Is the Jurassic (Yanshanian) intraplate tectonics of North China due to westward indentation of the North China block? [PDF]
Terra Nova, 2012 International audienceThe northern mountains of Beijing are the type locality of the Mesozoic Yanshanian orogen. Our structural study emphasizes the importance of dextral strike-slip for the formation of this intracontinental belt.

Tectonic evolution and mineralization exploration of Lujing uranium ore field, South China [PDF]
Scientific ReportsGranite-type uranium deposit is one of the most important uranium deposit types in China, with orebodies strongly controlled by structures. Previous studies of the Lujing ore field mainly focused on metallogenic genesis and Yanshanian structure, which ...

Late Jurassic Leucogranites of Macau (SE China): A Record of Crustal Recycling During the Early Yanshanian Orogeny [PDF]
Frontiers in Earth Science, 2020 The Yanshanian Orogeny consists of Jurassic to Cretaceous compressional-extensional cycles related to the subduction of the Paleo-Pacific Ocean beneath East Asia. Numerous granitic plutons were emplaced across southeast China at distinct intervals over a

Oxygen fugacity of Yanshanian granites in South China and implications for metallogeny
Ore Geology Reviews, 2017 Abstract Oxygen fugacity ( fo 2 ) of magmas exerts an important control on the speciation of multivalent elements in magmatic-hydrothermal processes, which has a great significance for mineralization. This paper examines the relationships between oxygen fugacity and mineralization associated with Yanshanian (Jurassic to Cretaceous) granites in South

“Yanshanian Movement” induced by the westward subduction of the paleo–Pacific plate
Solid Earth Sciences, 2020 Mountain building (orogeny) has a strong causal relationship with compression induced by plate drifting. It is generally accepted that orogenic belts are distributed perpendicular to the direction of plate movement.

Yanshanian (Late Mesozoic) ore deposits in China – An introduction to the Special Issue
Ore Geology Reviews, 2017 Abstract The Late Jurassic-Cretaceous Yanshanian Orogeny (or “Yenshan Movement”), one of the most important tectonothermal events, is first recognized in China, especially eastern China. This Late Mesozoic orogeny, which was initiated most likely by a Mesozoic tectonic switch, strongly reworked or destructed the older continental lithospheres or ...

On the genetic classification and tectonic implications of the Early Yanshanian granitoids in the Nanling Range, South China [PDF]
Science Bulletin, 2007 Early Yanshanian (Jurassic) granitoids are widespread in the Nanling Range of South China, and are associated with numerous non-ferrous and rare metal mineral deposits. These granitoids consist mainly of slightly peraluminous biotite monzogranites and K-feldspar granites that are closely associated in time and space with subordinate amphibole-bearing ...
