The enclaves from rapakivi-textured granite plutons in the Qinling orogenic belt are mainly dioritic magmatic enclaves, having low content in SiO2(50%-62%),high in K2O+Na2O(7.01%-9.4%), δ(5-9), F, REE, Cr, Ni, V and Ga. The major oxide contents of the enclaves and their host rocks plots on the same linear trends. The pattern of REE, trace element and isotopic signatures of the enclaves are similar to those of the host granites. Exchanges of active elements, HLE and LREE occurred between the… 
Age, origin, and tectonic implications of Palaeozoic rapakivi granites in the North Qaidam orogen, Northwest China
Palaeozoic rapakivi granites occur in the western segment of the China Central Orogenic System. Exhibiting typical rapakivi texture, these granites contain magmatic microgranular enclaves of
The characteristics, origin, and significance of mafic microgranular enclaves in the granitoids from the Bailingshan complex, Eastern Tianshan, NW China
The Bailingshan complex is located to the south of the Jueluotage tectonic belt of Eastern Tianshan, consisting of quartz monzodiorite, granodiorite, monzogranite, and granite. Mafic microgranular
Structure, geochronology, and petrogenesis of the Late Triassic Puziba granitoid dikes in the Mianlue suture zone, Qinling orogen, China
We present structural field observations, in situ zircon U-Pb ages, Hf isotopic compositions, geochemistry, and Sr-Nd isotope data from the Puziba granitoid intrusions in the Qinling orogenic belt
Ages of the Laocheng Granitoids and Crustal Growth in the South Qinling Tectonic Domain, Central China: Zircon U‐Pb and Lu‐Hf Isotopic Constraints
The Laocheng granitoid pluton is located in the South Qinling tectonic domain of the Qinling erogenic belt, southern Shaanxi Province, and consists chiefly of quartz diorite, granodiorite and
Slab Breakoff Model for the Triassic Post-Collisional Adakitic Granitoids in the Qinling Orogen, Central China: Zircon U-Pb Ages, Geochemistry, and Sr-Nd-Pb Isotopic Constraints
Triassic granites in the Qinling orogen of central China provide insights into regional tectonomagmatic events and tectonic evolution. Zircon LA-ICP-MS U-Pb dating shows that the Yangba, Xichahe,
