| 1 | Discovery of carbonaceous compressions and their multicellular tissues from the Changzhougou Formation (1 800 Ma) in the Yanshan range, North China显示文摘In 1997 and 1998, hundreds of specimens of megascopic carbonaceous compressions or algal fossils were found from - 1800-million-year old Changzhougou Formation, which is the lowermost unit of the latest Palaeoproterozoic Changcheng Group (~1 600-1 800 Ma) in the Xinglong-Kuancheng areas at the middle Yanshan Range, North China. They are discoid, ellipsoid and sausage-like, namely shaped like Chuaria Shouhsiennia (Ellipsophyta) and Tawuia. By adopting HF acid-resistant maceration coupled with scanning electron microscope and petrologic section, the authors made a preliminary research on the histology for some circular and ellipsoid carbonaceous compressions, namely Chuaria- and Shouhsienia-llke forms, in addition to their morphology. The following three types of multicellular tissues have been found in the fragments of them: colony-like, pseudoparenchyma-like and parenchyma-like. All of the new data about multicelluar tissues not only supply a very important basis in histology to determine the | ZHU Shixing SUN Shufen HUANG Xueguang HE Yuzhen ZHU Gengxin SUN Lixin ZHANG Kuan | 2000 | Chinese Science Bulletin2000，45，9： | 10 |
| 2 | Discovery of the Jiawengmen Stromatolite Assemblage in the Southern Belt of Eastern Kunlun, NW China and Its Significance显示文摘This paper reports a newly discovered Late Mesoproterozoic–Early Neoproterozoic stromatolite assemblage, named here the “Jiawengmen stromatolite assemblage”, represented by a Conophyton-Baicalia association in the Jiawenmen area in the southern belt of the Eastern Kunlun. This stromatolite assemblage is dominated by large-scale conical stromatolites and related elements, i.e., Conophyton garganicus var. inkeni, C. cf. ressoti Menchikov, Jacutophyton cf., Conicodomenia f., which commonly co-exist with elements of the group of Baicalia. This assemblage can be correlated with that of the middle Jixian-middle Qingbaikou System in North and Northwest China, but is different from that in South China. Correlation can also be made with that in the upper horizon of the Middle Riphean-lower horizon of the Upper Riphean in the South Ural Mountains and Siberia of Russia, in North Africa, and in the Alaskan Peninsula of North America. These facts suggest that the Jiawengmen stromatolite assemblage probably colonized during 1300–850 Ma ago. Accordingly, the stromatolite-bearing carbonate rocks are then proposed to correspond to the middle Jixian System-middle Qingbaikou System or the upper Middle Riphean-lower Upper Riphean. Our stromatolite data further suggest that a Precambrian microblock, named the Xialawen microblock here, occurred in the southern belt of Eastern Kunlun, the western part of the Maqên microblock. Similar stromatolite assemblages in the Maqên microblock and those blocks that occurred in North China, Siberia and North Africa point to similar paleogeographic and paleoenvironmental conditions. These microblock and blocks were probably located at low latitudes and on the continental margins of the Rodinian supercontinent, where warm epicontinental seas were favorable to widespread colonization of stromatolites during the Late Mesoproterozoic-Early Neoproterozoic. However, these stromatolite assemblages are quite different from those of the South China block, which is suggestive of different paleogeographic contexts, and probably also of a different tectonic affinity. | BIAN Qiantao ZHU Shixing I.

| 3 | Biotic evolution and its relation with geological events in the Proterozoic Yanshan Basin, North China显示文摘The Yanshan Basin,located in northern North China,underwent three primary stages in the Mesoproterozoic,and corresponding biotas have been summarized for each stage in the present study.The three stages are stage A(the lower part of the Changcheng Group which dominated by clastic sediments),stage B(the upper part of the Changcheng Group to the Jixian Group which characterized by carbonate sediments),and stage C(the upper part of the Jixian Group which dominated by clastic sediments).This paper will focus on the evolution of biota during stage B.Microbiota of the stage B exhibits a high level of diversity and abundance.Planktonic microfossils have various forms and complex decorations.Most microfossils are small.In stage B,there was great variation in the biotic abundance and diversity,the average diameter of spherical benthic microfossils,and the maximum diameter of the spherical microfossils.We analyzed these parameters and identified two typical biotic events,and both biotic events were corresponded with geological events.The first event occurred in the third member of the Dahongyu Formation.In this era,the maximum diameter of the silicified microfossils significantly increased,and large,spherical planktonic specimens are abundant.The flourishing of large organisms in the strata is presumably related to volcanic activity.The second event occurred in the third member of the Gaoyuzhuang Formation.During this era,the microfossil assemblage changed significantly.The changes correspond with a decline in stromatolites as well as the transformations of the carbon isotope ratios and the elemental geochemistry. | SHI Min FENG QingLai ZHU ShiXing | 2014 | Science China Earth Sciences2014，57，5： | 4 |

| 7 | In-situ energy calibration of SSRF macromolecular crystallography beamline using powder diffraction显示文摘For X-ray powder diffraction spectra collected by an area detector of MarCCD on macromolecular crystallography beamline of SSRF,an energy calibration method was developed using LaB_6(660a) powder diffraction for in-situ rapid energy calibration of the X-rays without changing the experimental conditions.The intensity of each diffraction ring was integrated,and the accurate peak positions were fitted by Pseudo-Voigt function model.The sample's interplanar spacing for XRD analysis and the calibrated energy were obtained by the PCPDFWIN code and by fitting all the energies with the least-square method.The exposure time and the sample-to-detector distance were found no effect on accuracy of the energy calibration,and the in-situ energy calibration could be done with an accuracy of better than 0.4‰in 7-18 keV.This method is applicable to other X-ray beamlines. | Tao Shixing Zhu Jing Niu Jing Chen Mingzhi Liu Ke Wang Yu Wang Qisheng Sun Bo Huang Sheng Tang Lin He Jianhua | 2010 | Nuclear Science and Techniques2010，21，6： | 1 |

| 12 | One-step preparation of carbon nanotubes with nickel as the core显示文摘CNTs with core-shell structure were successfully synthesized by a microwave-assisted polyol method,and magnetic Ni nanoparticles were employed as a catalyst. The preparation method is fast and simple. The structures,morphology and magnetic properties of the as-synthesized samples were investigated using Raman spectrometer,X-ray diffraction (XRD),transmission electron microscopy (TEM),vibrating sample magnetometer (VSM),respectively. The XRD results suggested that Ni particles used as a catalyst in our experiment were nano-sized. In this paper,magnetic Ni nanoparticles were employed as a catalyst,and an electric spark on metal Ni nanoparticles with the microwave eddy current effect could induce CNTs’ formation with the further reaction. The length of hollow carbon nanotubes was micro-sized and the diameters of most of the CNTs were varying from 18 to 20 nm according to the TEM images. Magnetic measurements demonstrated that CNTs with core-shell structure indicated a characteristic ferromagnetic behavior compared with Ni nanoparticles. | RUAN Zheng LIU XianSong HU Feng ZHU DeRu CHENG ChunHao QIU ShiXing ZHOU Dan GAO HuaMin JIA DaoNing WANG PengPeng | 2011 | Science China(Technological Sciences)2011，54，1： | 1 |
