Abstract Yanshanian (ca. 200–100 Ma) metallogeny of eastern Asia was dominantly controlled by oblique subduction and rollback of the Izanagi plate, and also, more locally in the north, by closure of the Mudanjiang Ocean basin and accretion of the Bureya-Jiamusi-Khanka block and the Sikhote-Alin terranes.

Revisiting of the Yanshanian basins in western and northern Beijing, North China
Journal of Asian Earth Sciences, 2018Abstract We present new laser ablation–inductively coupled plasma–mass spectrometry (LA–ICP–MS) zircon U–Pb ages and provenance data for the Yanshanian basins in western and northern Beijing, North China, with the aims of demonstrating the relationship between basin evolution and “Yanshanian tectonism” and constraining the Late Jurassic–Early ...

The relationship between the Yanshanian Movement, destruction of the North China Craton (NCC), and subduction of the western Pacific plate is crucial to reconstructing the middle-late Mesozoic tectonic evolution of the eastern Asian continent and margin. The Yanshanian Movement was a globally important change in crustal tectonics during the Middle-Late

International Geology Review, 2013
We report results of laser ablation inductively coupled plasma-mass spectrometry-based dating, as well as the analysis of bulk-rock major and trace elements, and Sr–Nd isotopes to address the genesis and tectonic settings of the Yanshanian granitoids in neighbouring sections of Zhejiang, Jiangxi, and Anhui provinces (the WZG region) within the Yangtze ...

Sulfur Isotopic Variation of Yanshanian Magmatic‐hydrothermal Deposits in Southern China
Resource Geology, 2000Abstract: Sulfur isotope data (δ34S) of sulfides of more than 6700 samples from 157 ore deposits associated with Early and Late Yanshanian granitic and volcanic activities in South China are reviewed and summarized. Averaged δ34S values of individual deposits vary from ‐9. 3 to +20.

What is the main mechanism for the Yanshanian magmatism?
AIP Conference Proceedings, 2012We take the quantitative assessment of underplating and delamination mechanism of Yanshanian magmatism. The compare results show the delamination mechanism can supply about 340 times more heat flux than the underplating mechanism and match the surface two magmatism distribution regions.

AbstractTectonics in North China and adjacent areas were dominated by the Pacific Plate subduction since the Jurassic. Although the extension‐dominated tectonics in North China since the Early Cretaceous can be well explained by the Pacific Plate subduction, it is still not well understood why North China and adjacent areas underwent intense ...

Petrogenesis and metallogenesis of the Yanshanian adakite-like rocks in the Eastern Yangtze Block
Science in China Series D Earth Sciences, 2003Many of the Yanshannian intermediate-acid intrusive rocks related to Cu-Au mineralization in the Eastern Yangtze Block are characterized by high Al 2 O 3 , Sr contents, while low in Y, Yb contents, thus with high Sr/Y, and La/Yb ratios, and variational isotope signatures in particular, e.g.

The pre-Yanshanian (pre-200 m.y.B.P.) geology of Asia can be interpreted as an unique record of numerous small plates, some of which were separate rifted blocks as early as 1,500 m.y.B.P. The north-south agglomeration of these blocks to form the bulk of modern Asia began in the west during the Carboniferous (Hercynian events) and climaxed in the east ...
