The Yanshanian Orogeny and Two Kinds of Yanshanides in Eastern-Central China

Acta Geologica Sinica - English Edition, 2005
The Tan-Lu Fault was once a transform fault in the Paleotethys, west of which was the Qinling-Dabie Ocean separating the Yangtze Craton from the North China Craton, and east of which was the Su-Lu Ocean separating the Su-Wan Block from the Jiao-Liao Craton. The Qinling-Dabie Ocean closed in the Indosinian orogeny, which created the China-Southeast Asia

Jurassic–Cretaceous tectonic evolution of Southeast China: geochronological and geochemical constraints of Yanshanian granitoids

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 ...

Yanshanian Orogeny During North China's Drifting Away From the Trench: Implications of Numerical Models

Tectonics, 2020
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 ...

Late Mesozoic tectonostratigraphic division and correlation of the Bohai Bay basin: Implications for the Yanshanian Orogeny

Science China Earth Sciences, 2019
We present the results of Mesozoic sequences of the Bohai Bay basin in North China, based mainly on geochronology and interpretations of seismic profiles and logging data. Five tectono-stratigraphic sequences are defined: Lower-Middle Triassic, Lower-Middle Jurassic, Upper Jurassic, Lower Cretaceous and Upper Cretaceous.

Three large-scale metallogenic events related to the Yanshanian Period in Southern China

2005
Post-orogenic magmatism during the Yanshanian Period in southern China caused three major metallogenic events in South China. The first took place from ∼180 to 170 Ma (Early Yanshanian), and produced Cu Pb-Zn and polymetallic mineralization in northeastern Jiangxi and southeastern Hunan.

Detachments and Magmatic Source Depth in Lithosphere of Eastern China During Yanshanian and Sichuanian Stages

Earth Science Frontiers, 2008
Abstract It is an important project for present tectonics, to precisely research the time and space of detachment formation in the lithosphere, in geological history. According to collect a lot of collected data of on the magmatic source depths for of Eastern China during Yanshanian (205–135 Ma) and Sichuanian (135–52 Ma) tectonic stages, it is a ...

The system of extensional structures developed in the late Yanshanian orogeny in the west of Shandong Province, China

Tectonophysics, 1994
Abstract The system of extensional structures in the west of Shandong Province is located on the east margin of the China continental block and on the west side of the Tangcheng-Lujiang fault. Complex crustal movements occurred in the region after the Late Triassic. The system of extensional structures is composed of a linked system of faults, formed

Petrology and geochronology of Xuejiashiliang igneous complex and their genetic link to the lithospheric thinning during the Yanshanian orogenesis in eastern China

Lithos, 2007
The Xuejiashiliang igneous complex, ∼150 km north of the City of Beijing, is an important member of the Mesozoic Yanshanian orogen in eastern China. This complex consists of gabbro, monzogabbro, monzonite, syenite and granite. In situ zircon U/Pb dating shows that the Xuejiashiliang complex was emplaced at ∼128.8–123.7 Ma (i.e., K1 1 ).

Petrogenesis and significance of early Yanshanian syenite-granite complex in eastern Nanling Range

Science in China Series D, 2005
In the eastern Nanling Range there exists the early Yanshanian syenite-granite assemblage. A representative example is the Pitou-Tabei complex composed of the Tabei syenite pluton and the Pitou syenogranite pluton in southern Jiangxi Province. U-Pb zircon dating yields ages of 188.6±2.2 Ma for the Tabei pluton and 186.3±1.1 Ma for the Pitou pluton. The

Geochronology of Yanshanian Magmatism and Metamorphism in the Hinterland of the Dabie Mountains and Their Geologic Implications¹

Acta Geologica Sinica - English Edition, 1992
Abstract A strong tectono‐magmatic thermal event has been revealed by field observations of granitic, migmatitic and metamorphic rocks in the hinterland of the Dabie Mountains. K‐Ar, Ar‐Ar and Rb‐Sr determinations show that the event took place 133–117 Ma ago (Yanshanian).
