Strong evidence for couplings between the ionospheric wave-4 structure and atmospheric tides[09 13, 2011]

Ph. D. student HE Maosheng and his teacher LIU Libo explore evidence for the electrodynamic coupling and the ionospheric signatures of direct penetration of tides to evaluate the contributions from the main processes.
  They investigate the wave...

Luminescence sensitivities of quartz grains from eolian deposits in northern China and their implications for pro...[09 05, 2011]

Ph.D. student Lü Tongyan and her teacher SUN Jimin use the luminescence sensitivities of quartz grains to study the provenance of deserts. In this study, nine modern dune sand samples were collected from different deserts. Moreover, they also col...

Equinoctial asymmetry of ionospheric vertical plasma drifts and its effect on F-region plasma density[09 01, 2011]

Postdoctor REN Zhipeng and his teacher WAN Weixing research the equinoctial asymmetry of ionospheric vertical plasma drifts based on observations from ROCSAT‐1 during 1999 to 2004.
  It is found that the observed asymmetry exhibits obvious loca...

Mesoproterozoic carbonatitic magmatism in the Bayan Obo deposit, Inner Mongolia, North China[08 31, 2011]

Postdoctor YANG Kuifeng and his teacher FAN Hongrui study detailed data from the different types of carbonatite dykes occurring in a larger area around the Bayan Obo rare-earth element ( REE) deposit, as well as from the massive ore-hosting dolomi...

Reducing two-way splitting error of FFD method in dual domains[08 23, 2011]

Vice professor ZHANG Jinhai and his teacher YAO Zhenxing develop a method to reduce two-way splitting error of FFD method. They compensate the two-way splitting error in dual domains, alternately in the spatial and wavenumber domains via Fourier t...

Processes affecting isotopes in precipitation of an arid region[08 22, 2011]

Professor PANG Zhonghe and his team research the isotopic composition of precipitation in northwest China.
  They have analysed samples taken from individual precipitation events at two neighboring high-altitude stations in the Tianshan Mountain...

Geochemistry and Sr–Nd–Pb–Hf isotopes of the Mesozoic Dadian alkaline intrusive complex in the Sulu orogenic belt[08 12, 2011]

Ph.D. student LAN Tingguang and his teacher FAN Hongrui report the geochronological, petrological and geochemical data on the Dadian complex, with an aim to constrain its petrogenesis and tectonic setting within the Sulu orogenic belt. The Dadian ...

Mesoproterozoic mafic and carbonatitic dykes from the northern margin of the North China Craton[07 27, 2011]

Postdoctor YANG Kuifeng and his teacher FAN Hongrui report the occurrence and characteristics of abundant carbonatite and mafic dykes from around the Bayan Obo giant rare earth element (REE) deposit in the northern margin of the North China Craton...
