Zircon U-Pb dating for three large granitoid batholiths,geochemical and Hf isotope analyses for two of them have been carried out in the different blocks of the Qinling.Zircon dating by LA-ICPMS for the Lantian granitoid in the southern margin of the North China Block gives an age of 133±1Ma.The granitoids show whole-rock eNd(t)=-11.8~-18.3,zircon eHf(t)=-37.7~-5.7.The Muhuguan and the Mangling granitoids in the North Qinling orogen yield zircon LA-ICPMS and SHRIMP age of 150±1Ma and 149±2Ma… 
Provenance of Late Mesozoic Strata and Tectonic Implications for the Southwestern Ordos Basin, North China: Evidence from Detrital Zircon U−Pb Geochronology and Hf Isotopes
In order to determine the provenance and variation characteristics of sandstone-type uranium deposits located in the southwest Ordos Basin, U−Pb geochronology and Hf isotope analyses were conducted
Reworking of the Juvenile Crust in the Late Mesozoic in North Qinling, Central China
The Qinling Orogen resulted from the collision between the North and South China blocks in the Triassic. Mesozoic granitoids, ranging from the Triassic to the Cretaceous, are widely distributed in
Petrogenesis, zircon U–Pb age, and geochemistry of the A-type Mogou syenite, western Henan Province: Implications for Mesozoic tectono-magmatic evolution of the Qinling Orogen
The Mogou syenite intruded into the Mesoproterozoic Xiong’er Group is the main lithostratigraphic unit, along the southern margin of the North China Craton (NCC). This paper reports zircon LA-ICP-MS
Geochronology, Geochemistry and Hf Isotope of the Late Meso- zoic Granitoids from the Lushi Polymetal Mineralization Area: Implication for the Destruction of Southern North China Craton
The North China Craton (NCC) is the best example of an Archean craton that has lost its stability in the Late Mesozoic. Although the cratonic destruction is generally considered to have occurred in
