Reactivation of the Archean Lower Crust: Implications for zircon geochronology, elemental and Sr–Nd–Hf isotopic...[09 13, 2012]

Vice Professor YANG Kuifeng and his team investigate the Late Jurassic Linglong and Luanjiahe granites and report zircon U-Pb emplacement ages of 157-159 Ma. Based on detailed petrological, geochronological and geochemical studies on the Late Meso...

Slab-derived lithium isotopic signatures in mantle xenoliths from northeastern North China Craton[09 03, 2012]

In-situ lithium (Li) concentrations and δ7Li of olivine, orthopyroxene (opx) and clinopyroxene (cpx) in mantle xenoliths from the Quaternary Longgang maar provide insights into the nature and evolution of the lithospheric mantle beneath the easte...

Simultaneous Determination of 143Nd/144Nd and 147Sm/144Nd Ratios and ...[08 31, 2012]

Senior engineer LI Chaofeng and his team develop a new method of acquiring both ratios of 143Nd/144Nd and 147Sm/144Nd and concentrations of Sm-Nd simultaneously on the same filament arrangement by modified isotope dilution thermal ionization mass ...

Glacial-interglacial water cycle, global monsoon and atmospheric methane changes[08 30, 2012]

Professor GUO Zhengtang and his team explore the CH4 signals in the Antarctic EPICA Dome C and Vostok ice records using the methods of time series analyses and correlate them with insolation and geological records to address the causes of atmosphe...

Two-phase growth of high topography in eastern Tibet during the Cenozoic[08 29, 2012]

Professor WANG Erqi and his team use thermochronology to measure the cooling histories of rocks exposed in a section that stretches vertically over 3km adjacent to the Sichuan Basin. Their thermal models of exhumation-driven cooling show that thes...

The role of crustal contamination in the formation of Ni-Cu sulfide deposits in Eastern Tianshan[08 28, 2012]

Postdoctor TANG Dongmei and Professor QIN Kezhang research the role of crustal contamination and the addition of crustal sulfur and its degree on the Tulaergen, Huangshandong, Xiangshan, Baishiquan and Tianyu Permian magmatic sulfide deposits in E...

Spatial distribution of seismic layer, crustal thickness, and Vp/Vs ratio in the Permian Emeishan Mantle Plume re...[08 16, 2012]

Postdoctor WU Jing and Professor ZHANG Zhongjie present the lithosphere rheology structure derived from seismic activity and the spatial distribution of seismic energy release, which records the lithospheric deformation from the Late Permian mantl...

Compensation for transmission losses based on one-way propagators in the mixed domain[08 08, 2012]

Postdoctor SUN Weijia and his teacher FU Liyun present a method to compensate for transmission losses using one-way wave propagator for a 2D case.
  The compensation of transmission losses (CTL) scheme is composed of transmission term and a phas...
