Prof. JIANG Hongchen, Dr.YANG Jian and Dr. HAN Mingxian from the State Key Laboratory of Biogeology and Environmental Geology found that positive priming effects induced by allochthonous and autochthonous organic matter input occur in the lake sediments with different salinity. The results are published in Geophysical Research Letters. The abstract of the article is as follows.Global warming ch...

Mammals including humans only replace teeth once in a lifetime. After baby teeth are shed, permanent teeth will accompany us for the rest of our life. In reptiles, however, teeth are constantly replaced in a wave-like pattern during their lifetime. So how did dinosaurs replace their teeth?Triceratops from the Late Cretaceous of North America is famous for bearing horns and frills, but it is lik...

Ichthyosaurs are a group of successful Mesozoic marine reptiles that have a worldwide distribution, but their evolutionary origin is still unclear. In recent years, many new marine reptiles related to ichthyosaurs, and called early ichthyosauromorphs, have been found in rocks of Early Triassic age and shed light on the origin of ichthyosaurs. These early ichthyosauromorphs have been discovered ...

Recently, the research team led by Prof. CHEN Jiehong in China University ofGeosciences,Wuhan, published new study associated with pre-earthquake anomalous phenomena in the Journal of Earth and Space Sciences. The results suggest that humanity would get a key to resolving the scientific issues of pre-earth quake anomalous phenomena. The team established a novel monitoring system, which is honor...

Recently, the research group led by Professor Timothy Kusky, director of the Central for Global Tectonics of our university, published a paper "Archean eclogite-facies oceanic crust indicates modern-style plate tectonics" in the prestigious top-rated journal PNAS(Proceedings of the National Academy of Sciences of the United States of America). The authors identified residual oceanic crust of ec...

The research group led by Professor Tim Kusky, director of the Center for Global Tectonics, published a paper, "Alpine-style nappes thrust over ancient North China continental margin demonstrate large Archean horizontal plate motions ", on Nature communication.The first author is Zhong Yating, a doctoral student of the school of Geosciences of our university, and the co-corresponding authors ar...

Intensive volcanism has been considered a major driver of environmental/climatic changes through Earth history, including global warming due to volcanogenic CO2 emissions, ocean acidification, and atmospheric ozone depletion, which are regarded as potentially important killing mechanisms during mass extinctions of life. However, direct evidence of a linkage between volcanism and environmental/c...
