Cogenetic origin of mafic microgranular enclaves in calc-alkaline granitoids: The Permian plutons in the northern North China Block

, 2017
Mafic microgranular (microgranitoid) enclaves (MMEs) with fine-to medium-grain–size igneous microstructures are abundant in Permian granitoid plutons in the northern North China Block (NCB).

Subduction between the Jiamusi and Songliao blocks: Geochronological and geochemical constraints from granitoids within the Zhangguangcailing orogen, northeastern China

, 2017
Bulk-rock major and trace element, Sr-Nd isotopic, and zircon U-Pb-Hf isotopic data are reported for Jurassic igneous rocks from a north-south traverse through the Zhangguangcailing orogen, which formed by the subduction of an ocean and final collision ...

STRUCTURAL EVOLUTION OF THE CHEKA PLUTON (SOUTHERN URALS): PETROMAGNETIC STUDIES AND FRACTURE ANALYSIS

Геодинамика и тектонофизика
The Cheka pluton, located in the Magnitogorsk megazone of the Southern Urals and composed of the alkaline granitoids, is meridionally elongated (1–2)×6.5 km. The fracture and anisotropy of magnetic susceptibility analysis was made on the Cheka pluton for
