The formation and evolution of the Antarctic continent

Recent Major Achievements

1. The researchers comprehensively discussed regional metallogenic background of the Altyn Tagh area,
    delimitated the regional metallogenic belt, proposed the possibility of the existence of multi-metal deposits,
    mostly copper and gold, based on in-depth summary of the newly discovered copper-gold deposit or ore-
    forming geological conditions, mechanisms and models, and made the breakthrough in the regional ore
    deposit discovery.


2. With the systematic investigations and researches on active tectonics along the Qinghai-Tibet and Yunnan-
    Tibet railways and their adjacent areas, researchers comprehensively summarized the geometric and kine-
    matics characteristics of active faults in the south-central Qinghai-Tibet Plateau, revealed the basic features
    and rules of paleo-earthquake activities caused by normal faulting in the internal plateau, and explored the
    dynamics relations between the strong seismic activities of the internal Qinghai-Tibet Plateau and those
    in the central-eastern Chinese mainland.


3. Using the natural seismic surface wave tomography, researchers revealed the possible relations between
    the destruction of the lithosphere in Huabei Basin and the deep melt upwelling and lateral erosion, which
    may cause the lithosphere thinning in Tangshan-Xingtai seismic zone and be responsible for the Xingtai
    and Tangshan earthquakes.


4. In the northern margin of Huabei Block, researchers identified numerous Late Carboniferous-Early Permian
    intrusions. The northern margin of the North China Block was therefore determined as the active continental
    margin of the Andean-type. During the Late Permian-Early Triassic period, this continental margin underwent
     the post-collision/post-orogenic extension and intense exhumation, with the uplift of more than 15 km.


5. Researchers conducted deep reflection seismic detection and geological cross-section measurement in the
    Dabie orogenic belt, revealed the fine crustal structure of the Dabie orogenic belt and its structural similarity to
    the Alpine belt, proposed the diachronous subduction and exhumation model for the HP/UHP rocks, and sys-
    tematically illustrated the Jurassic intra-continental mountain reconstruction events in Dabieshan.


6. Researchers compiled the 1:500,000 geological map of the Prydz belt in Antarctica, established the geological
    structural frame of the Prydz belt, confirmed the Grove Mountain as the most typical Pan-African geological bodies
    in the Prydz belt, and found Pan-African high-pressure mafic granulites and revealed the collisional process of the
    Prydz belt.
