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

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).

Early Yanshanian post-orogenic granitoids in the Nanling region?? Petrological constraints and geodynamic settings

Science in China Series D, 2002
Early Yanshanian magmatic suites predominate absolutely in the Nanling granite belt. They consist mainly of monzogranite and K-feldspar granite. There occur associations of early Yanshanian A-type granitoids (176 Ma—178 Ma) and bimodal volcanic rocks (158 Ma—179 Ma) in southern Jiangxi and southwestern Fujian in the eastern sector of the granite belt ...

Genesis and Tectonic Setting of Yanshanian Magmatic Rocks in the Northern Margin of South China Sea

  Yanshanian magmatic rocks are widely distributed in the northern margin of the South China Sea and the continental margin of South China. These magmatic rocks are generally believed to have been formed by the subduction of the Paleo-Pacific plate to the South China Plate from Late Jurassic to Early Cretaceous.

Tectonics of Jurassic-Early Epoch of Early Cretaceous (The Yanshanian Tectonic Period, 200–135 Ma)

2010
The Yanshanian movements were first recognized by Weng WH (1927, 1929) in Yanshan area, 116°–119.5°N, 40°–42°E. Since then the Yanshanian has been used as a local term in China for tectonic events which occurred mainly during the Jurassic Period. Later, (1929), (Huang JQ 1945, 1960) and Zhao ZF (1959) extended the term to cover tectonic events which ...
