of the Mesoproterozoic and Neoproterozoic eras.

作者首次提出苏皖地块是特提斯演化阶段一个独立的构造单元。基于火成岩及变质岩和古地磁的研究成果认为苏鲁洋在晚侏罗—早白垩世最终闭合 ,苏皖地块与华北克拉通碰撞而出现高原 ,因而中国东部燕山期高原性质上应属碰撞高原。文中还讨论了高原边缘的冲断 -推覆带和其内部的复杂结构 (包括沿主碰撞 -剪切带发育的相对高峻地带和相对开阔的山间磨拉石盆地 ) ,认为该高原是规模宏伟的东亚燕山造山系中变形变质相对弱的部分。高原自早白垩世末起坍塌 ,晚白垩世是东亚燕山造山系的全面坍塌期 ,第三纪时燕山期高原已不复存在。强烈的岩浆活动不仅使苏皖地区 ,也使胶东、小秦岭、赣东北等地的燕山期成矿具明显的区域专属性。晚中生代—新生代的构造事件造成苏皖—黄海地区岩石圈强度低、地热梯度高。

[1]The longest total solar eclipse of this century occurred in East and South Asia on 2.

Enhancements of TEC due to the storm are observed after the main phase *** relative drop of TEC due to the solar eclipse is evidently larger at lower latitudes than that at higher ones and around noontime than that in the *** modeling work,we find that the latitudinal dependence of the TEC response may result from latitudinal variation of magnetic inclination,which influences the diffusion of ionization among different ***,the local time dependence of TEC response is closely related to the local time variation of background atmosphere density,which affects the electron loss efficiency in the ionosphere.
